Kitchen invaders are unwelcome guests that can be found in many kitchens. The most common kitchen invaders are roaches, ants, and red ants. Roaches are five-letter insects that are usually brown or black in color and have long antennae. Ants are three-letter insects that come in a variety of colors and sizes and are often seen marching in lines. Red ants are six-letter insects that are usually red or orange in color and have a painful bite. All of these kitchen invaders can be a nuisance and should be removed from the kitchen as soon as possible.
