What do ground beetles look like?

Ground beetles are mostly black or dark brown and may have an iridescent coloration. They are often mistaken for cockroaches because of their coloring, as well as their seed-like body shape and spines on the legs. One key difference between a ground beetle and a cockroach is the lack of cerci. At the end of a cockroach's abdomen are two small appendages called cerci that stick out at a 45-degree angle. Adult beetles don't have these appendages.

Grubs feed on the roots of turfgrass and can cause grass blades to die. The sign of a grub problem is patches of yellow or gray grass on your lawn.

Can ground beetles infest your house?

No. Ground beetles are unable to complete their life cycle indoors. They may get inside when opportunities present themselves, such as an open door or window or a gap around a pipe.
