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

It’s not fun to think about, but occasionally dust isn’t all that is in your duct system. You might have heard animal noises coming from air ducts and fear you have freeloading guests. You can pull out all the stops to lure the creatures out but they may be nesting and refuse to leave their babies. Call Comfort Masters Service Experts for a comprehensive duct cleaning and we will make sure your duct system is free of all these uninvited house guests, such as:

Bugs and Insects

Nothing is worse than trying to kill a spider and seeing it escape into the air vent. It’s impossible to get it now and all you can do is lay in bed and imagine it laying all those spider eggs. You may even believe you hear a few scrambling around your duct system. Don’t worry. Comfort Masters Service Experts will come to your home and give you a full duct cleaning and make sure 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, usually through openings in the duct work and fractures in the foundation or home exterior, it causes several issues. First, rodents can leave droppings behind and can ruin anything they come across, including holiday decorations or old toys you’re saving in your attic. Second, animals tend to chew, which can cause exposed wiring. That mixed with the dried grass and leaves they’re likely carrying in to manufacture a nest, and now you have quite the fire danger in your duct system, your attic, or behind your walls. A professional duct cleaning can remove rodent droppings or nests, but you might also need to call an expert wildlife removal company to remove the rodents and perhaps an electrician if there was any wire damage.


Birds normally look for safe and warm places to nestand your air vents meet that criteria. Nests mean baby birds, which means they are finding food for babies, and that means BUGS. If you find birds in your vents, you’ll probably end up with creepy-crawlies in your home. But that’s not all. Birds construct nests in your vents, and given the large amount of stuff they use to construct said nest, it can end up fully clogging a vent, preventing any airflow. As with rodents, a professional duct cleaning from Comfort Masters Service Experts can eliminate any droppings, feathers, or other possible illness-carrying leave-behinds. You might also need a professional wildlife removal company to actually remove the birds from your vents or attics.

Mice in Air Ducts

If there are mice in the air ducts, you should take steps quickly to remove them. Mice nibble on wiring and leave feces like most rodents, but they also multiply quickly. And when they run around in the ducts, treating it like the beltway of your house, they eventually pass away inside. This creates an unsanitary situation, and you may notice an unsavory odor.

You may suspect mice due to the noises you hear – some scratching and scrabbling in ducts. Or you may actually see one making an escape into the heating vents in your walls. You might even confirm their status by inspecting the ducts for mice feces. Either way, if you suspect mice you have a couple choices. You could trap them yourself, by placing traps on the interior of each vent and checking them in the morning. Or you can pay for a specialist.

If you have verified that the mice are exterminated, you really should have your ductwork professionally cleaned by an HVAC company. If mice have been present, they will have left droppings in your ducts. Mice droppings are toxic, and if you ignore them in your ducts they can make you sick. Comfort Masters Service Experts offers duct cleaning services that will remove most debris from your home’s airways.
