House crickets are larger Orthopteran insects that are related to bush crickets and grasshoppers. They generally grow to an inch long and have a mix of yellow and brown color on their bodies. However, their primary identifying characteristic is the large and long bent leg with spotted markings on the body. While a cricket bite doesn't puncture the skin of a human or cause physical harm, they have been proven to carry a significant number of diseases that might be harmful to humans and cause sores, skin irritation, and other complications.
