House Crickets
Acheta domesticus
House crickets are light brown to tan insects measuring 3/4 to 7/8 inch long with three dark bands across their heads and long antennae. Males produce the distinctive chirping sound by rubbing their wings together to attract females. These nocturnal insects are strong jumpers and can become significant nuisance pests when they enter homes in large numbers.
Habitat & Behavior
Crickets live outdoors in warm weather but seek indoor shelter when temperatures drop in fall. They prefer warm, moist areas and hide near kitchens, fireplaces, behind appliances, in basements, and crawl spaces. Outdoors, they inhabit mulch, leaf litter, tall grass, and areas around building foundations. They're attracted to lights at night and enter through open doors, windows, and cracks.
Signs of Infestation
- Loud, persistent chirping sounds at night, especially in basements
- Live crickets jumping when you turn on lights in dark areas
- Damage to fabrics, particularly items soiled with food or perspiration
- Dead crickets near doors, windowsills, or in light fixtures
- Increased cricket activity during fall months
Health & Property Risks
Crickets are primarily nuisance pests whose constant chirping can disrupt sleep and peace in your home. They can damage fabrics including wool, cotton, silk, and synthetic materials, especially items stained with food or perspiration. While they don't bite or spread disease, large cricket populations indicate entry points that could allow more serious pests inside. Their presence can also attract predators like spiders and centipedes.
Prevention Tips
- Reduce outdoor lighting or use yellow bug lights that are less attractive
- Seal cracks around doors, windows, and foundation with caulk or weather stripping
- Keep grass cut short and reduce mulch depth near foundations
- Remove leaf litter, woodpiles, and debris from around your home
- Install tight-fitting screens on windows, doors, and vents
- Eliminate moisture sources by fixing leaks and improving ventilation
Professional Treatment Approach
Greenix's cricket control program emphasizes exterior prevention with perimeter treatments around foundations, entry points, and potential harborage areas. We apply residual insecticides to create a protective barrier that stops crickets before they enter your home. Interior treatments focus on basements, crawl spaces, and areas where crickets are active. We provide guidance on reducing attractants like outdoor lighting and entry point sealing.

German Cockroaches
German cockroaches are small, light brown to tan insects measuring 1/2 to 5/8 inch long with two distinctive dark parallel stripes behind their heads. Despite having wings, they rarely fly and prefer to run. These prolific breeders are the most common cockroach species found in homes, restaurants, and food service establishments.
Silverfish
Silverfish are wingless, teardrop-shaped insects measuring 1/2 to 3/4 inch long with silvery-gray scales covering their bodies. They have three long tail-like appendages at the rear and two long antennae at the front. These primitive insects move in a distinctive fish-like wiggling motion and can live 2-8 years.
Earwigs
Earwigs are reddish-brown insects measuring 5/8 to 3/4 inch long with distinctive pincers (forceps) at the rear of their abdomen. Males have curved forceps while females have straight ones. Despite having wings folded under short wing covers, they rarely fly. The old wives' tale that they crawl into human ears is unfounded.
