Crickets Behavior & Habits

Understanding how crickets behave helps prevent infestations

Signs You Have Crickets

What homeowners spot first

  1. Chirping sounds at night
  2. Jumping insects near lights
  3. Chewed fabric or paper
  4. Dead crickets on floors and windowsills
  5. Cricket droppings (small black pellets)

Male crickets chirp by rubbing their wings together to attract mates. They're nocturnal and attracted to lights. Crickets eat plant material and occasionally fabric, paper, or other organic materials. Large populations can become a nuisance with constant chirping.

Crickets in Boise & the Treasure Valley

Cricket calls in the Treasure Valley pile up from August through October, once nights cool and porch lights start pulling them up to the house. The garage door bottom seal is the #1 entry point we find, with siding gaps under exterior fixtures a close second. We see the heaviest pressure in rural-edge neighborhoods like Kuna, Star, Middleton, and west Caldwell where homes back up to fields, and around golf-course communities on the Eagle and south Meridian sides. Mormon crickets occasionally swarm elsewhere in Idaho, but we rarely see them in the Valley.

Our Solution

How We Eliminate Crickets

Professional treatment for complete elimination

We hit the exterior perimeter to stop crickets at the wall, treat harborage spots like landscape beds and the garage door track, and clean up any indoor stragglers. Most homeowners see results in 24-48 hours, and we'll point out the porch lights or door sweeps that are pulling them in. Your first visit is $49 with quarterly service.

FAQ

Crickets Questions Answered

Common questions about identification, prevention, and treatment

Why do crickets chirp at night?

Male crickets chirp to attract females, and the chirping speeds up as it warms outside. You can actually estimate the temperature from a cricket: count chirps in 14 seconds and add 40 for a rough Fahrenheit reading.

How do I stop the chirping?

Find and remove the cricket (they're often near the sound source) or treat infested areas. Reducing outdoor populations through perimeter treatment prevents them from entering. A single cricket can be nearly impossible to locate by sound alone.

Do crickets cause damage?

Large populations can damage fabrics (especially with perspiration stains), paper, and some food items. A few crickets cause minimal damage. The main issue is usually the noise, not damage.
