Camel crickets get their name because
of their slightly humpbacked appearance. Their long legs give
them a spider-like appearance. Unlike other crickets, they do not have wings as adults. There are actually several species called camel crickets, but most of them are unimportant as pests. One species, Tachycines asynamorous or "greenhouse stone cricket" frequently
becomes a nuisance indoors. As its name suggests, this species is frequently found in greenhouses. Unlike
most cricket species that we see, camel crickets do not "chirp". If you are hearing
chirping sounds indoors, then you likely have field crickets, which can be controlled
the same manner, as outlined below. Outdoors, camel crickets are typically
found in moist areas including under stones and logs, or in stacks of firewood.
that are overgrown with vegetation such as ivy and other ground covers provide
excellent hiding places (harborages). Camel crickets pass the winter
nymphs (immatures) or adults. The nymphs
looks almost identical to the adult, except that they are smaller.
In early spring, adult females begin to lay
eggs in the soil. A few weeks later, the nymphs hatch from these eggs.
Problems with Camel Crickets
Non-chemical control methods
Outdoors: Any chemical control should focus first on outdoor barrier
treatments. Sprays applied to foundation walls, around vents crawlspace
accesses, basement doors and windows, and insecticidal baits applied along
the perimeter can be quite effective unless there are heavy rains. In crawlspaces,
insecticidal baits placed in corners or along the sill plate will be most
effective. Spraying in a confined area, such as a crawlspace, requires
and the proper application and safety equipment. Granular baits are a better
choice for use in a crawlspace, but these products are not readily available
to the general pubilc. You can or else contact a licensed pest control company
for assistance. Consult your county Cooperative
Extension Service Center or the
NC Agricultural Chemicals Manual
for a list of appropriate pesticides.
