How do you cover vents to keep mice out?

Use steel wool (mice can't chew through it) and silicone caulk around the edges of the outside dryer vent and to fill other small cracks or openings you may find (don't seal up the vent opening because the heat needs to get out!). This is easy enough to DIY, but a repairman or HVAC specialist can do this, too.

Home / Blog / How to Get Rid Of Mice in Dryer Vents and Mouse Proof Your Dryer How to Get Rid Of Mice in Dryer Vents and Mouse Proof Your Dryer

By: EarthKind

On a cold day, is there anything better than putting on your favorite sweater or blanket fresh out of the dryer while it’s still warm? Unfortunately, mice enjoy the warmth of your clothes dryer just as much as you do. For rodents looking for a warm place to wait out the cold, a dryer vent is one of the easiest ways to get inside your cozy home.

Can Mice Get In Through Dryer Vents?

Yes, they sure can! Mice, along with other animals and pests, use household dryer vents as a pathway to get inside your home. Most homes with a laundry dryer inside have vents on the outside where the heat escapes. If the outside vent is uncovered or damaged, household pests can easily get inside. Once they enter through the vent, they can chew through the flexible tubing that connects to the actual appliance, giving them free access to the rest of your house. A few common reasons for mice getting into these vents are that the vent tube has a hole in it, the vent tube is not properly sealed against the appliance or wall, or the vent flapper on the outside of the house isn’t working properly (or it’s missing entirely). The vent flapper is a common culprit. As vent covers get old, the flaps can stop working, and that’s often one of the main reasons why rodents and bugs get into vents.

Signs You Have a Rodent in Your Dryer Vent

Here are some clues that you may have this problem in your home: Strange noises such as squeaking, scratching, scurrying or thumping sounds near the washer and dryer.

Inefficient or ineffective performance of your appliance.

Your dryer smells like urine.

Unpleasant odors.

Finding small black pellets, similar to rice in size and shape – these are mouse droppings . Broken or damaged vent covers on the exterior of your home or building.

Broken or damaged dryer vent hose.

Problems This Can Cause

If mice or any other animal takes up residence in your laundry vent, you’ll be facing a long laundry list of problems. This can certainly cause issues and could eventually lead to ruining your dryer. The phrase ‘quiet as a mouse’ is a lie, and when the sounds of noisy rodents are amplified by the thin metal and hollow sound effects of a vent, you’ll know why. The appliance’s efficiency will suffer if the vent is obstructed by a mouse nest or any rodent-related debris. The risk of fire increases when there are airflow blockages, as well. There are thousands of dryer fires annually, and failure to clean the lint is a leading cause of fire.

All that built-up dryer lint isn’t just a potential fire hazard, it can also create a pest haven. Pests coming through the dryer exhaust vent would be very happy to find an abundant supply of soft nesting material. Rodents love to chew all the time and will gnaw on electrical cables and wiring which is what could also result in a house fire. Other issues include the diseases rodents can transmit, the terrible smell that will result if a rodent dies in a hard-to-reach area, and the overall “ick” factor of dealing with this problem.

Mouse-Proof Dryer Vents and Laundry Rooms

Homeowners can help prevent this issue by spending a few moments rodent-proofing their laundry area. The best way to get rid of mice is to keep them from getting in, which can save you time and money in the end. Here are some tips on how to mouse-proof your dryer vent: Do an annual cleaning of your vent (along with a lint check each time you use the appliance). This is great to prevent general lint buildup (which can cause fires), but also to check for signs of rodents, birds, or bugs getting into the vent throughout the year. Clean up rodent attractants such as standing water, pet food, birdseed, and other food sources in this area. Seal up potential entry points ; make sure the vent hood is in good repair, doors, and windows shut tightly, and that there are no gaping cracks or holes along the building foundation. The outside opening of the vent is especially vulnerable but can be covered with a wire mesh cover available at most hardware stores. One thing to note is that dryer screens can cause faster lint buildup, which can be a fire hazard . Use steel wool (mice can’t chew through it) and silicone caulk around the edges of the outside dryer vent and to fill other small cracks or openings you may find (don’t seal up the vent opening because the heat needs to get out!). This is easy enough to DIY, but a repairman or HVAC specialist can do this, too. Use a rodent repellent around your home to keep mice and rats out. You can purchase specialty products designed specifically to keep critters out, such as screens or mouse-proof dryer vent covers.

How to Clean Up After an Infestation

If you had mice, or any other rodent living in your vent, the vent tube is likely full of gross droppings, nesting material, food crumbs, and terrible odors. We don’t recommend cleaning the vent hose. The best thing you can do is fully replace it. They aren’t too expensive and are easily found at hardware stores. It’s also important to clean the internal areas of the dryer where mice might have traveled, otherwise you might have to live with a terrible smell for months. You’ll need to unplug and pull out the unit to get access. Where the tube connects to the back of the dryer, use a sturdy pair of gloves to reach in and pull out any lint or leftover debris. You might need to remove the front and rear panels to get full access. Be careful, because you might find a dead mouse or disease-carrying droppings in there! We highly recommend wearing a mask. Mice can’t usually get through the ventilation system of your dryer from the lint trap and into the drum, so that shouldn’t be a problem, but look for signs just to be sure. You should also clean and sanitize the vent where the tube connects to the house and leads outside.

Prevent Them From Coming Back With Repellent

Getting rid of mice is critical for your own health and safety. Preventing pest problems and infestations from happening again is important to protect your appliances and save you from expensive repair bills and replacement costs. Stay Away® Rodent Repellent is 100% effective, guaranteed. Unlike lethal traps or poisons, this scent-based repellent is a pest control method that is made with botanical ingredients. Mice follow their noses to find food and to detect danger — the fresh scent of essential oils in Stay Away® overwhelms their highly sensitive scent receptors, causing them to flee the area. Place the pouches wherever you have seen signs of rodent activity. Leave the pouches in place for a few days to allow the mice to escape, then inspect your dryer vent and surrounding area to seal up any entry points so pests can’t get inside again. Shop Stay Away® Rodent online or at a store near you.
