Mole crickets are a type of cricket that get their name from their habit of burrowing into the earth like moles. They live on lawns in the Southeastern United States and throughout Canada and damage grass by burrowing tunnels in the soil and eating the grass. This results in brown patches in the grass. They also attract predators like raccoons that damage the grass as well.
Mole crickets are roughly 3-5 centimeters long with wings and large front legs that they use to dig in soil. Most though not all species are able to fly for short distances. Mole crickets lay their eggs in the tunnels they make underneath the soil. They are nocturnal and are omnivores meaning that they eat worms and larvae as well as grass. In cold weather, mole crickets hibernate and they are generally at their most destructive from August through October.
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.
