Brown House Cricket

In the wild, these omnivorous crickets can have a varied diet, including fruits, seeds, leaves, grass, and small insects. They can even eat the remains of other dead house crickets. So, their pet diet mainly comprises fruits, vegetables, and food grains.

When nesting in houses as pests, they will eat anything they can find, from pet food to fabric, carpet, and wool.

These crickets do not hibernate or have any particular overwintering stage. They take shelter inside buildings or in dumps and debris to survive the cold season, using the heat from their fermentation process. 

Life Cycle

Their reproduction happens in temperatures between 79°F and 90°F. The females lay their eggs in any damp substrate, including moss, wet sand, and moist areas in or around houses. Their life cycle, from eggs to nymph to adult, takes around 2-3 months to complete.

Getting Rid of House Crickets

Common House Cricket

Like any pests, getting rid of house crickets is not easy.

Application of boric acid and commercial cricket treatments or using sticky glue traps may help.

It is essential to wash hands with soap after handling house crickets or their nest material as they may carry parasitic diseases like salmonella and E. coli.
