How to identify and get rid of Jerusalem crickets

Even though they aren’t from Jerusalem and they aren’t a cricket, Jerusalem crickets are fascinating insects to stumble across.

First off, they are big and hefty, sometimes weighing more than a small mouse. Second, they seem to unexpectedly come out of the ground at night.

Despite their somewhat intimidating look, Jerusalem crickets are mostly harmless and tend to keep to themselves, living quietly below the soil surface.

These nocturnal creatures are more commonly observed when they accidentally wander into homes or are unearthed while gardening. Their large size and human-like head often cause unease, yet they play a beneficial role in the ecosystem by breaking down organic matter.

Jerusalem crickets are wingless, so they can’t travel very far to find a mate. When they emerge from the ground, the female strums her abdomen on a hard substrate, creating a distinct rhythm and pattern that the males respond to. The males will then call back and eventually, they find each other.

Jerusalem crickets can be identified by their large, wingless bodies and distinctive heads. They have small eyes and antennae, but powerful jaws. These insects are generally yellow to brown and have a heavy, cylindrical form that sets them apart from other garden pests. They have strong legs well-suited for their burrowing lifestyle. While they're not common household pests, their presence inside homes usually indicates an accidental wandering from their natural soil habitat.

How big are Jerusalem crickets?

Some species of Jerusalem crickets can grow to about 3 inches long.

Jerusalem crickets are found primarily in the western United States, thriving in arid and semi-arid climates where the soil is loose and easy to burrow.

Jerusalem crickets aren’t usually considered a major pest for homeowners or gardeners. However, if the conditions are right, you may get a few that wander into your home. If you are concerned about Jerusalem crickets getting too comfortable inside your house, consider these ways to keep them out:

Reduce moisture: Eliminate damp areas around your home to make environments less inviting.

Physical barriers: Seal cracks and crevices in the foundation and along the walls to prevent entry.

Remove shelter: Clear away debris, piles of wood, and rocks where they might seek shelter.

Proper soil management: Maintain a well-aerated and dry garden to discourage them from moving closer to your home.

Bug barrier: Consider creating and maintaining a bug barrier around your home to prevent any Jerusalem crickets from wandering inside.
