The answer to 'types of cricket' is there are several common types of crickets that can become pests in homes. The most common are house crickets, field crickets, and camel crickets.
House crickets are the most well-known and commonly found indoor crickets. They are light brown in color, about 1 inch long, and often found around warm, moist areas like kitchens and bathrooms. Field crickets are larger, up to 1.5 inches, and are black or dark brown. They typically live outdoors but may wander inside. Camel crickets are hump-backed, light brown, and prefer damp, dark areas like basements and crawl spaces.
