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

It’s unpleasant to consider, but occasionally dust isn’t exclusively what is in your duct system. You might hear animal noises coming from air ducts and realize you have unwelcome visitors. You can pull out all the stops to lure the creatures out but they may not leave their babies if they are nesting. Call A1 Chesney Service Experts for a complete duct cleaning and we will make sure your duct system is free of all these unwanted house guests, including:

Insects and Bugs

Nothing is worse than working to kill a spider and watching is escape into your 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 babies. You may even think you hear a couple scrambling around your duct system. No worries. A1 Chesney Service Experts will come see you and give you a complete duct cleaning and assure that spider and any of her yucky friends are out of there. Babies, too.


When rodents make their way into your duct system, normally through holes in the duct work and cracks in the foundation or home exterior, it causes several issues. First, wildlife can leave droppings behind and can destroy anything they come across, including holiday decorations or baby toys you’re storing in your attic. Second, animals tend to chew, which can leave you with exposed wiring. That joined with the dried grass and leaves they’re likely taking in to create a nest, and now you have quite the fire danger in your duct system, your attic, or behind your walls. A good duct cleaning can remove rodent droppings or nests, but you may also need to call animal control to remove the rodents and perhaps an electrician if there was any wire damage.


Birds typically get into safe and dry 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 have birds in your vents, you’ll probably end up with six-legged and eight-legged critters in your home. But that’s not the end of it. Birds build nests in your vents, and given the large amount of leaves and grass they use to create said nest, it can result in completely clogging a vent, preventing any airflow. As with rodents, a professional duct cleaning from A1 Chesney Service Experts can remove any droppings, feathers, or other likely illness-carrying leave-behinds. You might 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 home’s ductwork, you should take steps to remove them. Mice gnaw electrical wires and leave droppings like all rodents, but they also grow their population quickly. And when they run around in the ducts, treating it like the road system of your house, they eventually die in the ducts. This creates a health hazard, and you may notice it due to the smell.

You probably suspect mice due to the noises you hear – lots of scratching and scrabbling inside air ducts. Or you could actually notice one making an escape through the vents in your walls. You could even confirm their presence by inspecting the ducts for mice droppings. Either way, if you you’re worried you have mice you have some choices. You may trap them yourself, by placing traps on the interior of each duct and checking them in the morning. Or you can pay for a professional exterminator.

If you’ve verified that the mice are gone, you should have your ductwork professionally cleaned by an HVAC company. If mice have been there, they will have left mice refuse in your ducts. Mice droppings are toxic, and if you ignore them in your ducts they can make you and your family sick.
