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

You don’t want to think about it, but occasionally dust isn’t exclusively what is in your duct system. You might hear animal noises coming from air ducts and fear you have unwanted visitors. You can try and lure the critters out but they may not leave their babies if they are nesting. Call Service Experts Heating & Air Conditioning for a complete duct cleaning and we will assure your duct system is rid of all these nasty house guests, such as:

Insects and Bugs

Not much is worse than trying to kill a spider and watching is escape into an air vent. It’s impossible to get it now and all you can do is lay in your room and imagine the spider laying all those spider eggs. You may even swear you hear some scuttling around your duct system. No worries. Service Experts Heating & Air Conditioning will come out and give you a complete duct cleaning and assure that spider and any of her yucky friends are evicted. Babies, too.


When raccoons, mice, and other furry visitors find themselves in your duct system, normally through holes in the duct work and fractures in the foundation or home exterior, it causes multiple issues. First, squirrels, mice, or raccoons can leave droppings behind and can ruin anything they encounter, including holiday decorations or old toys you’re saving in your attic. Second, animals tend to chew, which can result in exposed wiring. That mixed with the dried leaves and twigs they’re likely taking in to build a nest, and that creates quite the fire risk in your attic, behind your walls, and in your duct system. A good duct cleaning can remove rodent droppings or nests, but you could also need to call an expert wildlife removal company to remove the rodents and perhaps an electrician if there was any damage to the wiring.


Birds typically find safe and sheltered places to nest, like your air vents. Nests mean baby birds, which means they are bringing food to babies, and that means BUGS. If you discover birds in your vents, you’ll likely end up with creepy-crawlies in your home. But that’s not all. Birds assemble nests in your vents, and given the great amount of materials they use to build said nest, it can result in completely clogging a vent, stopping any airflow. As with mice, squirrels, etc., a thorough duct cleaning from Service Experts Heating & Air Conditioning can get rid of 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 air vents or attics.

Mice in Air Ducts

If you have mice in your ductwork, you should take steps to quickly remove them. Mice nibble on wires and leave refuse like all rodents, but they also add to their population quickly. And when they run around in the ducts, treating it like the road system of your home, they usually die in the ducts. This creates a health hazard, and you may notice an unsavory odor.

You might suspect mice because of the noises you hear – plenty of scratching and scrabbling inside ductwork. Or you could actually notice one making an escape through the vents in your house. You may even confirm their passage by inspecting the ducts for mice droppings. If you you’re worried you have mice you have two choices. You could trap them yourself, by setting traps on the interior of each vent and checking them in the morning. Or you might decide to pay for a specialist.

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