Spring peepers (Pseudacris crucifer) are small, slender tree frogs found throughout much of the eastern part of North America. Like most frogs, spring peepers reproduce by laying eggs.

These eggs are laid in shallow, fish-free freshwater bodies and attached to submerged vegetation near the water’s surface.

Unlike most frogs which lay their eggs in masses, Spring peepers lay their eggs in small clusters, usually in rows attached to the same stick.

Learning about Spring peeper eggs is great to add to your knowledge and feed your curiosity. Read on to find out everything you need to know about Spring peeper eggs including some really interesting facts, as well as how to easily identify them.

When Do Spring Peepers Lay Their Eggs?

Spring peepers breed in southern areas from breed October to March, depending on the environmental temperature. In Northern areas, they breed from March to June, when the first spring rains come.

Spring peepers are often one of the first frogs to start breeding in the spring, not long after the ice melts on the wetlands.

For many people in the eastern and upper midwestern United States, their peeping is often an indicator that spring has arrived.

Spring peepers will usually start their breeding calls when the ambient temperature is (82.4°F) 28°C.

Where Do Spring Peepers Lay Their Eggs?

Spring peepers prefer to breed in shallow, temporary, or semi-permanent wetlands and ponds – that are only present in the spring and dry up as the year progresses.

Spring peeper breeding habitats include woodland ponds, vernal pools, flooded fields, flooded ditches, open marshes, swamps, wet meadows, cypress heads, and pine barrens.

In general, ideal spring peeper breeding ponds are near woods and are large and permanent enough to support emergent vegetation, but too shallow and temporary to contain fish.

Like many other amphibians, Spring peepers will typically avoid breeding in water with fish, as fish often prey on amphibian eggs and larvae.

How Do Spring Peepers Lay Their Eggs?

Male spring peepers arrive first at the breeding sites and will gather at the edges of pools by the hundreds – hidden near the bases of shrubs or grasses.

Each male establishes a small territory (usually occupying the immediate area around an individual) and begins calling for females.

This call is described as a high-pitched “peep peep peep”, repeated about 15-20 times per minute. The louder and faster he peeps, the better his chances of attracting a receptive female.

Listen to Spring peepers calling:

The males usually compete in trios, and the one who starts each round is usually the deepest-voiced.

Female spring peepers choose their mates based on the speed and volume of the male’s calls. Larger males are also typically preferred.

Once the female finds the male they are most attracted to they let the male know by nudging him.

The male then grasps the female behind her forelimbs in a tight mating embrace called ‘amplexus’.

Once in the amplexus embrace, the pair will swim around as the female chooses a site to lay her eggs. The female then lays her eggs in jelly-like strings, and the male releases sperm into the water, to fertilize the eggs as the female lays them.

Unlike many frogs which lay their eggs in masses, Spring peepers lay their eggs singly or in clumps of two or three.

The eggs are attached to submerged vegetation or debris, just below the surface of the water.

How Many Eggs Do Spring Peepers Lay?

A single female Spring peeper can lay 900 to 1,000 eggs each breeding season.

Each frog will only lay eggs once yearly, and will not breed multiple times in the same season.

Why Do Spring Peepers Lay So Many Eggs?

Spring peepers, like other frogs, lay large numbers of eggs as a natural way to counter the extremely high mortality rates they experience in their early life stages.

Spring peepers leave their eggs shortly after laying them. This means the eggs (and tadpoles) are vulnerable to predators, and environmental conditions – leading to very low survival rates.

Of the tadpoles that hatch, there will be intense competition for food and limited resources, meaning again the number of tadpoles will naturally thin out.

When the froglets leave the water, only a few will live to adulthood and reproduce – which can be as low as 1%. The rest will get eaten by predators such as birds, snakes, larger frogs, and small mammals such as foxes.

The large number of eggs laid by each frog is crucial to the survival of its species. If just 5 out of 1,000 eggs laid becomes an adult frog and lives long enough to breed, the population of that species should increase.

What Do Spring Peeper Eggs Look Like?

Spring peeper eggs are very small and are deposited singly on leaf litter and other underwater substrate.

Due to their small size, Spring peeper eggs can be hard to see from a distance, so you need to use caution when looking for them – to avoid trampling them.

How Long Do Spring Peeper Eggs Take To Hatch?

Spring peeper eggs take about 6 to 12 days to hatch, depending on the environmental conditions.

The eggs will typically develop and hatch faster in warmer temperatures and slower in colder temperatures.

Spring peeper eggs laid in cooler weather will usually take longer to hatch than those laid in warmer weather.

What Do Spring Peeper Tadpoles Look Like?

Young spring peeper tadpoles are tan/brown with darker mottling and the tail fin is clear.

As the tadpoles age, they gain golden or brassy flecking on the body and large dark blotches along the edges of the tail fins.

The tadpoles typically grow to 3 to 4 cm in total length before metamorphosis.

Spring peeper tadpoles will complete their metamorphosis and transform into frogs about two to three months after they hatch.

Do Spring Peepers Care For Their Tadpoles?

Spring peepers do not attend to their tadpoles or care for them in any way.

Male Spring peepers will not provide any parental care or investment after fertilization.

Female Spring peepers supply their eggs with nourishing yolk, but once they lay their eggs, they leave the pond, only returning the next breeding season.

What Animals Prey on Spring Peeper Eggs & Tadpoles?

Spring peeper eggs are preyed on by many animals including newts, turtles, leeches, dragonfly larvae, diving beetles, and other large water bugs.

Once the tadpoles hatch, they are preyed on by

  • Fish (if present in the pond)
  • Dragonfly naiads
  • Giant water bugs
  • Larger amphibian larvae, such as salamander larvae
  • Newts and salamanders
  • Some adult frogs, such as American Bullfrogs
  • Turtles
  • Water snakes
  • Wading birds, such as herons

What to Do if You Find Spring Peeper Eggs

If you live near a wooded area, especially near a pond, or another freshwater body there’s a chance of encountering Spring peeper eggs in the spring. If this happens, be sure to avoid disturbing the eggs.

Disturbing or removing the eggs from the water could damage them, or even kill the tiny embryos developing inside the eggs.

If you find frog eggs out of the water, it is best to leave them alone, especially if they are very near the water.

However, if you find frog eggs that were disturbed (by a human or animal) and taken out of the water, you could try to put them back in the water.

If the egg mass is still attached to a stick, very gently put the stick back in the water (just a few inches below the surface).

Still, the eggs are not guaranteed to hatch because the disturbance may have damaged them or killed the embryos developing inside.

Of course, there’s no harm in observing Spring peeper eggs from a distance.

Spring peepers (Pseudacris crucifer) are small, slender tree frogs found throughout much of the eastern part of North America. Like most frogs, spring peepers are obligate carnivores as adults, which means they eat animal protein instead of plants or vegetation.

Spring peepers are opportunistic predators – but they are mainly insectivores. In the wild, they eat worms, snails, slugs, mites, spiders, ants, beetles, flies, and a wide variety of other insects. In captivity, they can eat earthworms, crickets, small silkworms, and other soft-bodied insects. 

Spring peepers develop in two main life stages. They start their lives as tiny tadpoles that live entirely in the water. At this stage, they eat algae, plant tissue, and detritus in their aquatic environments.

After about 2 – 3 months, these tadpoles will through a process known as metamorphosis and develop into the adult form spring peepers that most people are more familiar with.

At this point, they become obligate carnivores, and will eat a wide variety of prey they can catch – but most of their diet will consist of ants and insects.

What Spring Peeper Tadpoles Eat in the Wild

Spring peepers start their lives as tiny embryos inside egg sacs. Their first food source for the developing embryos is the yolk of their eggs.

The yolk provides enough nutrition to sustain the developing tadpoles until they are ready to hatch into the water. This can take anywhere from 4 to 15 days.

After hatching, the tadpoles will have poorly developed gills, mouths, and tails – so they can not properly swim or eat yet.

For this reason, they will spend the first few days feeding on the remaining yolk of the eggs. This will provide them with enough energy to grow and develop further.

What spring peeper tadpoles eat in the wild

After about a few days, the tadpoles would have developed enough to start free swimming and feeding on food sources available in the water.

At this early stage, spring peeper tadpoles are almost completely herbivorous, and will eat:

  • Algae
  • Soft roots and leaves of aquatic plants (eg. duckweed mosses)
  • Phytoplankton
  • Detritus (mostly composed of degraded plant materials)

A few weeks into their development, the tadpoles start to grow legs, starting with the back legs. Their digestive tract will also gradually shorten.

Spring peeper tadpoles at this stage become omnivores and will eat animal matter in addition to plants.

They will also eat:

  • Aquatic insect larvae (glass worms, mosquito larvae, etc)
  • Water striders
  • Zooplankton
  • Small insects that fall into the water
  • Worms
  • Carcasses in the water

Whatever they eat, they will eat constantly. They have high energy demands because they are growing very rapidly. Growing big as fast as possible is necessary for survival, as they are an easy meal for most predators.

What Juvenile Spring Peepers Eat in the Wild

After 6 to 12 weeks, the tadpoles will go through a process known as metamorphosis, in which they will transform into juvenile frogs.

During metamorphosis, the thyroid gland secretes a growth hormone called thyroxine.

This hormone triggers the tadpoles to:

  • Lose the gills, and develop lungs for breathing air
  • Absorb the tail into the body
  • Grow strong legs for moving on land
  • Remodel other organs to form an adult frog

In addition, the digestive tract shortens dramatically, and the inner lining of the remaining intestine thickens, creating many folds in the process. These folds create a very large surface for the absorption of nutrients during digestion.

Once metamorphosis fully is complete, tiny spring peepers will leave the water and live on land.

At this point, spring peepers become obligate carnivores, which means they stop eating plant matter and will only eat animal-based foods.

 

What juvenile spring peepers eat in the wild

Their diet will shift away from aquatic prey and toward mainly terrestrial prey. However, since they are not fully grown yet, they can only eat small live prey.

Wild juvenile spring peepers will eat:

  • Ants
  • Mites
  • Small worms
  • Small snails, slugs
  • Spiders
  • Termites 
  • Springtails 
  • Crane flies
  • Fruit flies, and other small insects

As they grow in size, they will be able to eat slightly larger prey.

Once the transformation from tadpole to frog is complete, spring peepers will be instinctively attracted to movement while hunting for food. For this reason, they will only eat live prey and will avoid dead bugs.

What Adult Spring Peepers Eat in the Wild

Adult spring peepers are fully grown, meaning they have bigger mouths and stronger jaws. They basically eat a larger version of the diet they did as juveniles, but their larger size allows them to also eat things they did not eat as juveniles.

What adult spring peepers eat in the wild

Here’s a list of things that make up an adult spring peepers diet in the wild:

  • Termites, ants, flies, mosquitoes 
  • Pillbugs, ticks, mites springtails
  • Spiders, centipedes, millipedes, beetles 
  • Small slugs, snails, 
  • Small worms
  • Caterpillars, & other tiny insect larvae 
  • Moths, butterflies, flies, grasshoppers, tree crickets, and a wide variety of other insects 

Spring peepers are very opportunistic and will eat almost any prey small enough for them to swallow whole. It is believed that food is chosen more by availability and size than by actual preference.

These frogs are good climbers, but they generally do not climb high in tees, instead preferring to hunt in shrubs, thick grass, and other low vegetation.

Spring peepers living in deep, damp forests will hunt both during the day and night, whereas those found in woodland edges are mostly nocturnal and will restrict most hunting and other activity to night.

In addition, adult spring peepers most often come out to feed in the late afternoon and early evening, while juveniles are known to feed in the early morning to late afternoon.

What Adult Spring Peepers Eat In Captivity

Spring peepers are not common pets, so their exact captive diet requirements are poorly documented. However, given their diet in the wild, it is safe to assume that captive spring peepers would thrive on a diet close to that of other similarly sized tree frogs.

Captive spring peepers can eat all the food they would eat in the wild. The only reason they will have a different diet is that it is not easy to obtain the wide variety of prey these frogs eat in the wild.

So most people are limited to only prey items they can purchase or culture on their own.

What adult spring peepers eat in captivity

However, even in captivity, it’s a good idea to keep the frog’s diet as close to its wild diet as possible. This means you have to feed it live prey.

Most frogs will readily accept crickets and worms. It is recommended to gut load the crickets to make them more nutritious (more information on that is below).

Here’s a list of things you can feed a spring peeper in captivity:

  • Pinhead crickets, newly hatched roaches,  flightless fruitflies
  • Dwarf white Isopods, springtails
  • Small silkworms & hornworms
  • Small mealworms
  • Small Nightcrawlers

Most tree frogs are not very picky eaters and will readily accept most soft-bodied invertebrates. Crickets can make up a majority of their diet. However, the key to a healthy frog is a varied and nutritious diet, so remember to switch up the food items offered every few feedings.

IT IS NOT RECOMMENDED to feed red wigglers (Eisenia fetida) to captive frogs. This is because they exude a noxious fluid that contains a toxin known as Lysenin – which is poisonous to many animals.

Since these worms are foul-tasting, some frogs will actively spit them out instead of swallowing them. If the frog somehow accepts the worms, it may be harmed by their toxins.

If you want to feed your frog mealworms, it’s a good idea to only use the ones that have just shed, and still have soft bodies, as the hard exoskeleton of mature mealworms is very hard for gray tree frogs to digest.

As for fruit flies, it’s recommended to use Hydei fruit flies as they are considerably bigger than the Melanogaster fruit flies and make a richer meal for your frog.

Gut-Loading & Nutrient Supplements

Captive-bred feeder insects are often raised on a cost-conscious diet that is meant to help them grow quickly. This means they are not as nutritious as wild insects that eat a wide variety of vitamin and mineral-rich food.

If your frog is given a low-nutrient diet, it could develop health problems such as Metabolic bone disease which is a fairly common issue in captive amphibians.

For this reason, it is important to increase the nutritional value of the food you give to your frog.

Gut Loading

Gut loading is the process by which feeder insects are fed nutrient-dense foods at least 48 hrs before they are offered to the frog. The intention is to pass those nutrients on to the frog when the insects are eaten. 

The process is simple

  • Give your feeder insects nutrient-dense foods, such as fresh vegetables with lots of vitamin C.
  • After eating this food, the feeder insect will be much more nutritious and pass the nutrients on to the frog when they are eaten.

Dusting

Besides gut loading, another way to ensure your frog gets all the vitamins and minerals it needs is by dusting its food with high-quality powder calcium and vitamin supplements.

Most hobbyists use commercially manufactured supplement powder specifically designed for reptiles and amphibians.

The process is simple:

  • First, add a small pinch of supplement powder into a small container such as a cup or an empty cereal container. The powder should only be enough to lightly dust the insects.
  • Place one feeding’s worth of feeder insects in the container
  • Gently shake the container so the supplements lightly coat the insects
  • Once finished, you can offer the dusted insects to your frog

It’s a good idea to alternate between a calcium a multi-vitamin powder. If you dust with a calcium powder, next time remember to dust with a multi-vitamin powder instead, and vice-versa.

Occasionally skipping a dusting or gut load is fine. But make sure to dust or gut load the feeder insects the majority of the time.

How Much & How Often to Feed Your Spring Peeper

In general, most frogs need to be fed about two to three times a week. However, as ectothermic (cold-blooded) animals, the temperature will influence the feeding frequency.

They will generally have an increased appetite at higher temperatures and a reduced appetite when the temperatures are lower.

Regarding how much to feed your spring peeper, the general rule is to only offer it as much as it can eat in a single 20-minute feeding session.

Most frogs will stop eating when they have had their fill, so this can be learned with a little bit of experimentation. Use personal judgment to ensure most of the food offered is being consumed.

Also, avoid leaving uneaten bugs in the frog’s enclosure for too long as they could bite or irritate the frog. Remove all uneaten food within 4 – 6 hours of feeding.

What Human Foods Can a Spring Peeper Eat?

Adult spring peepers are obligate carnivores that are instinctively attracted to movement while hunting for food. For this reason, they will not eat the vast majority of human food.

Humans do not typically eat live food and tend to cook most of their food, so human food will not even register as food to most frogs, including spring peepers. If you try to offer human food to a spring peeper, it will not eat it.

How to Feed a Spring Peeper in Captivity

The easiest way to feed a captive frog is to simply dump the food into its enclosure and let the frog have its fill.

However, some frogs, especially those that are still getting used to a new place may be shy and reluctant to eat. In this case, you could entice the frog to eat with the use of some feeding tongs.

Use the tongs to gently hold the food item, then rub it near the nose of the frog. Once he sees it, he will grab it and do the rest.

Common Feeding Mistakes

There are a few common mistakes many new frog owners make when feeding their pets.

Using Dead Bugs

In the wild, frogs are ambush hunters that are attracted to prey by movement (motion). For this reason, spring peepers won’t eat dead bugs. If you offer your spring peeper dead bugs, it will most likely ignore the food and starve. You should only offer live bugs and other prey items.

Using the Wrong-Sized Feeder Insects

Frogs do not chew their food but rather swallow it whole. Feeding a tiny frog a disproportionately large insect could lead it to choke.

Never give a frog anything larger than the distance between its eyes. The bigger the frog, the larger the prey it will be able to eat.

Forgetting to Gut Load Insects

As mentioned earlier, captive-bred feeder insects do not contain as many nutrients as wild insects. They are often raised on a cost-conscious diet that is aimed at making them grow quickly and keeping costs low.

Forgetting to gut load or dust insects before feeding them to your spring peeper means the frog will not get all the nutrients it needs. This nutritional deficiency can lead to serious health problems, and could even be fatal.

Not Using a Varied Diet

Different food items have different nutrients. Not giving a spring peeper a varied diet means it will not get the right variety of nutrients it needs and may end up weak and malnourished.

Switch up the food items offered to the frog every few feedings so it gets a nutrient-rich diet.

Feeding Food With a High-Fat Content Too Often

Captive frogs are not very active animals, so they do not burn off calories. This means giving a captive spring peeper high-fat food (such as wax worms) too often may lead to obesity.

Obesity can then lead to many health problems. For this reason, it is important to limit food with a high-fat content to only an occasional treat.

Overfeeding/ Underfeeding

Frogs have huge appetites, so overfeeding is a real possibility. Obesity could lead to several health problems. Alternatively, underfeeding means the frog will be undernourished and have poor health.

Common Questions About Spring Peeper Diet

Do spring peepers eat mosquitoes? Spring peepers regularly eat mosquitoes in the wild. A single spring peeper can eat hundreds of mosquitoes in a month – helping control these pests without the need for pesticides.

What do feed spring peepers? In the wild, spring peepers choose food by availability and size than by actual preference. Most spring peepers will readily accept pinhead cricks, small worms, and other small soft-bodied invertebrates.

What do baby spring peepers eat? Spring peepers start as tadpoles that eat algae, soft plants, and small invertebrates. Over time, the tadpoles will transform into froglets that are obligate carnivores. Once transformed, baby spring peepers will eat ants, mites, termites, crane flies, and other small insects.

Can you keep spring peepers as pets? Spring peepers can be kept as pets, but they are not very common pets. Most people who keep spring peepers as pets are hobbyists, who deliberately seek them out.

Spring peepers are small, slender tree frogs found throughout much of the eastern part of North America. These frogs can be easily identified by their tan or light brown coloration with a dark X-shaped marking on their back. But are spring peepers poisonous?

Spring peeper frogs are not poisonous. They do not produce any skin toxins and are generally harmless to humans, dogs, cats, or any other pets. The only real threat they pose is that, like many amphibians, they can be carriers of salmonella bacteria, which can be harmful to humans, or pets.

Spring peepers are otherwise harmless creatures. Just practice a sufficient level of hygiene (such as washing your hands after handling any spring peepers), and you will be fine.

Spring Peepers Do Not Produce Skin Toxins

Unlike many frogs (such as gray tree frogs or pickerel frogs), spring peepers cannot produce skin toxins to defend themselves. For this reason, these frogs are preyed on by many birds, snakes, raccoons, large spiders, and even larger amphibians.

However, this does not mean spring peepers are defenseless when it comes to fending off predators. They have other ways to protect themselves.

Spring Peepers Do Not Have Venom

If you are like most people, you have probably (at least once) used the words “venomous” and “poisonous” interchangeably. But you should know that there is a significant difference between these two terms.

Sure, they both refer to toxins that could be harmful to us, but the difference lies in how these toxins are delivered.

Generally;

  • Venom is actively injected, usually through stings, fangs, or barbs (think rattlesnakes, scorpions).
  • Poison on the other hand is delivered much more passively and has to be absorbed/ingested into your body. It can be ingested when it comes into contact with your eyes, lips, mucus lining of the nose, or open cuts on your skin (think poison dart frogs).

In other words, if an animal has to bite or sting you to inject its toxins it is venomous. If an animal secretes its toxins on its skin, then you can ingest those toxins when you eat, lick or touch the animal, it is poisonous.

Poisonous frogs can not inject venom using their teeth

Spring peepers do not secrete toxins on their skin and neither do they have the ability to inject any toxins. For this reason, they are not venomous or poisonous.

How Do Spring Peepers Defend Themselves?

Since spring peepers do not have any toxins, they may seem defenseless when it comes to fending off hungry predators. However, they have a few tricks to keep predators away.

As the first line of defense, spring peepers have an inconspicuous coloration that helps them blend into the leaves and other debris in their environments, escaping the notice of most predators.

However, sometimes camouflage alone is not enough, so spring peepers are also very strong jumpers. If they see a predator getting too close, they can use their powerful hind legs to leap a distance of up to 17.5 inches and escape.

One study observed several species of frogs and found that spring peepers had the least degradation of performance in repeated jumps. This means they can repeatedly leap large distances to slip away from predators.

Are Spring Peepers Dangerous to Humans?

Since spring peepers do not secrete any toxins, they are generally harmless to humans. That being said, it is important to note that almost all frogs can carry salmonella bacteria, which can be harmful to humans.

Spring peepers can carry salmonella bacteria in their digestive tract and excrete it in their waste. The bacteria do not cause any illness in the frog – so a spring peeper carrying salmonella bacteria can look clean and healthy, but the bacteria can be transmitted to humans.

Salmonella-sp.-bacteria.
Salmonella-sp.-bacteria.

Humans can be exposed to salmonella by direct or indirect contact with a frog, its waste, or anything the frog came in contact with. (For example, you touch a spring peeper or its droppings, then stick your fingers into your mouth without first washing your hands).

Exposure to salmonella can cause an infection called Salmonellosis which is characterized by stomach cramps, diarrhea, fever, nausea, and sometimes vomiting.

Most infections only cause mild illness, but sometimes, the bacteria can spread to the bloodstream leading to serious illness.

Fortunately, merely touching a spring peeper frog will not give you a salmonella infection. The bacteria can only cause illness when they are ingested. Therefore, thoroughly washing your hands immediately after touching any spring peepers should keep you out of harm’s way.

It is not a good idea to let children under the age of five or people with weakened immune systems handle any amphibians. This is because they are at higher risk of getting a salmonella infection. Children, in particular, tend to stick their fingers in their mouths much more frequently than adults. Doing this after handling a frog could make a child very ill.

Are Spring Peepers Poisonous to Dogs, or Cats?

Spring peepers do not have any toxins so they are typically harmless to dogs, cats, or other pets, even if eaten.

However, as mentioned earlier, all frogs can carry salmonella bacteria so a dog or cat that mouths, bites or eats a spring peeper may consume the bacteria and develop an infection.

Also, frogs can carry tapeworms and other parasites. This means if a dog eats a spring peeper, it may also consume parasites and develop a parasitic infection.

For this reason, it’s a good idea to keep your pets away from any frogs, even if they are not toxic.

It is extremely rare for healthy dogs or cats to get a salmonella infection. This is because they have very strong stomach acids that kill the bacteria before they can cause any illness. Still, even if the pets don’t show symptoms of salmonellosis, they can shed and spread the bacteria to humans.

Safety Precautions to Take When Handling Spring Peepers

Generally, it is not a good idea to handle amphibians. This is because they have very sensitive permeable skin that absorbs water and other substances it comes in contact with.

If you touch a frog, – salts, oils, lotions, perfumes, repellents, and other substances on your hands can be absorbed right through its skin, and hurt, or even potentially kill the frog.

For this reason, it’s advisable to observe frogs from a distance without physically touching them.

If you ever need to handle a spring peeper frog (such as moving it out of harm’s way), take the following precautions to protect both you and the animal.

Before Handling
  • Wash your hands EXTREMELY so they are very clean. Not just clean from dirt, but from perfumes, lotions, or any other substances that could harm the frog, and be sure that no soap residue remains on your hands.
  • After washing your hands, dry them (preferably with paper towels), then re-moisten with dechlorinated water.

Even better, you could wear protective gloves (powder-free vinyl gloves or nitrile gloves).

Wearing gloves will not only prevent you from coming in contact with bacteria that may be on the frogs’ skin but will also protect the frog from harmful substances you may have on your hands.

The gloves also have to be moistened with dechlorinated water.

When Handling
  • Keep the frog away from your eyes, nose, and mouth and, be very careful not to rub your eyes, or touch your nose, or mouth.
  • As you handle the frog, do it very gently and with care so you do not injure or stress the toad in any way. Avoid squeezing the frog too hard, or applying too much pressure on it.

Frogs should only be handled for a short time. Handling a frog too long can cause stress to the animal and dry out its skin.

What to Do After Handling
  • Very thoroughly wash your hands with anti-bacterial soap under running water.

Even if you were wearing gloves, it is still a good idea to go the extra mile by washing your hands. As earlier mentioned, spring peepers may carry bacteria that can be harmful, so it’s best to protect yourself.

Before washing your hands, do not touch anything (you could spread bacteria) – and remember not to rub your eyes, touch your face, or put anything into your mouth.
