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

It’s unpleasant to consider, but sometimes dust isn’t all that is in your duct system. You might have heard animal noises coming from air ducts and fear you have freeloading visitors. You can try and lure the little guys out but they may be nesting and refuse to leave their babies. Call Bob Brown Service Experts for a comprehensive duct cleaning and we will ensure your duct system is free of all these nasty house guests, such as:

Bugs and Insects

There are few things worse than aiming to kill a spider and watching is escape into your air vent. It’s impossible to get it now and all you can do is lay in your room and imagine it laying all those baby spiders. You may even swear you hear a few scampering around your duct system. Fear not. Bob Brown Service Experts will come see you and give you a complete duct cleaning and make sure that spider and any of her yucky friends are out of there. Babies, too.


When raccoons, mice, and other furry visitors find themselves in your duct system, generally 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 encounter, including holiday decorations or old toys you’re saving in your attic. Second, animals tend to chew, which can cause exposed wiring. That combined with the dried leaves and twigs they’re likely taking in to create a nest, and now there’s quite the fire risk in your duct system, your attic, or behind your walls. A complete duct cleaning can remove rodent droppings or nests, but you could also need to call a professional animal removal company to remove the rodents and maybe an electrician if there was any damage to the wiring.


Birds typically get into safe and warm 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 find birds in your vents, you’ll presumably end up with creepy-crawlies in your home. But that’s not the end of it. Birds create nests in your vents, and given the large amount of materials they use to construct said nest, it can wind up completely clogging a vent, preventing any airflow. As with rodents, a full duct cleaning from Bob Brown Service Experts can eliminate any droppings, feathers, or other possible illness-carrying leave-behinds. You may also need an expert animal removal company to actually remove the birds from air vents or attics.

Mice in Air Ducts

If there are mice in your home’s air ducts, you should take steps to remove them. Mice nibble on electrical wires and leave droppings 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 residence, they usually die in the ducts. This creates unhealthy living conditions, and you may notice an unsavory odor.

You may suspect mice due to the sounds you hear – some scratching and scrabbling inside air ducts. Or you could actually spot one making an escape through the heating vents in your home. You could 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 could trap them yourself, by placing traps just inside each vent and checking them each morning. Or you can pay for a professional exterminator.

If you’ve determined that the mice are gone, you will need to have your ducts expertly cleaned by an HVAC company. If mice have been there, they will have left mice refuse in your ducts. Mice leavings are toxic, and if you leave them in your ducts they can make your household sick. Bob Brown Service Experts offers duct cleaning services that will clean out most debris from your home’s ventilation system.
