The answer to 'why is my pest odor' is that a persistent pest odor is often caused by the presence of dead or decaying pests in your home. This can happen when pests like mice, rats, or insects die in hard-to-reach areas like walls, attics, or crawl spaces. As the bodies decompose, they release strong, unpleasant odors that can permeate your living space.
Other common causes of pest odors include the scent of live pests, such as the musky smell of rodents or the pungent odor of insects like cockroaches. Pest urine and droppings can also contribute to lingering odors. Addressing the root cause of the pest problem is key to eliminating the odor.
