Why Do Cockroaches Release a Smell?

A common question that may occur to you is, “Why do cockroaches release a scent?” This is an important question because cockroaches do expel a smell when they die. They release nitrogenous wastes in the form of semisolid poop and urine, both of which have a pungent smell. The smell intensifies as the poop and urine mix together.

The smell that cockroaches release is a result of chemical signals they give off. A single cockroach has a very faint smell, but a swarm of them releases a distinctive smell. This odor is called pheromone, and is detectable by humans.

The smell from cockroaches can be a sign of an infestation. If you have found cockroaches, their body parts, droppings, and molts, the stench will be present for a long time. During this time, you may need to replace infested items, or even disinfect your home. The smell may also attract more cockroaches. It’s a good idea to seek out the services of pest management professionals who can eradicate your cockroach infestation and sanitize your home to avoid re-infestation.

When it comes to the smell of cockroaches, the most common source is the roach nest. This nest is usually located in cracks or crevices, where roaches can hide out. Their habitat is dark and moist. You can recognize a cockroach nest by a pile of feces, egg cases, and shed skins.
