If you’ve ever had a cockroach problem, you know how annoying they can be. They’re fast, hard to catch, and seem to appear out of nowhere. You might also notice geckos around your home and wonder if they could help with your roaches. Do geckos eat cockroaches?
Yes, geckos eat cockroaches, and many love them. Cockroaches are a high-protein, easy-to-catch meal for geckos, both in the wild and in captivity. Pet geckos often enjoy small roaches like dubia roaches, which are safe and nutritious. Bigger wild cockroaches are fair game too, but geckos usually go for ones they can easily handle and swallow.
Why Geckos Like Cockroaches
Cockroaches are an ideal snack for geckos for a few reasons.
First, they’re full of protein and fat, which geckos need for energy and growth. Roaches give great nutrition for insect-eating lizards.
Cockroaches are also the right size for most geckos. Small and medium roaches are easy to catch and swallow, and even baby cockroaches, called nymphs, make perfect snacks for smaller geckos.
Both geckos and cockroaches are most active at night. This means geckos are awake and hunting exactly when roaches come out looking for food. It’s a perfect timing match.
Roaches also move in ways that trigger a gecko’s hunting instinct. A scurrying roach is an instant target for a gecko.
Which Geckos Eat Cockroaches?
Most geckos will eat cockroaches if they can.
House geckos, common in tropical and subtropical areas, are excellent roach hunters. They’re small enough to slip into tight spots where roaches hide and fast enough to catch them.
Tokay geckos are bigger and can handle larger roaches. They’re aggressive hunters and won’t hesitate to take on big roaches.
Leopard geckos, popular as pets, also eat cockroaches. Many owners feed them dubia roaches as a main food because they’re nutritious and easy to digest.
Mediterranean geckos, another common house dweller, naturally hunt roaches along with flies, moths, and other bugs.
Even smaller gecko species will eat baby roaches. Very few geckos will turn down a roach that’s the right size.
How Geckos Hunt Cockroaches
Watching a gecko hunt is really interesting. They combine patience, speed, and precision.
Geckos hunt mostly by sight and movement. When a gecko spots a roach, it freezes and studies it. Then it moves slowly and quietly toward the target, trying not to alert it.
Once close enough, the gecko strikes fast. In a flash, it snaps its jaws around the roach. The attack is so quick the roach barely reacts.
Small roaches get swallowed whole. Bigger ones might need a few bites or repositioning before going down. Either way, the meal is over in seconds.
Can Geckos Control a Cockroach Infestation?
Geckos eat roaches, but they have limits.
A single gecko can eat several roaches a night, which helps reduce numbers. But if you have hundreds or thousands of roaches, one or two geckos won’t solve the problem by themselves.
Geckos are best for preventing problems and controlling small roach populations. They work well as part of a bigger pest plan, not the only solution.
In many tropical countries, people welcome geckos into their homes because they help keep roach numbers down. Geckos won’t get rid of all the roaches, but they can keep the population manageable.
For serious infestations, you’ll still need traps, baits, and cleanliness. But geckos are a great natural backup.
Are Cockroaches Safe for Geckos?
For the most part, yes.
Wild roaches that geckos catch in your home are usually safe and healthy. They’re part of a gecko’s natural diet.
The main risk is pesticides. If roaches have been exposed to insecticides, a gecko that eats them can get poisoned. This is called secondary poisoning, and it can make geckos very sick or even kill them.
If you want geckos to help with roach control, avoid chemical sprays. Use traps or natural deterrents that won’t harm the geckos.
For pet geckos, store-bought roaches like dubia or discoid roaches are safe, free from pesticides, and parasite-free.
What Size Roaches Can Geckos Eat?
It depends on the gecko’s size.
A simple rule: prey should be no wider than the distance between a gecko’s eyes. This keeps swallowing safe.
Small house geckos can eat baby roaches and small adults. They avoid big roaches because they’re too much to handle.
Medium geckos like leopard geckos can eat medium to large roaches. Their jaws are strong enough for bigger prey.
Large geckos like tokays can eat huge roaches. Their strong jaws can crush them, and they can swallow surprisingly big prey.
If a roach is too big, most geckos ignore it and look for smaller prey. They know their limits.
Do Pet Geckos Need Roaches?
Cockroaches can be an excellent part of a pet gecko’s diet.
Many owners feed dubia roaches. They’re nutritious, with good calcium balance, and easy to digest.
Roaches are meatier than crickets, so one or two can make a full meal. They’re also quieter and less smelly, making them easier to keep.
Variety is still important. Mix in crickets, mealworms, or waxworms for a balanced diet.
Always gut-load feeder roaches before feeding. Feed them nutritious food for 24 hours so your gecko gets the full benefit.
Benefits of Geckos for Pest Control
Geckos do more than just eat roaches.
- They’re safe around your home. Unlike chemical sprays, they don’t leave residue or hurt kids or pets.
- Geckos work 24/7. They hunt all night without you doing anything.
- They eat other insects too: mosquitoes, flies, moths, and ants. One gecko helps control many pests.
- Geckos can be a sign of a healthy home ecosystem. They only stick around where there’s enough food, so if they live in your home, they’re finding pests you might not notice.
- Geckos are quiet, clean, and stay out of your way. You might barely notice them, except when you see them hunting.
How to Attract Geckos
If you want geckos to help with roaches:
-
Don’t use pesticides. Let bugs survive so geckos have food.
-
Give hiding spots. Leave small gaps or cracks for geckos to feel safe.
-
Keep lights on at night near windows. Bugs go to light, and geckos follow.
-
Provide water. A shallow dish or damp areas works.
-
Don’t try to catch or harm geckos. Make your home a safe space.
Once geckos feel safe, they’ll stick around and hunt for you.
Conclusion
Geckos eat cockroaches and are great at it. They’re natural hunters that help keep roach numbers down.
They won’t fix a huge infestation alone, but as part of a pest plan, they’re amazing. They hunt all night, don’t use chemicals, and eat many other pests too.
If you see geckos in your home, let them do their job. They’re on your side, working hard every night, turning your cockroaches into dinner.
