What's Crawling Around in Your Home's Air Ducts?

You don’t want to think about it, but occasionally dust isn’t all that is in your duct system. You might hear animal noises coming from air ducts and realize you have unwanted visitors. You can try and lure the little guys out but if they’re nesting they may not leave their babies. Call Donelson Air Service Experts for a complete duct cleaning and we will make sure your duct system is clear of all these nasty house guests, including:

Bugs and Insects

Not much is worse than working to kill a spider and watching is escape into the air vent. You can’t get to it now and all you can do is sit in your room and imagine the spider laying all those spider babies. You may even believe you hear a few racing around your duct system. Don’t worry. Donelson Air Service Experts will come see you and give you a complete duct cleaning and ensure that spider and any of her yucky friends are out of there. Eggs, too.


When rodents make their way into your duct system, commonly through holes in the duct work and cracks in the foundation or home exterior, it causes several issues. First, rodents can leave droppings behind and can ruin anything they come across, including Christmas decorations or old toys you’re saving in your attic. Second, those little guys tend to chew, which can cause exposed wiring. That joined with the twigs and dried grass they’re likely carrying in to build a nest, and now you have quite the fire risk in your duct system, your attic, or behind your walls. A full duct cleaning can remove rodent droppings or nests, but you might also need to call animal control to remove the mice, squirrels, or other wildlife and maybe an electrician if there has been any damage to wiring.


Birds usually get into safe and sheltered places to nestand your air vents are perfect. Nests mean eggs, which means they are bringing food to babies, and that means BUGS. If you have birds in your vents, you’ll likely end up with six-legged and eight-legged critters in your home. But that’s not all. Birds create nests in your vents, and given the large amount of materials they use to assemble said nest, it can wind up totally clogging a vent, obstructing any airflow. As with rodents, a full duct cleaning from Donelson Air Service Experts can remove any droppings, feathers, or other likely illness-carrying leave-behinds. You could also need an expert animal removal company to actually remove the birds from the vents or attics.

Mice in Air Ducts

If there are mice in your ductwork, you should take steps to quickly remove them. Mice gnaw electrical wires and leave feces like all rodents, but they also grow their population quickly. And when they run around in the ducts, treating it like the highway of your home, they usually pass away inside. This creates unhealthy living conditions, and you may notice an unsavory odor.

You probably suspect mice due to the noise you hear – plenty of scratching and scrabbling in air ducts. Or you may actually spot one making an escape into the air vents in your walls. You may even confirm their presence by inspecting the ducts for mice droppings. Either way, if you you’re worried you have mice you have a couple options. You may trap them yourself, by setting traps on the interior of each duct and checking them in the morning. Or you can hire a pest control company.

If you’ve determined that the mice are gone, you will need to have your air ducts professionally cleaned by an HVAC company. If mice have been present, they will have left droppings in your ducts. Mice feces are toxic, and if you don’t remove them from your ducts they can make you sick. Donelson Air Service Experts offers duct cleaning services that will eliminate most debris from your home’s airways.
