What Are Field Crickets?
Field crickets (Gryllus spp.) are common outdoor insects in North Carolina that occasionally invade homes, especially in late summer and fall. Adults are dark brown to black, about 15–25 mm long, with long antennae and prominent hind legs adapted for jumping.
Habitat & Behavior
Male field crickets produce the familiar chirping song by rubbing their forewings together to attract mates. While charming outdoors, this chirping becomes a significant nuisance when crickets enter homes—especially at night. A single cricket inside a bedroom wall can disrupt sleep for days.
Field crickets feed on plants, other insects, and organic materials. Inside homes, they may damage fabrics, paper, and wallpaper. They are strongly attracted to lights and will congregate around illuminated buildings, eventually finding their way indoors through gaps under doors and around windows.
Prevention & Control
To reduce cricket invasions, switch outdoor lighting to yellow “bug lights” or sodium vapor lamps that are less attractive to insects. Seal gaps under doors with weatherstripping and caulk cracks in the foundation. Remove tall grass, weeds, and debris from around your home’s perimeter. Sticky traps placed along walls can capture crickets that do get inside.
