Rodents and small animals often look for warm places to nest, and the HVAC system in your Sarasota, Florida, home is the perfect cozy hideout. To find out if your home has attracted some unwelcome critters, here are some common signs of a pest infestation in your HVAC system.

Foul Odors

If you notice a pungent smell emanating from your air vents, it’s a sign that animal urine, rotting food, or dead carcasses are littered throughout the HVAC system. Decaying rodents have a distinctive smell — you’ll know when you smell it. Not only is a putrid smell unpleasant, but it’s also unhygienic. Bacteria from urine, feces, and rotting carcasses will circulate through the HVAC system and affect your home’s indoor air quality and your health.

Rodent Droppings

At the first sign of tiny black rodent droppings, take immediate action to contain the problem before a full-blown infestation occurs. Mice and rats can breed at an alarming rate. It’s always best to call a professional exterminator.

Scurrying Noises

There’s no sound more chilling in the dead of the night than the pitter patter of tiny feet as they scurry across the attic floor. You wonder if you’re dreaming or imagining it. So you listen again, almost ceasing breathing as you strain your ears. There it is again. Scurrying, squeaking, gnawing, and scratching are all conclusive evidence that you’ve got pests living in the attic.

Reduced HVAC Efficiency

Rodents are notorious chewers and can cause serious damage to HVAC ductwork and electrical wiring. When rodents move in, they will chew up all types of materials, including insulation and duct tape, to use to build nests. Insects, cockroaches, spiders, and wasps also gain entry to ductwork. Wasp nests and spider webs reduce air flow. If you notice your HVAC system’s performance has declined, inspect your ducts for signs of insects or rodents.
