American cockroaches are disgusting home invaders with a reddish brown tint. They scurry around on their 6 legs looking for food. Growing from 1.25 inches to 1.7 inches in length, these pests can infest a house quickly due to their fast reproductive habits.
Ants can be black, brown, red, yellow or some variation of any of these colors. In the USA, they range in size from a little less than a millimeter to nearly 2 inches long. They have 3 segments to their body and six legs. Their antennae stick up from their heads and are bent rather than simply curved. An ant's abdomen has a teardrop shape to it.
