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

You don’t want to think about it, but occasionally 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 pull out all the stops to lure the critters out but they may be nesting and refuse to leave their babies. Call Midland Air Service Experts for a thorough duct cleaning and we will ensure your duct system is free of all these unwelcome house guests, including:

Bugs and Insects

Not much is worse than trying to kill a spider and watching it run into your air vent. You can’t get to it now and all you can do is sit on the couch and imagine the thing laying all those spider babies. You may even swear you hear a couple scrambling around your duct system. Don’t worry. Midland Air Service Experts will come see you and give you a complete duct cleaning and assure that spider and any of her creepy-crawly friends are evicted. Eggs, too.


When raccoons, mice, and other furry visitors find themselves in your duct system, normally through holes in the duct work and breaks in the foundation or home exterior, it causes multiple issues. First, furry critters can leave droppings behind and can ruin anything they get into, including seasonal decorations or old toys you’re saving in your attic. Second, animals tend to chew, which can cause exposed wiring. That combined with the twigs and dried grass they’re likely carrying 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 complete duct cleaning can eliminate rodent droppings or nests, but you could also need to call an expert wildlife removal company to remove the mice, squirrels, or other wildlife and perhaps an electrician if there was any damage to the wiring.


Birds typically get into safe and sheltered places to nestand your air vents meet that criteria. Nests mean baby birds, which means they are finding food for babies, and that means BUGS. If you discover birds in your vents, you’ll likely end up with bugs 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 wind up completely clogging a vent, obstructing any airflow. As with rodents, a professional duct cleaning from Midland Air Service Experts can eliminate any droppings, feathers, or other potential illness-carrying leave-behinds. You might also need a professional wildlife removal company to actually remove the birds from the vents or attics.

Mice in Air Ducts

If there are mice in your home’s air ducts, you should take steps quickly to remove them. Mice chew through electrical wires and leave droppings like most rodents, but they also add to their population quickly. And when they run around in the ducts, treating it like the beltway of your residence, they eventually die in the ducts. This creates unhealthy living conditions, and you may notice an unsavory odor.

You probably suspect mice because of the sounds you hear – some scratching and scrabbling along ducts. Or you might actually notice one making an escape through the air vents in your home. You could even confirm their presence by inspecting the ducts for mice droppings. If you suspect mice you have a couple choices. You could trap them yourself, by placing traps just inside each vent and checking them each morning. Or you could contract a professional exterminator.

Once you have determined that the mice are exterminated, you should have your ductwork professionally cleaned by an HVAC company. If mice have been there, they will have left droppings in your ducts. Mice droppings are toxic, and if you ignore them in your ducts they can make you sick. Midland Air Service Experts offers duct cleaning services that will clean out most debris from your home’s air ducts.
