The answer to 'why is my ant odor' is that ants can produce a distinct odor, often described as a musty or rotten smell, when they are disturbed or threatened. This odor is caused by the release of pheromones and other chemicals from the ants' bodies as a defense mechanism.
Common causes of ant odor include an ant infestation in your home, such as in the walls, floors, or kitchen. The more ants present, the stronger the odor will be. Symptoms may include a noticeable smell, as well as the presence of ants themselves. To address the problem, you can try DIY solutions like using natural ant repellents or baits, but for a severe infestation, it's best to call a professional pest control technician who can properly identify the ant species and apply targeted treatments.
