Greenhouse camel crickets are small, 11 to 15 mm long, with very long antennae and a gray-to-brown body marked with dark spots and rings on the legs. They live in warm, moist places such as greenhouses, cellars, and caves, and are active at night, hiding during the day. They eat both small insects and plant material, and can damage seedlings, fruits and other greenhouse crops.

Is it a pest in the house?

They are crepuscular and nocturnal, and can become a nuisance in greenhouses when they occur in large numbers.

How to get rid of it

Targeted control measures have reduced their numbers in botanical gardens. In the U.S., people have been asked to survey homes for camel crickets and send specimens to a university for research.

How this page works

This is one bug's fact sheet. The colored box at the top says whether it is dangerous. Sections below cover how to recognize it, whether it is a pest, and how to deal with it. The US map shows which states have records; tap a state to see other bugs there.

Every fact on Bug FAQ comes from a named source (university extension sites, government agencies, GBIF, iNaturalist, Wikipedia). The source is linked next to each section. If we have no source for something, we leave it out.
