House crickets are drawn to warm moist environments, seeking food and shelter within homes and structures as temperatures cool down in the fall..

House Cricket Habitat

During warm weather, the house cricket lives outdoors in piles of debris, rocks, firewood and lumber. They may also be seen in compost bins and garbage dumps during the winter, as well as in houses, sheds, and other shelters. With the coming of cold weather, the house cricket enters homes and is active in warm areas of the house. House crickets are nocturnal and usually first make themselves evident at dusk when they begin to seek food in homes. Homeowners may also be alerted to their presence by the familiar chirping sounds made by males. When attracting females, males rub their front wings together causing a chirping sound.

House Cricket Behaviors, Threats or Dangers

House crickets do not bite or spread disease, however, they can become a nuisance if they gain entry into a home, damaging clothing, carpets and areas covered in fabric. Because these crickets are attracted to warmth, they are often present in the vicinity of the fireplace, kitchen, furnace, water heater and basement. They conceal themselves in cracks, behind baseboards and may burrow into the mortar of walls. The house cricket is especially destructive to silk and woolens.
