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

It’s unpleasant to consider, but often times dust isn’t all that is in your duct system. You might have heard animal noises coming from air ducts and notice you have freeloading guests. You can try and lure the creatures out but they may be nesting and refuse to leave their babies. Call Peitz Service Experts for a thorough duct cleaning and we will make sure your duct system is clear of all these nasty house guests, for instance:

Insects and Bugs

Not much is worse than working to kill a spider and watching is escape into the air vent. It’s impossible to get it now and all you can do is sit in your room and imagine the thing laying all those spider babies. You may even swear you hear a couple scampering around your duct system. Don’t worry. Peitz Service Experts will come see you and give you a full duct cleaning and ensure that spider and any of her bug friends are evicted. The offspring, too.


When rodents make their way into your duct system, generally through gaps in the duct work and cracks 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 seasonal decorations or old toys you’re saving in your attic. Second, those little guys tend to chew, which can result in exposed wiring. That joined with the twigs and dried grass they’re likely carrying in to create a nest, and now there’s quite the fire danger in your duct system, your attic, or behind your walls. A full duct cleaning can get rid of rodent droppings or nests, but you might also need to call an expert wildlife removal company to remove the rodents and perhaps an electrician if there was any wire damage.


Birds usually get into safe and warm places to nest, like your air vents. Nests mean babies, which means they are bringing food to 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 construct nests in your vents, and given the great amount of stuff they use to assemble said nest, it can wind up totally clogging a vent, preventing any airflow. As with our furry friends, a professional duct cleaning from Peitz Service Experts can remove any droppings, feathers, or other possible illness-carrying leave-behinds. You could also need an expert animal removal company to actually remove the birds from your vents or attics.

Mice in Air Ducts

If there are mice in the air ducts, you should take steps quickly to remove them. Mice chew through wiring and leave droppings like all rodents, but they also add to their population quickly. And when they run around in the ducts, treating it like the beltway of your home, they eventually die in the ducts. This creates a health hazard, and you may notice it due to the smell.

You probably guess mice because of the noise you hear – some scratching and scrabbling along ducts. Or you might actually spot one making an escape through the heating vents in your home. You may even confirm their presence by inspecting the ducts for mice droppings. If you you’re worried you have mice you have two options. You could trap them yourself, by setting traps just inside each vent and checking them each morning. Or you could hire a professional exterminator.

Once you’ve determined that the mice are removed, you really should have your ducts thoroughly 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 you sick. Peitz Service Experts offers duct cleaning services that will clean out most debris from your home’s ventilation system.
