How to Get Rid of Cave Crickets (Camel Crickets) in NJ Basements
To permanently eliminate cave crickets (camel crickets), reduce basement relative humidity below 50% using a commercial dehumidifier, deploy non-toxic sticky glue traps along foundation sill plates and sump pumps, and apply food-grade diatomaceous earth into dark masonry voids.
Basement Desiccation Threshold & Dehumidifier Capacity Sizing
Target < 48% RH to induce rapid nymph desiccation within 72 hours.
The 4-Step Non-Toxic Cave Cricket Elimination Protocol
The greenhouse camel cricket (Diestrammena asynamora) is an invasive rhaphidophorid cricket native to Asia that thrives in humid subterranean conditions across New Jersey. Unlike field crickets, camel crickets cannot chirp and do not produce mating calls; instead, they congregate in colonies wherever relative humidity exceeds 65%.
Mechanical Humidity Deprivation
Camel crickets lack the protective waxy epicuticle found on desert insects. Lowering basement humidity to 45%–50% desiccates nymphs and eliminates damp mold spores that serve as their primary food source.
Perimeter Sticky Monitor Trapping
Place non-toxic scented glue boards flat along foundation floor plates every 12 feet. Traps intercept breeding females migrating from crawlspaces toward warmer laundry and furnace areas.
Diatomaceous Earth Dust Barrier
Apply amorphous silica diatomaceous earth into baseboard voids. The microscopic razor-sharp diatoms pierce cricket joint membranes, resulting in physical desiccation within 48 hours without toxic pesticides.
Exterior Perimeter Exclusion
Remove woodpiles, rotting leaf mulch, and dense groundcover within 3 feet of your home's foundation. Seal exterior siding weep screeds and window well gaps with stainless steel mesh and silicone.

Why Total-Release Foggers ("Bug Bombs") Fail Against Camel Crickets
The Aerosol Fogger Trap
A widespread homeowner error across New Jersey is discharging over-the-counter pyrethroid foggers in basements. Foggers emit aerosolized chemical droplets that rise toward ceiling joists and settle harmlessly on flat horizontal surfaces. Because camel crickets harbor deep inside dark vertical foundation expansion joints, sump pump recesses, and insulation pockets, aerosol foggers rarely contact nesting colonies.
The Erratic Scatter Reflex
Airborne pyrethroids excite the sensory antennae of camel crickets before reaching a lethal dose, triggering mass erratic leaping that scatters disoriented crickets into upper living areas and kitchen cabinets. Structural desiccation through sustained humidity control remains the only permanent scientific remedy endorsed by university entomologists.
Frequently Asked Questions: Cave Crickets & Basement Pest Control
01Why do cave crickets jump toward you when frightened?
Cave crickets have very poor vision and navigate primarily using long tactile antennae. When startled by vibrations or light changes, their defensive evolutionary reflex is to leap erratically in high vertical arcs toward the perceived threat to startle potential predators.
02Do camel crickets bite humans or carry diseases?
No. Cave crickets lack venom glands and do not possess mouthparts capable of puncturing human skin. They are not known to transmit vector-borne pathogens, though large infestations can damage indoor fabrics, cardboard boxes, and stored clothing through chewing.
03What relative humidity level stops cave cricket breeding?
Cave crickets lack protective wax epicuticles on their exoskeletons, making them highly susceptible to desiccation. Maintaining indoor basement relative humidity strictly below 50% dries out eggs, prevents fungal mold growth (their primary food source), and forces adults to perish or relocate.
04Where should sticky glue traps be placed in a basement?
Place sticky traps flat against walls in dark, undisturbed areas: around perimeter foundation walls, behind water heaters, adjacent to sump pump pits, underneath basement stairwells, and directly below floor joist sill plates where pipes penetrate masonry.
