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

It’s unpleasant to consider, but occasionally dust isn’t all that is in your duct system. You may hear animal noises coming from air ducts and realize you have freeloading visitors. You can pull out all the stops to lure the little guys 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 free of all these uninvited house guests, for instance:

Bugs and Insects

There are few things worse than working to kill a spider and watching is escape into the air vent. It’s impossible to get it now and all you can do is lie in bed and imagine the spider laying all those baby spiders. You may even think you hear a couple scampering around your duct system. Don’t worry. Service Experts Heating & Air Conditioning will come see you and give you a thorough duct cleaning and assure that spider and any of her yucky friends are evicted. Eggs, too.


When rats, squirrels, and other wildlife make a home in your duct system, normally through openings in the duct work and cracks in the foundation or home exterior, it causes many issues. First, rodents can leave droppings behind and can destroy anything they encounter, including Christmas decorations or old toys you’re saving in your attic. Second, those little guys tend to chew, which can result in exposed wiring. That combined with the dried grass and leaves they’re likely carrying in to create a nest, and now there’s quite the fire risk in your attic, behind your walls, and in your duct system. A complete duct cleaning can remove rodent droppings or nests, but you may also need to call a professional animal removal company to remove the rodents and possibly an electrician if there has been any damage to wiring.


Birds usually get into safe and warm places to nestand your air vents are perfect. Nests mean babies, which means they are finding food for babies, and that means BUGS. If you find birds in your vents, you’ll presumably end up with creepy-crawlies in your home. But that’s not all. Birds create nests in your vents, and given the great amount of leaves and grass they use to build said nest, it can end up fully clogging a vent, stopping any airflow. As with mice, squirrels, etc., a completely duct cleaning from Service Experts Heating & Air Conditioning can get rid of any droppings, feathers, or other likely illness-carrying leave-behinds. You may also need an expert animal removal company to actually remove the birds from your vents or attics.

Mice in Air Ducts

If you’ve got mice in the ductwork, you should take steps to remove them. Mice nibble on wires and leave refuse like most rodents, but they also add to their population quickly. And when they run around in the ducts, treating it like the beltway of your house, they usually pass away inside. This creates a health hazard, and you may notice an unsavory odor.

You probably guess mice because of the sounds you hear – lots of scratching and scrabbling in sheet metal. Or you could actually notice one making an escape through the vents in your walls. You may even confirm their status by inspecting the ducts for mice leavings. Either way, if you suspect mice you have some options. You can trap them yourself, by placing traps inside each duct and checking them every morning. Or you can hire a pest control company.

If you have determined that the mice are gone, you really should have your air ducts expertly cleaned by an HVAC company. If mice have been present, they will have left droppings in your ducts. Mice leavings are toxic, and if you don’t remove them from your ducts they can make you sick. Service Experts Heating & Air Conditioning offers duct cleaning services that will remove most debris from your home’s airways.
