Jerusalem Crickets
Appearance:
Jerusalem crickets (Stenopelmatus fuscus) are large insects, distinct for their striped dark brown bands across their body. Their head is notably massive and cream-yellow underneath, giving them a unique appearance often described as “baby-faced.” These wingless crickets have spiny legs and strong jaws, but despite their intimidating look, they are generally harmless.
Biology
These crickets are much larger than house or field crickets. They are nocturnal and thrive in dark, moist environments. You’ll commonly find them hiding under stones, logs, bricks, or boards during the day. They come out at night in search of food, primarily feeding on decaying plant and animal matter, as well as root crops like potatoes and radishes, which earns them the nickname “potato bugs.”
Mating occurs in the spring, after which females lay small masses of eggs in the soil. These crickets are not typically household pests, but they may wander inside homes occasionally.
Jerusalem Cricket Control
While these insects don’t pose serious threats to your home, they can be a nuisance. Control measures are relatively simple. Ensure that garden debris, rocks, and logs are properly cleared to reduce hiding places. In agricultural settings, crop rotation and soil health management can minimize their impact on root crops. If they enter your home, sealing cracks and gaps in walls or foundations will help prevent indoor encounters.
Treating can be effectively done using a residual granular insecticide, such as Talstar PL Granules. These granules can be applied to areas where crickets are commonly found, like garden beds, beneath rocks, and other outdoor hiding spots. The slow-release formula provides long-lasting protection, ensuring that the crickets are killed on contact and future infestations are controlled. Many granular insecticide products, including Talstar PL, are safe for use around edible gardens, so you can protect your plants and crops while keeping pests at bay. Always follow the product label for application instructions.
For severe infestations or to avoid potential bites, professional pest control services may be necessary.
