The answer to 'why is my cockroach odor' is that cockroaches can produce a strong, unpleasant odor when they are present in large numbers. This odor is caused by the release of pheromones and other chemicals from the cockroaches' bodies. The odor is often described as musty, oily, or even sweet, and it can linger in areas where cockroaches have been present.
The odor is a common symptom of a cockroach infestation, and it can be a sign that you need to take action to eliminate the pests. Cockroaches can also spread diseases and contaminate food, so it's important to address the problem as soon as possible.
