Crickets
Acheta domesticus / Gryllus assimilis
Identification, behavior, health risks, prevention, and professional treatment options for Central Florida residents.
Overview
Crickets are familiar insects across Central Florida, and while they are benign outdoors, they become a meaningful pest when they invade structures or accumulate in large numbers around entry points. The house cricket (Acheta domesticus) and the Florida field cricket (Gryllus assimilis) are the most common species affecting homes and businesses. In addition to the noise nuisance — male crickets chirp continuously to attract mates and do not cease once inside — crickets can cause fabric and paper damage in large numbers and attract secondary predators such as spiders and centipedes into the home. Cricket populations in Central Florida peak in summer and early fall. Large numbers are commonly drawn to commercial and residential structures at night by outdoor lighting. Once a few crickets enter, the chirping of males can attract additional crickets from outside, and populations in crawl spaces, garages, and basements can build quickly.
Appearance
House crickets are 3/4 to 7/8 inch long, yellowish-brown with three dark bands on the head, and have long thread-like antennae that may exceed their body length. Field crickets are slightly larger, darker brown to black, and more robust in build. Both species have powerful hind legs adapted for jumping and, in males, wings used to produce the chirping sound by rubbing them together (stridulation). Females are identified by the long, sword-like ovipositor projecting from the rear of the abdomen.
Behavior & Habits
Crickets are primarily nocturnal and omnivorous — they feed on plant material, organic debris, other insects, and fabric (particularly natural fibers soiled with food or perspiration). Indoors, they congregate in warm, moist areas: around water heaters, under sinks, in basements and crawl spaces. Male crickets chirp most actively when temperatures are above 55°F. Outdoor lighting is the primary cricket attractant — structures with intense exterior lighting attract far larger cricket populations to the building perimeter each evening.
Prevention
Reduce exterior lighting intensity or convert to yellow sodium vapor or LED lighting that is less attractive to flying insects. Seal door sweeps, foundation gaps, and utility penetrations. Keep garage doors closed at night during peak cricket season (late summer and fall). Remove dense ground cover, leaf litter, and debris adjacent to the foundation where crickets shelter during the day.
Professional Treatment
Cricket management uses residual insecticide applied to the exterior perimeter, foundation band, and entry points, supplemented by granular bait products. Interior treatment targets harborage areas in garages, crawl spaces, and utility rooms. Reducing exterior lighting is often the most productive single action for structures with very high cricket pressure. GreenCore Environmental addresses cricket invasions as part of standard perimeter pest control. Call (866) 816-BUGS.
Why Professional Treatment Matters
Field crickets and house crickets invade Florida structures during fall when cooling temperatures drive them to seek warm shelter. A cricket infestation inside a structure is not just a noise issue — large cricket populations damage natural fiber textiles, paper products, and leather goods with their feeding. Consumer exterior sprays provide temporary knockdown but do not address the large outdoor populations that are the source of interior invasions. Florida's warm winters mean cricket populations persist year-round at lower levels, with dramatic invasion events in late summer and fall. Without a maintained perimeter treatment, crickets will exploit every gap around doors, windows, and utility penetrations to enter structures in large numbers.
GreenCore Covers Crickets
GreenCore treats cricket pressure with granular perimeter bait applied around the structure's exterior, which crickets consume as they move through the landscaping toward the building. Exterior entry points — door sweeps, window weep holes, foundation vents, and utility penetrations — are treated with residual liquid. Interior treatment addresses confirmed cricket activity in garages, basements, and utility areas. Cricket service is included in GreenCore's General Pest Control program, and recurring quarterly visits maintain the granular bait barrier through the outdoor cricket season.
