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

It’s unpleasant to consider, but sometimes dust isn’t the only thing that is in your duct system. You might have heard animal noises coming from air ducts and notice you have unwelcome visitors. You can pull out all the stops to lure the little guys out but they may be nesting and refuse to leave their babies. Call Strand Brothers Service Experts for a complete duct cleaning and we will assure your duct system is free of all these unwanted house guests, including:

Insects and Bugs

Nothing is worse than trying to kill a spider and watching it run into the air vent. It’s impossible to get it now and all you can do is sit on the couch and imagine it laying all those spider eggs. You may even swear you hear some scrambling around your duct system. Never fear. Strand Brothers Service Experts will come see you and give you a full duct cleaning and assure that spider and any of her bug friends are evicted. Eggs, too.


When raccoons, mice, and other furry visitors find themselves in your duct system, commonly through gaps in the duct work and fractures in the foundation or home exterior, it causes many issues. First, wildlife can leave droppings behind and can tear up anything they come across, including holiday decorations or old toys you’re saving in your attic. Second, rodents tend to chew, which can result in exposed wiring. That combined with the dried leaves and twigs they’re likely carrying in to manufacture a nest, and that creates quite the fire danger in your duct system, your attic, or behind your walls. A complete duct cleaning can get rid of rodent droppings or nests, but you might also need to call a professional animal removal company to remove the furry visitors and possibly an electrician if there was any damage to the wiring.


Birds normally look for safe and dry places to nest, like your air vents. Nests mean eggs, which means they are finding food for babies, and that means BUGS. If you have birds in your vents, you’ll likely end up with six-legged and eight-legged critters in your home. But that’s not all. Birds create nests in your vents, and given the vast amount of materials they use to build said nest, it can result in completely clogging a vent, preventing any airflow. As with mice, squirrels, etc., a thorough duct cleaning from Strand Brothers Service Experts can remove any droppings, feathers, or other possible illness-carrying leave-behinds. You may also need a professional wildlife removal company to actually remove the birds from air vents or attics.

Mice in Air Ducts

If you have mice in your home’s ducts, you should take steps to quickly remove them. Mice chew through wiring and leave refuse like most rodents, but they also multiply quickly. And when they run around in the ducts, treating it like the road system of your home, they may die in there. This creates an unsanitary situation, and you may notice unpleasant scents.

You probably suspect mice because of the noises you hear – lots of scratching and scrabbling in walls. Or you could actually see one making an escape into the air vents in your house. You might even confirm their status by inspecting the ducts for mice droppings. Either way, if you think there’s mice you have two choices. You could trap them yourself, by setting traps just inside each duct and checking them in the morning. Or you could pay for a professional exterminator.

Once you have verified that the mice are removed, you should have your ductwork professionally cleaned by an HVAC company. If mice have been living in the walls, they will have left mice refuse in your ducts. Mice droppings are toxic, and if you don’t remove them from your ducts they can make your household sick. Strand Brothers Service Experts offers duct cleaning services that will eliminate most debris from your home’s airways.
