A mouse may be small, but it’s the last thing you want to see in your house. Mice are cunning and find ways to enter your home by any means necessary to look for food. So, can mice get in through a dryer vent?

Mice can get into your house through a dryer vent if there are cracks in the opening on your exterior wall. Pack the cracks with steel wool and seal them with silicone caulk to make sure the opening is tight enough to keep mice out. Place ultrasonic mouse repellents along your exterior walls and put mouse traps on the ground in front of the vent.

Mice will also stay away from your dryer vent if you put cayenne pepper and peppermint oil on the ground in front of the dryer vent. Regularly use dryer sheets, as mice hate the smell and it can repel them. Follow along as we explore everything you need to know about how mice get in through dryer vents and see how you can keep them away.

Can Mice Get Inside A Dryer?

Mice can get inside your dryer in many cases. They typically make their way into the dryer through the vent. This can understandably startle any homeowner when they open their dryer and find a mouse. Not only is this scary, but it’s also unsanitary and dangerous.

Bugs and small rodents are the most common pests that you can find in your dryer. Dryer vents at most homes open to the outdoors to release air. This provides an easy entry point for pests to get into your dryer.

How To Keep Mice Out Of Dryer Vents

Whether it be reinforcing the vent or setting out traps, there are several ways to keep mice out of your dryer vent. There are several natural remedies you can use as well. Let’s look at the best ways to keep mice out of your dryer vent.

1. Seal Cracks

Mice are more likely to enter your dryer vent if it isn’t sealed properly. Go outside and find where your dryer vent ends. Weakened and cracked dryer vent flaps will let pests into your dryer.

Some homeowners mistakenly try to seal the cracks with silicone caulk. However, that only works well if you first patch the cracks with steel wool. The steel wool will provide a nice barrier and the silicone caulk will keep it in place.

Insert steel wool into the weak points at the end of your dryer vent flap. Pack the steel wool tightly and make sure that it is sealed. You can secure the steel wool with staples if it struggles to lay flat.

2. Dryer Sheets

Mice have an incredible sense of smell. You can use that to your advantage to repel mice and keep them out of your dryer vent. Mice hate chemical smells and strong fragrances, such as dryer sheets.

Not only do dryer sheets make your clothes feel soft and smell good, but they can also repel mice. Put a few dryer sheets in with each load of laundry. The smell will circulate throughout your dryer and the vent shaft.

This smell is faint by the time it exits your vent, but mice have a strong enough sense of smell that they can detect it. Use as many fragrant dryer sheets as possible for the best results to repel mice.

3. Peppermint Oil

Peppermint oil is one of the best ways to naturally keep mice out of your dryer vent. Mice are attracted to the warmth and odors coming out of the dryer vent unless you use dryer sheets, that is. With that said, they hate the odor of peppermint oil, and you can use it to keep them away.

Scatter some peppermint oil along the perimeter of your house. Concentrate the peppermint oil in the area near your dryer vent for the best results. Not only will it deter mice, but peppermint oil can also repel spiders, ticks, fleas, and cockroaches.

4. Mouse Traps

While most homeowners put mouse traps inside their houses, they are equally effective outside. Mice get into your dryer by traveling through the vent via the opening outdoors. Luckily, you can keep mice out of your dryer vent if you strategically place mouse traps along the wall by the dryer vent.

You will have the best results if you use mouse traps that are camouflaged. Mouse traps that are shaped like rocks or pieces of wood are more likely to attract mice, especially if they contain bait. Check the mouse traps regularly, empty them, and set them back up to catch more mice!

5. Cayenne Pepper

Cayenne pepper is another natural way to repel mice. They hate the smell and taste of cayenne pepper, and they are likely to stay away from your dryer vent and house when they detect it. Cayenne pepper can also keep spiders, ants, and beetles away from your home.

Spread some cayenne pepper along your home’s exterior wall and on the ground in front of the dryer vent opening. This is a great long-term solution, as nearby pests will gradually learn to stay away from the vent, especially if you regularly add more cayenne pepper.

6. Ultrasonic Mouse Repellent

An ultrasonic mouse repellent is a great way to keep mice off your property. These devices emit a frequency that is unpleasant for mice as well as other rodents and deer. They offer some of the quickest results and it only takes between 24 and 48 hours to scare the mice off your property.

Evenly distribute a few ultrasonic mouse-repellent devices along your home’s exterior walls for the best results. Make sure to put one in front of the dryer so that mice don’t avoid the devices around your house and look for solace in the vent. You can typically buy up to 6 ultrasonic mouse-repellent devices for $20-$25.

How Do I Know If An Animal Is In My Dryer Vent?

There are several ways to tell if an animal is in your dryer vent, but excess heat is the easiest way. An animal such as a mouse or shrew will create a blockage within your dryer vent. This blockage will trap hot air and eventually cause the dryer to overheat as the warmth struggles to leave.

You may also notice a burning smell that can tell you there is a blockage. Depending on how long the animal has been stuck, you may also notice a foul odor that indicates it is decaying within your dryer vent. If you notice the stench of decay, you should stop using your dryer immediately and contact an HVAC professional.

They have the tools necessary to remove the animal from the dryer vent without damaging it. In many cases, they will be able to clean the dryer vent as well. You can also tell that there is an animal in your dryer vent if you hear banging and thumping sounds when you are near the machine.

Summing It Up

Mice can get in through your dryer vent, especially if there is an opening. Check the end of your dryer vent on the outside of your house and look for cracks. Patch any cracks with steel wool and silicone caulk to keep mice, birds, and other pests out of your dryer vent.

You can naturally keep mice out of your dryer vent if you put cayenne pepper or peppermint oil along the exterior wall where your dryer vent ends. Otherwise, you can use ultrasonic mouse-repellent devices and mouse traps to repel mice.
