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

You don’t want to think about it, but often times dust isn’t the only thing that is in your duct system. You might hear animal noises coming from air ducts and realize you have unwelcome visitors. You can try and lure the creatures out but they may not leave their babies if they are nesting. Call Jack Nelson Service Experts for a complete duct cleaning and we will ensure your duct system is free of all these unwanted house guests, such as:

Insects and Bugs

Nothing is worse than aiming to kill a spider and seeing it escape into the 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 scurrying around your duct system. Never fear. Jack Nelson Service Experts will come see you and give you a full duct cleaning and assure that spider and any of her bug friends are evicted. Eggs, too.


When rodents make their way into your duct system, commonly through openings in the duct work and breaks in the foundation or home exterior, it causes many issues. First, furry critters can leave droppings behind and can ruin anything they get into, including holiday decorations or old toys you’re saving in your attic. Second, those little guys tend to chew, which can result in exposed wiring. That combined with the dried leaves and twigs they’re likely taking in to manufacture a nest, and that creates quite the fire hazard in your attic, duct system, and behind your walls. A professional duct cleaning can get rid of 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 has been any damage to wiring.


Birds usually get into safe and sheltered places to nestand your air vents are perfect. Nests mean baby birds, which means they are finding food for babies, and that means BUGS. If you find birds in your vents, you’ll presumably end up with creepy-crawlies in your home. But that’s not all. Birds assemble nests in your vents, and given the vast amount of materials they use to assemble said nest, it can end up totally clogging a vent, stopping any airflow. As with our furry friends, a professional duct cleaning from Jack Nelson Service Experts can eliminate any droppings, feathers, or other possible illness-carrying leave-behinds. You may also need animal control to actually remove the birds from the vents or attics.

Mice in Air Ducts

If you have mice in your ductwork, you should take steps to quickly 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 road system of your residence, they may die in the ducts. This creates a health hazard, and you may notice an unsavory odor.

You probably think of mice because of the noise you hear – plenty of scratching and scrabbling inside ducts. Or you could actually see one making an escape into the heating vents in your home. You might even confirm their presence by inspecting the ducts for mice droppings. Either way, if you you’re worried you have mice you have two options. You can trap them yourself, by placing traps inside each vent and checking them each morning. Or you might decide to hire a professional exterminator.

After you’ve verified that the mice are exterminated, you will need to have your ducts expertly cleaned by an HVAC company. If mice have been present, they will have left mice refuse in your ducts. Mice droppings are toxic, and if you ignore them in your ducts they can make you and your family sick.
