Cave Crickets in Your Basement: Why Rockland County Homes Get Them
Those humpbacked, long-legged insects jumping around your basement aren't dangerous — but a cave cricket infestation in Rockland County can grow large quickly. Here's what they are and how to get rid of them.
The Strange-Looking Insect in Your Rockland County Basement
If you've gone down to your basement in Nanuet, New City, Pearl River, or Suffern and encountered an insect that looks like a spider crossed with a shrimp — humpbacked, tan to brown, with absurdly long legs, and absolutely no hesitation about jumping directly at your face — you've met the cave cricket.
Also called camel crickets, spider crickets, or sprickets, cave crickets (Ceuthophilus species) are one of the most unsettling-looking insects that regularly inhabit Rockland County homes. They're also one of the most misunderstood: many homeowners spend money on the wrong treatments because they mistake cave crickets for something more dangerous than they actually are.
This guide covers what cave crickets actually are, why Rockland County homes get them, and exactly how to deal with them.
What Cave Crickets Are (And Aren't)
Cave crickets are not true crickets. They don't chirp. They're not the insect making noise outside your window at night. They're not venomous spiders. They're a separate family of cricket (Rhaphidophoridae) that has adapted to living in dark, damp, cave-like environments — which in a suburban Rockland County home means your basement, crawl space, or utility room.
Physical characteristics:
What they do when disturbed: They jump. Rapidly, erratically, and often toward whatever startled them rather than away from it. This is a defense response — the unpredictable jump trajectory makes them harder to catch. It is extremely startling and explains why so many Rockland County homeowners call us in a panic.
What they don't do: They don't bite (they can't — their mouthparts aren't designed for it), they don't sting, they don't transmit disease, and they don't damage your home's structure.
What they CAN do in large numbers: chew on fabric, paper, and light organic materials. A significant cave cricket population in a basement with stored clothing, cardboard boxes, or old textiles can cause real damage over time.
Why Rockland County Homes Are Particularly Attractive to Cave Crickets
Rockland County sits in a geographic sweet spot for cave cricket habitat: the Hudson Valley's transition from suburban to semi-rural landscapes, with significant woodland edges, hillside properties, and older housing stock with basements that tend toward the damp.
The moisture connection. Cave crickets require humidity. They're physiologically unable to survive in dry environments. Rockland County's basements — many in homes built in the 1950s-1980s in communities like New City, Pearl River, and Nanuet — tend to have higher humidity levels than modern construction, especially in summer when outdoor humidity rises and basement temperatures remain cooler (causing condensation).
Proximity to wooded areas. Cave crickets' natural habitat is under rocks, logs, and leaf debris in shaded woodland areas. Rockland County's abundance of wooded lots, state parks, and hillside properties means there are large outdoor cave cricket populations adjacent to residential structures. Harriman State Park, Rockland Lake State Park, and the wooded corridors throughout the county provide extensive natural habitat that borders residential areas in Suffern, Congers, and Blauvelt.
Outdoor harborage that connects to foundations. Wood piles against the foundation, heavy mulch beds, dense ground cover plantings, and firewood stored under decks all provide outdoor staging areas for cave crickets before they move inside.
Entry points. Cave crickets enter through gaps around basement windows, cracks in foundation walls, gaps where utility lines penetrate the foundation, and through door thresholds and window wells. Older Rockland County homes have more of these entry opportunities than newer construction.
Signs You Have a Cave Cricket Problem
• Seeing them in your basement or crawl space. This is the obvious one. One or two cave crickets is common in Rockland County basements. More than a handful on a regular basis suggests an infestation.
• Fecal droppings. Small dark specks on surfaces in damp basement areas.
• Damage to stored items. Chewed fabric, paper, or cardboard stored in damp basement areas — though this level of damage requires a significant population.
• Egg masses in damp areas. If you're dealing with a significant infestation, you may find clusters of small white oval eggs in moist soil, in crawl space areas, or in damp insulation.
How to Get Rid of Cave Crickets
Effective cave cricket control in Rockland County requires addressing the moisture problem, reducing outdoor harborage, and treating existing indoor populations. Doing only one of these without the others leads to recurring problems.
Step 1: Reduce Basement Humidity
A dehumidifier running in your basement during spring through fall (when outdoor humidity is highest) is the single most impactful long-term cave cricket deterrent. Cave crickets cannot thrive in a dry basement. Target relative humidity below 50%.

Step 2: Remove Outdoor Harborage
Step 3: Seal Entry Points
Step 4: Use Sticky Traps
Glue traps (also called sticky traps) placed along basement walls are highly effective at catching cave crickets and monitoring population levels. Place them along walls, in corners, and under shelving. Check them every few days. They don't kill cave crickets — they capture them — but they're very useful for assessing how significant your population is.
Step 5: Professional Treatment for Established Infestations
If you're dealing with dozens of cave crickets or can't get the moisture and entry point issues under control, professional treatment is the most efficient path. Professional pest control for cave crickets includes:
What Cave Crickets Are NOT Telling You
Finding cave crickets in your Rockland County basement is not a sign of a dirty home. It's a sign of accessible moisture and entry points — both extremely common in the older housing stock of New City, Pearl River, Suffern, and Nanuet.
It's also not an indicator of other, more concerning pest problems. Cave crickets don't indicate the presence of termites, carpenter ants, or rodents. They're their own issue requiring their own solution.
FAQ: Cave Crickets in Rockland County
Q: Can cave crickets hurt me or my pets?
No. Cave crickets don't bite, sting, or transmit disease. The jump response is alarming but harmless. Your pets may actually be more disturbed by the jumping than you are — or they may find them entertaining to chase.
Q: Will they come upstairs from the basement?
Cave crickets strongly prefer dark, damp environments. They don't typically venture into bright living spaces unless their basement habitat is disturbed or overcrowded. Keeping the basement door sealed reduces this possibility.
Q: I've tried sprays and they keep coming back — why?
Because sprays address the insects already present without addressing why they're coming in (moisture, entry points, outdoor harborage). This is the most common cave cricket treatment failure pattern.
Q: Are they related to the crickets that chirp outside?
Cave crickets are in the same order as true crickets (Orthoptera) but are not true crickets. They don't have sound-producing organs and don't chirp. The noise you hear outside at night is from field crickets, not cave crickets.
Q: How quickly can a cave cricket population grow?
Female cave crickets lay eggs in moist soil or debris. Without population control, a small infestation can become a significant one over the course of a spring and summer season in a humid Rockland County basement.
