Something is lurking in your basement: big and humpbacked, with legs long enough to make most people mistake it for a spider. When the lights come on, it jumps right at you. If that sounds familiar, you're dealing with cave crickets, and you're far from alone.
Cave crickets are one of the most common basement pests in Bergen, Passaic, Morris, and Sussex County homes. They're especially active during New Jersey's hot, humid summers, when they move indoors to find cooler, damper conditions. Here's what they are, why they're in your house, and what actually works to get rid of them.
What Are Cave Crickets?
Cave crickets (Ceuthophilus spp.) go by several names around here: camel crickets, spider crickets, or sprickets. Unlike the crickets you hear chirping outside at night, cave crickets don't make noise. They have no wings, no song, and no interest in being seen. They prefer dark, damp corners and come out mostly at night.
What they do have is an unmistakable look: a strongly humped back, extremely long antennae, and powerful back legs built for jumping. When startled, they leap toward whatever is moving (usually you) as a defense mechanism. The jump is a defensive reflex. Cave crickets leap toward movement when startled, which is usually enough to send most homeowners out of the room fast.
Why Are Cave Crickets in My House?
Cave crickets follow moisture. During New Jersey's summer months, when outdoor temps climb and humidity stays high, these insects move inside to find the cool, dark, damp conditions they need to survive. Basements, crawl spaces (the low area between the ground and the floor of your home), utility rooms, and laundry areas are prime spots.
Common entry points and conditions that attract them include:
- Cracks or gaps in the foundation (the concrete base of your home) or around window wells (the curved recesses outside basement windows)
- Unscreened basement vents or dryer exhaust openings
- High indoor humidity, typically above 60%
- Dense mulch or vegetation piled against the foundation
- Firewood stacked directly against the house
Once inside, cave crickets aren't picky eaters. They feed on plant matter, fabric, cardboard, other insects, basically whatever they find. A large population can damage clothing, stored items, or anything else left in your basement over a full summer.
Are Cave Crickets Dangerous?
No. Cave crickets don't bite people, don't sting, and don't carry disease. They are a nuisance pest, not a health hazard. The issue is that they multiply quickly. What starts as a handful of crickets in early summer can become a much larger population by August if the conditions in your basement stay favorable.
What Time of Year Are Cave Crickets Most Active in NJ?
Cave crickets are active year-round but show up indoors most during summer and early fall. As outdoor temperatures climb and conditions get drier, they push inside to find humidity. Homeowners in Bergen and Passaic County tend to notice them most from June through September, with populations peaking when summer heat is at its worst.
In fall, some cave crickets lay eggs in protected indoor spots before dying off. That means if you ignore a summer problem, you may be dealing with a new batch the following spring.
How to Get Rid of Cave Crickets in Your NJ Home
Steps You Can Take on Your Own
Getting rid of cave crickets takes two things: fixing the conditions that attract them and treating the ones already inside.
- Run a dehumidifier in your basement and keep humidity below 50%
- Fix any leaks, dripping pipes, or water intrusion issues
- Move firewood storage away from the house
- Pull mulch and dense plantings back from the foundation
- Seal cracks in the foundation, around window frames, and along door sweeps
Sticky traps along basement walls can catch individual crickets, but they won't eliminate an established group. If you're seeing crickets regularly or in more than one room, there's a population living and breeding inside that traps alone can't reach.
