Instantly recognizable by their song, crickets are an occasional home invader and common denizen of the landscape. These small, jumping insects are members of several different species, but the most commonly encountered are field crickets (Gryllus species) and house crickets (Acheta domesticus). House crickets have been living side by side with humans for generations, earning themselves the nickname "Cricket on the Hearth."
Commonly encountered in yards, basements and barns, crickets are jumping insects typically measuring from about 9/16 to just over an inch long. These insects vary in color from brown to shiny black, with leathery wings and long antennae. Eggs hatch in late spring or early summer – those nymphs grow into adults in about 45 days. The males of these newly adult crickets will begin singing to attract females at this time and continue throughout the summer.
Several kinds of crickets are found in Arizona. Although they pose no immediate health risks (they do not bite or carry disease) they have been known to eat through everything from wallpaper glue to wool to silk.
