About Camel Crickets

Family: Rhaphidophoridae

Camel crickets, also called cave or spider crickets, are humpbacked insects typically found in damp, dark environments. These pests are frequently seen in basements, crawl spaces, and other places with high humidity. Unlike other crickets, camel crickets do not chirp, but their sudden jumping behavior and tendency to appear in groups can make them especially unsettling indoors.

Behavior and Risks

Camel crickets are typically found in groups, thrive in dark, damp environments, and are most active at night. Favoring humid conditions, they frequently inhabit basements, crawl spaces, and other moisture-rich locations.

Homeowners may observe camel crickets jumping suddenly when startled, sometimes toward movement, making encounters more surprising.

Although camel crickets do not damage structures or pose health risks, their numbers can increase rapidly under favorable conditions. Indoor infestations often signal excessive moisture, poor ventilation, or cluttered spaces that provide shelter. Reducing humidity, improving ventilation, and removing hiding spots are essential steps to prevent camel cricket problems indoors.
