Crickets may be considered a nuisance because of their constant chirping; however, none of our species are likely to bite or carry diseases.
The Indian house cricket (Gryllodes supplicans) feeds on a wide range of food sources and can damage fabrics, leaving the surface roughened from pulling or picking the fibers loose while feeding. It is light yellowish/brown or tan in color with darker bands and spots, and about 1 inch long when mature; these are very common crickets in many states. They often gather around foundations and doors outside and readily come indoors through cracks or openings. They are the only type of cricket that live and produce young indoors. They typically hide during the day and come out at night to feed on crumbs, pet food, and plant debris.
The Field cricket (Gryllus spp)is larger than the Indian house crickets (slightly more than 1 inch when mature) and usually dark brown to shiny black in color. Field crickets also enter houses and buildings. These crickets prefer to live and breed outdoors where they feed on several kinds of plants. Occasionally they invade homes in search of hiding places but do not produce young indoors. Field crickets are known to chew on and damage wool, cotton, silk, synthetic fabric, fur and carpeting. Clothes with perspiration stains or food spills are particularly attractive. Outdoors, they may damage young garden plants and annual flowers.
Camel crickets (Ceuthophilus spp.) are not a problem in every state. They have long antennae and significantly larger hind legs than other crickets. Tan to dark brown in color, wingless, and with a humpedback (giving them their name). These crickets do not chirp. They are found outside in caves, wells, hollow trees and stumps, and under rotten logs, damp leaves, stones, boards and bricks. May wander indoors as an accidental invader; in rare cases it will breed in moist dark areas, such as basements.
