Acockroach infestation can cause trouble in a number of ways, but one of the grossest is the smell associated with them. A heavy roach infestation can leave your apartment, house, or place of business with a stench that can be nearly unbearable. So, what causes roach smell, and how can you get rid of roach smell?
People often use words like musty, oily, sooty, or mildewy to describe roach smell. The Oriental roach is said to produce one of the worst smells, but German and American roaches can also give off a foul stench.
There are three main reasons why roaches smell. The first is their normal secretions, known as pheromones. Pheromones are a form of communication and can be used to attract mates and gather other roaches to a good nesting spot. The second cause of roach smell is from feces. Roaches poop wherever they live or travel. The excrement contains some of the previously mentioned pheromones, but it can also start to grow mold, which will add to the stench. Cockroaches most often live in dark, moist environments that are optimal for mold growth. Lastly, when cockroaches die, they give off a “death stench.” Decaying bodies and shed skins from molting will release oleic acid, which also has a powerful smell.
