The European earwig is the most common to Illinois and is a dark, reddish-brown insect. You can easily identify an earwig by the pincer-like protrusions at the end of their abdomen. These protrusions are called forceps.
Color – Dark, reddish-brown
Length – 5/8 to an 1” long.
Diet – Their diet consists of fruit, mold, leaves, flowers as well as other insects.
Habitat – Since earwig likes dark areas, they are most active at night. They also prefer their habitat to be an area with moisture. If you turn over an old log, you are bound find an earwig under it. If they have made it into your home it will usually be from some crack that is allowing them in from the outside.
Impact – They are not poisonous and don’t spread disease. While they don’t necessarily bite, they can pinch the skin with their forceps. In greater numbers, they can impact your garden, as they will feed on various fruits, leaves or flowers.
