House crickets are small insects commonly found in homes, especially in warm areas. They have a brownish color and can grow up to 1 inch long. These crickets are known for their distinctive chirping sound, which is produced by males to attract females. House crickets thrive in dark, humid environments and often hide in basements, kitchens, and around food sources. They are omnivorous, feeding on a variety of organic materials, including grains and fabrics. While they are not harmful, their presence can be a nuisance, and they can sometimes damage household items.
