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

You don’t want to think about it, but often times dust isn’t all that is in your duct system. You might have heard animal noises coming from air ducts and fear you have unwanted tenants. You can attempt to lure the creatures out but if they’re nesting they may not leave their babies. Call Komfort Air Service Experts for a thorough duct cleaning and we will confirm your duct system is free of all these nasty house guests, including:

Insects and Bugs

Not much is worse than working 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 lie in bed and imagine the spider laying all those spider babies. You may even believe you hear a few scuttling around your duct system. Fear not. Komfort Air Service Experts will come to your home and give you a thorough duct cleaning and make sure that spider and any of her bug friends are out of there. The offspring, too.


When rodents make their way into your duct system, normally through gaps in the duct work and breaks in the foundation or home exterior, it causes many issues. First, rodents can leave droppings behind and can destroy anything they come across, including Christmas decorations or old toys you’re saving in your attic. Second, rodents tend to chew, which can leave you with exposed wiring. That mixed with the twigs and dried grass they’re likely carrying in to manufacture a nest, and that creates quite the fire risk in your attic, behind your walls, and in your duct system. A good duct cleaning can get rid of rodent droppings or nests, but you could also need to call an expert wildlife removal company to remove the furry visitors and maybe an electrician if there was any wire damage.


Birds typically look for safe and dry 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 find birds in your vents, you’ll likely end up with creepy-crawlies in your home. But that’s not the worst part. Birds construct nests in your vents, and given the great amount of materials they use to construct said nest, it can result in completely clogging a vent, obstructing any airflow. As with mice, squirrels, etc., a thorough duct cleaning from Komfort Air Service Experts can get rid of any droppings, feathers, or other potential 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’ve got mice in your ductwork, you should take steps to remove them. Mice chew through wires and leave refuse like most rodents, but they also grow their population quickly. And when they run around in the ducts, treating it like the road system of your residence, they eventually pass away inside. This creates an unsanitary situation, and you may notice unpleasant scents.

You may guess mice because of the sounds you hear – lots of scratching and scrabbling along ductwork. Or you may actually notice one making an escape through the heating vents in your home. You could even confirm their presence by inspecting the ducts for mice feces. Either way, if you suspect mice you have two options. You could trap them yourself, by setting traps on the interior of each vent and checking them in the morning. Or you might decide to hire a professional exterminator.

After you have determined that the mice are gone, you should have your ducts professionally cleaned by an HVAC company. If mice have been present, they will have left feces in your ducts. Mice leavings are toxic, and if you ignore them in your ducts they can make your household sick. Komfort Air Service Experts offers duct cleaning services that will clean out most debris from your home’s airways.
