House crickets, scientifically known as Acheta domesticus, are small, nocturnal insects that often find their way into homes. Known for their distinctive chirping sound, house crickets are common across the United States and can become a nuisance if they invade in large numbers. Read on to learn more about how to identify house crickets and where you’re most likely to find them.
House crickets are small insects, typically light brown, with three dark bands on their heads. Their average size ranges from 0.5 to 1 inch. Equipped with strong hind legs, house crickets are excellent jumpers and are often seen hopping around indoors or outdoors.
These crickets are nocturnal, meaning they are most active during the night. One of their defining traits is their loud chirping, produced by rubbing their wings together—a behavior used by males to attract females.

House crickets go through three stages: egg, nymph, and adult. Their life cycle lasts two to three months, depending on the temperature, and they do best in warm conditions. Males chirp to attract females, and after mating, females lay up to 200 eggs in damp areas.
The eggs hatch into nymphs, which look like small adult crickets but don’t have wings. Nymphs molt (shed their skin) several times as they grow, and after about a month, they start to grow wings. Once fully grown, adult crickets focus on eating and mating, and the cycle starts again.
House crickets are small, light brown insects, usually about 0.5 to one inch long. They have three dark bands on their heads, long antennae, and long, slender legs that help them jump. Their wings are short when they’re young but fully developed when they’re adults. House crickets are known for their loud chirping, which they make by rubbing their wings together.
House crickets thrive in warm, moist areas, such as basements, kitchens, and crawl spaces. Outside, they are commonly found in piles of firewood, compost, and debris. During cold weather, they often seek shelter indoors to escape the drop in temperature.
House crickets are common throughout the United States, particularly in urban and suburban areas. While they prefer warmer climates, they can survive in colder regions by taking refuge inside homes. The presence of these insects is more noticeable during late summer and fall when they actively seek indoor shelter.
Are house crickets bad to have in your house? While house crickets are not dangerous to humans, they can be a nuisance. Their loud chirping can disrupt sleep, especially in areas with significant infestations.
In addition to their noise, house crickets may damage fabrics, such as clothing, curtains, and upholstery. They are known to chew on these materials, leaving behind irregular holes. While house crickets do not bite humans, their presence in large numbers can lead to property damage and discomfort.
Getting rid of house crickets can be challenging, especially if they have established a cricket infestation in hidden areas of your home. These nocturnal insects are adept at hiding in cracks, crevices, and other hard-to-reach places.
Effective cricket control often involves eliminating moisture sources, sealing entry points, and removing potential hiding spots. Our cricket experts at Ehrlich can help identify and treat infestations to prevent crickets from returning.
