Unpleasant odors – One surefire sign of a roach infestation is the presence of a foul odor. Common American cockroaches emit a strong, unpleasant smell, which is extremely evident inside an infested building and on items roaches may have crawled on. These odors are so distinct that a skilled Fort Wayne exterminator may be able to tell if a building is infested by merely sniffing the air. A single roach doesn’t emit a strong, perceptible odor on its own; but when these pests swarm, they give off that characteristically foul oily or musky smell.
Egg casings – All cockroach species produce casings, called oothecae, which contain multiple eggs–about 10 or 20 inside each casing. They are brown in color, and range from 5 mm to 10 mm in length. If you see these small, brownish, elongated egg casings in your home, you might have an infestation under your nose.
