Crickets in Valley homes

Field crickets are the loud chirping you hear on a warm Valley night, and Jerusalem crickets are the large, startling, wingless bug with the almost human looking face that turns up digging in damp soil. Neither is dangerous, but both can show up in heavy numbers around exterior lighting and damp mulch beds.

  4. 4Don't handle a Jerusalem cricket bare handed, they can pinch
What we do about it

How Facility handles crickets

We treat the perimeter to label to cut down crickets working their way toward the house and can recommend simple lighting changes, warm or yellow bulbs draw far fewer insects than bright white ones, that make a real difference on their own. This is handled as part of general pest service rather than a separate visit.

Crickets questions

What's making that loud chirping noise at night?

That's almost always field crickets, the chirping is males rubbing their wings together to attract females, and it gets loudest right at dusk through the evening in late summer and fall. A single cricket in a wall void can sound surprisingly loud from inside a quiet room at night.

What is that big bug with the human looking face in my yard?

That's a Jerusalem cricket, a large, wingless insect with a striped abdomen that spends most of its time underground and only turns up on the surface occasionally, usually after digging or watering disturbs it. It looks alarming but is not a dangerous pest, just a startling one to find under a pot or paver.

Do Jerusalem crickets bite?

They can pinch with strong mandibles if handled, and it can be uncomfortable, but they're not venomous and not considered dangerous to people. The safest approach is simply not picking one up bare handed, they're slow moving and easy to avoid without needing to touch them at all.

Why are crickets swarming my porch light?

Crickets and many other night flying insects are drawn to bright white light, and a porch light left on becomes a gathering point for the whole yard. Switching to a warm or yellow toned bulb draws noticeably fewer insects overall and is one of the easiest fixes available.

How do I stop crickets from getting inside?

Seal gaps under exterior doors, since crickets can walk straight through a gap that looks too small to matter, and keep mulch and debris pulled back a few inches from the foundation. Switching exterior lighting to warm toned bulbs also cuts down how many gather near entry points in the first place.
