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

It’s not fun to think about, but sometimes dust isn’t all that is in your duct system. You may hear animal noises coming from air ducts and fear you have unwelcome visitors. You can pull out all the stops to lure the critters out but they may be nesting and refuse to leave their babies. Call TML Service Experts for a complete duct cleaning and we will assure your duct system is clear of all these unwelcome house guests, such as:


Not much is worse than aiming to kill a spider and seeing it run into your 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 believe you hear a few scurrying around your duct system. Fear not. TML Service Experts will come see you and give you a thorough duct cleaning and assure that spider and any of her creepy-crawly friends are out of there. The offspring, too.


When rats, squirrels, and other wildlife make a home in your duct system, commonly through holes in the duct work and fractures in the foundation or home exterior, it causes multiple issues. First, squirrels, mice, or raccoons can leave droppings behind and can destroy anything they encounter, including Christmas decorations or baby toys you’re storing in your attic. Second, rodents tend to chew, which can result in exposed wiring. That joined 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 attic, duct system, and behind your walls. A full duct cleaning can remove rodent droppings or nests, but you could also need to call animal control to remove the mice, squirrels, or other wildlife and possibly an electrician if there was any damage to the wiring.


Birds usually get into safe and sheltered places to nestand your air vents are perfect. Nests mean baby birds, which means they are bringing food to babies, and that means BUGS. If you discover birds in your vents, you’ll likely end up with creepy-crawlies in your home. But that’s not the worst part. Birds create nests in your vents, and given the large amount of leaves and grass they use to construct said nest, it can result in fully clogging a vent, stopping any airflow. As with our furry friends, a completely duct cleaning from TML Service Experts can get rid of any droppings, feathers, or other possible illness-carrying leave-behinds. You might also need animal control to actually remove the birds from your vents or attics.

Mice in Air Ducts

If you’ve got mice in the air ducts, you should take steps to remove them. Mice nibble on wires and leave refuse like all rodents, but they also multiply 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 unhealthy living conditions, and you may notice unpleasant scents.

You probably suspect mice from the noises you hear – lots of scratching and scrabbling in walls. Or you may actually see one making an escape through the heating vents in your walls. You may even confirm their status by inspecting the ducts for mice feces. Either way, if you think there’s mice you have two choices. You could trap them yourself, by setting traps on the interior of each vent and checking them in the morning. Or you could contract a professional exterminator.

After you’ve verified that the mice are exterminated, you really should have your air ducts thoroughly cleaned by an HVAC company. If mice have been there, they will have left droppings in your ducts. Mice feces are toxic, and if you don’t remove them from your ducts they can make you sick. TML Service Experts offers duct cleaning services that will eliminate most debris from your home’s ventilation system.
