If given even the smallest chance, pests can and will enter your air ducts. Contamination and structural damage caused by pests in a ductwork system are among the top reasons homeowners seek professional duct cleaning services. Your air ducts provide a warm safe shelter for many pests, and they can easily find their way into your ducts and vents through narrow cracks or unsealed openings. Rats and mice may even chew through wood and wire in order to find safety, causing further damage to your home. But aside from the damage pests might cause in your air ducts, there are several health risks associated with ductwork pests:
Cleaning your air ducts is especially important after eliminating a roach infestation. Dead and decaying cockroaches in your air ducts can contribute to significant allergic reactions, which can grow more severe over time during continued exposure. Furthermore, humans can also be susceptible to allergens in the saliva or waste of cockroaches. These allergens are easily spread into the air from your ducts, and pose considerable health risks to anyone who lives in your home.
