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

It’s unpleasant to consider, but occasionally dust isn’t exclusively what is in your duct system. You might have heard animal noises coming from air ducts and fear you have unwelcome visitors. You can try and lure the little guys out but if they’re nesting they may not leave their babies. Call Service Experts Heating & Air Conditioning for a thorough duct cleaning and we will confirm your duct system is rid of all these unwelcome house guests, including:

Bugs and Insects

Not much is worse than trying to kill a spider and watching it run into your air vent. It’s out of reach now and all you can do is sit in your room and imagine it laying all those baby spiders. You may even swear you hear a couple scuttling around your duct system. Fear not. Service Experts Heating & Air Conditioning will come out and give you a complete duct cleaning and make sure that spider and any of her creepy-crawly friends are good and gone. Eggs, too.


When raccoons, mice, and other furry visitors find themselves in your duct system, commonly through openings in the duct work and cracks in the foundation or home exterior, it causes many issues. First, furry critters can leave droppings behind and can destroy anything they encounter, including seasonal 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 taking in to create a nest, and now you have quite the fire danger in your attic, duct system, and behind your walls. A full duct cleaning can get rid of rodent droppings or nests, but you might also need to call an expert wildlife removal company to remove the mice, squirrels, or other wildlife and maybe an electrician if there has been any damage to wiring.


Birds typically get into safe and sheltered places to nestand your air vents meet that criteria. Nests mean babies, which means they are feeding babies, and that means BUGS. If you find birds in your vents, you’ll probably end up with six-legged and eight-legged critters in your home. But that’s not all. Birds assemble nests in your vents, and given the vast amount of stuff they use to build said nest, it can wind up fully clogging a vent, preventing any airflow. As with mice, squirrels, etc., a full duct cleaning from Service Experts Heating & Air Conditioning can eliminate any droppings, feathers, or other likely illness-carrying leave-behinds. You may also need animal control to actually remove the birds from air vents or attics.

Mice in Air Ducts

If you have mice in your air ducts, you should take steps to quickly remove them. Mice nibble on electrical wires and leave feces like most rodents, but they also grow their population quickly. And when they run around in the ducts, treating it like the highway of your residence, they may die in there. This creates unhealthy living conditions, and you may notice unpleasant scents.

You might suspect mice because of the sounds you hear – lots of scratching and scrabbling along sheet metal. Or you might actually see one making an escape into the heating vents in your house. You may even confirm their passage by inspecting the ducts for mice leavings. If you think there’s mice you have a couple choices. You could trap them yourself, by placing traps inside each vent and checking them every morning. Or you can hire a specialist.

If you have verified that the mice are removed, you really should have your ductwork professionally cleaned by an HVAC company. If mice have been present, they will have left mice refuse in your ducts. Mice droppings are toxic, and if you ignore them in your ducts they can make you and your family sick. Service Experts Heating & Air Conditioning offers duct cleaning services that will eliminate most debris from your home’s ventilation system.
