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

It’s unpleasant to consider, but often times dust isn’t the only thing that is in your duct system. You may hear animal noises coming from air ducts and realize you have unwelcome visitors. You can try and lure the critters out but they may be nesting and refuse to leave their babies. Call R & M Climate Control Service Experts for a comprehensive duct cleaning and we will ensure your duct system is clear of all these uninvited house guests, such as:

Bugs and Insects

Nothing is worse than working to kill a spider and watching is escape into an air vent. It’s out of reach now and all you can do is sit in your room and imagine the thing laying all those spider babies. You may even believe you hear some scuttling around your duct system. Don’t worry. R & M Climate Control Service Experts will come see you and give you a thorough duct cleaning and ensure that spider and any of her yucky friends are out of there. The offspring, too.


When rats, squirrels, and other wildlife make a home in your duct system, generally through holes in the duct work and breaks in the foundation or home exterior, it causes multiple issues. First, rodents can leave droppings behind and can tear up 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 leave you with exposed wiring. That combined with the twigs and dried grass they’re likely bringing in to manufacture a nest, and now you have quite the fire hazard in your attic, duct system, and behind your walls. A professional duct cleaning can get rid of rodent droppings or nests, but you could also need to call a professional animal removal company to remove the mice, squirrels, or other wildlife and perhaps an electrician if there has been any damage to wiring.


Birds typically look for safe and dry places to nestand your air vents meet that criteria. 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 six-legged and eight-legged critters in your home. But that’s not the end of it. Birds assemble nests in your vents, and given the large amount of leaves and grass they use to assemble said nest, it can end up totally clogging a vent, obstructing any airflow. As with mice, squirrels, etc., a completely duct cleaning from R & M Climate Control Service Experts can eliminate 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 air vents or attics.

Mice in Air Ducts

If there are mice in your air ducts, you should take steps quickly to remove them. Mice nibble on wires and leave feces like all rodents, but they also add to their population quickly. And when they run around in the ducts, treating it like the highway of your home, they usually die in the ducts. This creates a health hazard, and you may notice it due to the smell.

You might suspect mice due to the noises you hear – some scratching and scrabbling inside air ducts. Or you could actually spot one making an escape into the vents in your home. You could even confirm their passage by inspecting the ducts for mice feces. Either way, if you you’re worried you have mice you have a couple options. You may trap them yourself, by placing traps inside each vent and checking them in the morning. Or you could pay for a specialist.

After you’ve determined that the mice are removed, you should have your air ducts thoroughly cleaned by an HVAC company. If mice have been there, they will have left feces in your ducts. Mice droppings are toxic, and if you don’t remove them from your ducts they can make you sick. R & M Climate Control Service Experts offers duct cleaning services that will clean out most debris from your home’s ventilation system.
