What Eats Cockroaches | List of 10 Cockroach Predators

Cockroaches are a relatively peaceful pest.

For the most part, they’re happy to just live inside the human home and aren’t known to bite very often; they can bite humans, but that rarely happens.

Cockroaches, however, are still on the food chain, which means that they have predators and animals who wish to have them as a tasty snack; some animals even eat roaches as part of their everyday diet and routine.

So which are these natural predators that can relish and enjoy roaches while we dread their existence?

Let’s find out

Does Anything Eat Cockroaches?

Cockroaches can be a healthy and full protein diet for some animals that feed on roaches regularly.

Cockroaches have many natural predators like spiders, frogs, geckos, and many others.

Some parasitic species of wasp also target roaches; these species lay their eggs inside the egg case of cockroaches; hatchlings feed upon nearby cockroach eggs.

Though these species are hated by many, but, still can be a proper food for some animals; the animals that prey regularly on cockroaches are:

  • Toads and frogs
  • Lizards
  • Certain large species of beetles
  • Certain kinds of parasitoid wasps
  • Entomopathogenic fungi

These predators have their own way of preying on the cockroaches.

Toads, frogs, and lizards can reach out to them with their long and sticky tongues, while, wasps often lay their eggs within adult cockroaches and larvae.

When the wasp eggs hatch, they will feed on the roach, destroying them even before they have any chance.

Like this, different insects have their own way of preying on cockroaches and eat them.

Why Animals Eat Cockroaches?

Benefits of eating roaches

Though roaches are considered the most hated species; these insects have their own nutritional value too.

Some insects that regularly prey on the roaches get really expensive and rich in protein; even human beings have started to prey on these insects because of their nutritional value and rich protein substitutes.

Roaches can be considered a way to provide proteins, and that’s why many animals prefer eating roaches instead of other insects.

So, What Eats Cockroaches?

Cockroaches have several natural predators to look out for; some cockroach predators include toads and frogs, beetles, iguanas, geckos, and certain types of wasps.

Each predator has its own unique way of catching the cockroaches- toads and frogs use their sticky tongues to grab them and then their strong toothless jaws to crush them; parasitic wasps, on the other hand, use a more aggressive tactic.

They will lay their eggs inside adult cockroaches and their larvae; when the wasp’s eggs hatch, they will begin to feast on the cockroach or its larvae.

This slowly destroys cockroach larvae before they have a chance to hatch and causes a slow and painful death for adult roaches.

Lizards like geckos and iguanas are commonly kept as pets, often after cockroaches as part of their diet; they are inexpensive and nutritious for these types of lizards.

Natural Predators of Cockroaches

A general understanding among the reptile pet owner community that a lizard can be fed cockroaches is the size of the length between the lizard’s eyes.

Some household lizards can eat as many as 20 cockroaches at a time; if you’ve spotted small baby roaches in your house, they can also be an easy target for lizards.

Although uncommon, some cats may find cockroaches to be a good snack, as well; indoor cats that happen to find a cockroach in their area will often stalk, play, and then eat the roach.

This practice may be unsettling to pet owners and could cause worry- what if the cat gets sick? Are the roaches harmful?

However, cockroaches are safe for felines to eat.

In fact, the act of catching the cockroaches can be good for the cat’s health; it helps the cat to exercise his or her natural hunting instincts by allowing them to chase, catch, and kill a form of prey.

Cockroaches are also full of nutrients that can be beneficial to your cat’s overall health; it isn’t recommended to allow your feline friend to eat their fill of cockroaches, though.

Mice have been known to eat roaches on rare occasions; if a mouse finds a dead cockroach and happens to be searching for food, it may eat the roach as it is an easy meal, even if it isn’t a highly preferred dish.

Pet owners who keep mice should avoid allowing their pet mouse to eat roaches that come in from outside; however, wild cockroaches can contain dangerous parasites that could harm a domesticated mouse.

Birds also eat roaches, but this is very rare; some bird owners will feed their birds cockroaches. This isn’t recommended as it can be dangerous for birds to eat this type of insect.

Only experienced bird owners should attempt to use cockroaches as a meal for their bird, but even they should be avoiding it.

Some species of ants will snack on roaches; the Red imported fire ant (RIFA) is one such species, Argentine ants (also known as black sugar ants).

Ants will usually only eat the bodies of dead cockroaches drying up or decaying, as they are scavengers and not hunters.

Hedgehogs may or may not eat cockroaches; if a hedgehog finds a cockroach and can catch it, the hedgehog could turn it into a snack.

Like with mice, hedgehogs that are domesticated and kept as pets shouldn’t be allowed to eat roaches that have come in from outside.
