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

You don’t want to think about it, but often times dust isn’t exclusively what is in your duct system. You might have heard animal noises coming from air ducts and notice you have unwelcome tenants. You can attempt to lure the creatures out but if they’re nesting they may not leave their babies. Call Knochelmann Service Experts for a complete duct cleaning and we will assure your duct system is clear of all these uninvited house guests, such as:


Not much is worse than trying to kill a spider and seeing it escape into an air vent. It’s impossible to get it now and all you can do is lay in bed and imagine the spider laying all those spider eggs. You may even believe you hear a few scrambling around your duct system. No worries. Knochelmann Service Experts will come out and give you a full duct cleaning and ensure that spider and any of her creepy-crawly friends are good and gone. The offspring, too.


When rodents make their way into your duct system, generally through gaps in the duct work and fractures in the foundation or home exterior, it causes several issues. First, squirrels, mice, or raccoons can leave droppings behind and can destroy anything they get into, including seasonal decorations or old toys you’re saving in your attic. Second, animals tend to chew, which can result in exposed wiring. That mixed with the twigs and dried grass they’re likely taking in to create a nest, and now you have quite the fire danger in your attic, behind your walls, and in your duct system. A professional duct cleaning can get rid of rodent droppings or nests, but you may also need to call an expert wildlife removal company to remove the rodents and maybe an electrician if there was any damage to the wiring.


Birds typically find safe and sheltered places to nestand your air vents meet that criteria. Nests mean baby birds, which means they are feeding babies, and that means BUGS. If you discover birds in your vents, you’ll probably end up with bugs in your home. But that’s not the worst part. Birds construct nests in your vents, and given the vast amount of stuff they use to construct said nest, it can wind up completely clogging a vent, stopping any airflow. As with rodents, a professional duct cleaning from Knochelmann Service Experts can remove any droppings, feathers, or other potential illness-carrying leave-behinds. You could 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 air ducts, you should take steps quickly to remove them. Mice gnaw wiring and leave refuse 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 home, they eventually die in the ducts. This creates an unsanitary situation, and you may notice an unsavory odor.

You may suspect mice because of the noise you hear – some scratching and scrabbling along sheet metal. Or you might actually see one making an escape into the air vents in your walls. You could even confirm their passage by inspecting the ducts for mice feces. If you suspect mice you have some choices. You may trap them yourself, by setting traps on the interior of each duct and checking them each morning. Or you could pay for a professional exterminator.

Once you have verified that the mice are exterminated, you will need to have your ductwork professionally cleaned by an HVAC company. If mice have been there, they will have left feces in your ducts. Mice leavings are toxic, and if you ignore them in your ducts they can make you sick. Knochelmann Service Experts offers duct cleaning services that will eliminate most debris from your home’s ventilation system.
