Camel Crickets: The Basement Insect That Jumps At You

The cricket in an Ohio basement is usually a camel cricket: humpbacked, wingless, completely silent, and startling because it jumps toward you when the light comes on. The cricket you can hear chirping is a different insect that walked in from the lawn. One is telling you the house is damp. The other is telling you a door is open.

Both get noticed in the same few weeks of October around North Canton, and they usually get treated as one problem. They are not. The fixes point in opposite directions, and only one of them is worth losing sleep over.

Which Cricket Is In Your Basement?

Look at the shape and listen for nothing. Clemson Cooperative Extension describes the camel cricket as humpbacked, with the head bent downward between the front legs, antennae much longer than the body, and large hind legs that make it a very strong jumper. It has no wings, so it cannot fly and it cannot chirp. Clemson adds the part that matters for a homeowner: their preference for dark, moist places almost always restricts them to damp basements and crawl spaces.

There is a good chance the one in your laundry room is not even a native insect. A North Carolina State University citizen science project, published in the journal PeerJ, asked households across the eastern United States to report and submit the camel crickets they found. More than 90 percent of respondents reported the greenhouse camel cricket, Diestrammena asynamora, an Asian species that became established here in the 1800s and was long assumed to stay in greenhouses. It did not stay in greenhouses. It moved into basements.

The One You Can Hear Is Something Else Entirely

Chirping means wings. Clemson Cooperative Extension explains that adult male crickets produce sound by rubbing their wings together, either to attract females or to sound an alarm when they are disturbed, and that house and field crickets are both more active at night and may be drawn to light. So the sound behind the dryer at midnight is a winged cricket that came in near a lit door, not the silent thing in the crawl space.

The caller in an Ohio yard in September and October is usually the fall field cricket, Gryllus pennsylvanicus, which Ohio State University notes lays its eggs in soil. That detail is the whole answer to the panic question. A field cricket indoors has nowhere to lay eggs and no colony behind it. It is a stray with a few weeks to live. A camel cricket in a wet crawl space is in habitat it likes, and it has company.

Why They All Turn Up In The Same Three Weeks

Autumn runs on one signal and every insect reads it. Ohio State University Extension, in its BYGL fall invader coverage, describes the pattern: these insects feed heavily in late summer to put on fat, then look for sheltered places as cooler temperatures slow their metabolism down. Crickets are on the same clock as the boxelder bugs and lady beetles collecting on the south wall of the house.

Where they settle is decided by water, not warmth. A camel cricket walking the foundation of a Stark County house passes a dozen dry places and stops at the one that is damp: the crawl space under the back addition, the block wall behind the stacked storage totes, the window well packed with wet leaves. Older Canton and Akron housing stock gives them plenty of those spaces, and a wet October week keeps every one of them hospitable.

What They Actually Do Once They Are In

Less than their looks suggest, up to a point. University of Maryland Extension says camel crickets do not bite. North Carolina State Extension treats them as mostly a nuisance pest, but notes that in large numbers indoors they can damage fine fabrics and houseplants, and that garments and linens packed into boxes in a basement or garage can be chewed if the problem goes unchecked for a long time.

The jumping is a reflex, not an attack. Clemson Cooperative Extension points to those large hind legs and notes that camel crickets jump when they are disturbed. With no wings and no steering, the jump goes wherever the insect was pointed, which on a basement stairway is frequently at the person holding the light. That reflex is most of the reason a harmless insect has the reputation it does.

What Actually Keeps Crickets Out

Work the conditions before you work the insect. Nearly all of this is one weekend of work with a caulk gun and a dehumidifier, and it pays off against far more than crickets.

• Dry the space first. Clemson Cooperative Extension calls reducing moist habitat essential for good long term control and recommends properly ventilating crawl spaces and basements. EPA mold and moisture guidance puts the target for indoor relative humidity below 60 percent, and ideally between 30 and 50.
• Close the ground level openings. Clemson lists tightly fitted screens on doors and windows, weather stripping along the bottom of windows and of house and garage doors, and caulk or screening over small openings, including crawl space vents and dryer vents.
• Clear the foundation line. Leaves in window wells, boards on the ground, and totes stacked against a block wall are harborage sitting right next to the entry point you just sealed.
• Change the porch bulb. For the chirping kind, Clemson suggests reducing lighting around doors and windows, or switching to yellow or sodium vapor lights, which are less attractive to crickets.
• Deal with what is already inside. Clemson recommends glue or sticky traps near doorways, and a vacuum where the numbers are small. Both work better once the moisture is gone.
• Get storage off the concrete. Cardboard holds damp and the contents are chewable. Sealed plastic bins on a shelf solve both at once.

When Is It Worth Calling Somebody?

When the harborage is the building itself. A crawl space with bare soil, a block wall that sweats every humid week, an attached garage with daylight under the door: those keep producing crickets no matter how many you vacuum up, because the conditions never change. Clemson is blunt that indoor chemical treatment is worth considering only when a population is large or when it threatens something valuable, which is the right order of operations. Dry it out, seal it up, then treat the outside so the next wave stops at the foundation.

That outside perimeter is the part most people do not want to repeat four times a year. Our State Shield Essential plan is built around it: four visits a year, timed to break egg cycles rather than to chase whatever crossed the floor last night, covering ants, spiders, millipedes, centipedes, cockroaches, mice, rats, bees, wasps and seasonal invaders. If pests come back between treatments, so do we, at no cost.

Still not sure what jumped at you? Our occasional invaders library covers the rest of the damp basement crowd. We have been working Northeast Ohio since 1933, out of North Canton and Hartville, across Stark, Summit, Portage, Wayne and Tuscarawas counties.
