Camel crickets are one of those insects that are just so icky to me! The crickets are so-named because of their slightly hump-backed appearance. Adults are 1"-1.5" long. Their long legs give them a creepy, spider-like appearance. Interestingly, camel crickets do not "sing" or "chirp" like most other crickets do. And unlike other crickets, camel crickets do not have wings as adults.

Camel crickets are usually associated with cool, damp, dark places. Outdoors, they can be found under stones and logs, in stacks of firewood or other debris, or in leaf litter. Areas that are overgrown with thick vegetation, such as ivy and other ground cover provide excellent hiding places. Camel crickets often inhabit moist, humid areas in and around our home, such as crawlspaces, basements, garages, and other indoor areas where moisture may be a problem. A telltale sign of a heavy infestation is the presence of dark fecal smears on surfaces (such as on the floor joist in the picture below).

Like other crickets, camel crickets will invade buildings in the fall seeking suitable places to pass the winter. In these cases, they often remain in basements or crawlspaces and seldom damage items in the home. Although they are mostly a nuisance pest, camel crickets can damage stored items, such as garments and linens packed in boxes in a garage or basement, if the problem goes unchecked for some time and the crickets cannot find suitable food.

Controlling camel crickets.
Because moisture is such an important requirement for camel cricket survival, reducing the number of moist habitats is essential for good, long-term control. Doing what you can to prevent crickets from entering the structure is also important. Following a few simple steps can accomplish both strategies and will go a long way in effectively controlling these crickets.

• Keep weeds and tall grass next to the building mowed.
• If possible, keep mulch, thick ground covers, and shrubs away from the foundation wall.
• Store lumber, fire wood, and other wood piles away from the foundation.
• Make sure windows have screens that fit properly and are not torn.
• Install weather-stripping around all doors and windows.
• Seal small openings on the outside of the home with caulk.
• Install screen on crawlspace and dryer vents.
• Make sure crawlspaces and basements are properly ventilated to reduce moisture.
• Any boxes stored in basements or garages should be stacked away from the wall. If possible, stack the boxes on pallets.
• Camel crickets that make their way inside can be vacuumed up, squashed (yuck), or placed outdoors.
• If you have a cat or dog, they may take care of the camel cricket for you; mine always do!
