Follow the Below Steps to prevent mice from entering your RV-

1. Find The Entrance Holes

If you are troubled with mice in your RV and looking for a way how to get mice out of the camper, you must first look for holes.  Remember, mice entering an RV through the door is rare. They will always find an alternative way to enter, like small holes in the pipe or walls. 

So, if you think your RV door has no gap to let a mouse enter, then you are wrong. Mice can find their way even from the tiniest hole in your van. Now, looking for the entrance holes of mice is easy if you know the trick. 

When looking for a hole in your RV, make sure you search and point out the minor holes. Because mice have flexible rib cages which allow them to squeeze through tiny holes. So, do not miss out on the little holes in your RV.

You can also follow the thumb rule to figure out the mouse holes. If a pencil is easily going through the holes, the mouse can also pass through that hole. Also, if a spot is equal to a dime’s size, a mouse can easily enter through that hole. 

Remember, you must look for the entrance holes outside and inside the RV. Be sure to search the below part of your RV. Mice are great climbers who can enter through the holes under the RV. After finding each spot, mark them with highlighting tapes or markers.

2. Cover Or Seal The Holes

Once you find the holes, it is time to cover them. Yes, you read it right! You have to cover the gaps so that the mice do not find their way to let in. However, do not worry because covering or patching up the holes is easy. 

You can quickly seal the holes using wall patches, spray foam wood filler, or steel wool. Firstly, wall patches are not perfect for all types of spots. If the gap is too small, then it is safe to use wall patches.

Next, if you use spray foam, simply spray it on the holes. Do not spray much because the foam will expand, so it is better to spray less. 

On the other hand, you can also use steel wool to seal the mice entrance of your RV. Steel wool is more effective than spray foam because mice find it harder to chew steel wool. It mainly helps to seal the openings permanently.

However, if you want to be extra safe, use spray foam and steel wool together. To do so, first, put the steel wool into the hole and then spray the foam. It will provide extra protection, and mice cannot chew and invade through double protection.

3. Cover The Vents

Other than little holes, mice can enter your RV through the air vents. Air vents remain open for proper ventilation, and mice take advantage of it. You cannot fully close the vents, but you can cover them with mesh wires from the outside so that mice do not get in and the air flows remain good.

Note: Hardware cloth is also a proper tool to cover the air vent of your RV.

4. Use Tubes Of Sheet Metal

Besides digging holes, mice are also well-known as great climbers. They can climb through anything they find. Remember, to get into your RV, they will climb over the tires, jack stands, and tubes. Are you now worried about how to keep mice from climbing tires? If so, this article has the perfect solution for you. 

One of the most effective ways to prevent mice from climbing tires and tubes is to use sheet metal. You can find galvanized sheet metal reasonably priced at your nearby hardware store. 

After you buy them, cut the sheet into long strips and make vertical tubes around the tires, tubes, and jack stands. Mice cannot climb the vertical tubes; remember to put the height to 8-10 inches. Also, there must not be any gaps between the tubes because even a tiny gap will help mice to climb the tire and waste all your efforts. Ensure you do this when you park your RV in one place for a long time.

5. Always Keep Your RV Clean

The more dirty your RV is, the more it attracts mice. So, the best way to prevent mice in your RV is to keep it clean. Ensure every RV corner is clean and there are no food scraps. 

Moreover, give special attention to the kitchen and cabinets. Mice tend to build their nest in the kitchen area because this is where they will get food. Also, do not store newspapers, clothes, or toilet paper in the RV because they are perfect materials to make a mouse nest. 

Furthermore, if you have kids, you have to be extra careful. Having kids means it is tough to keep the RV clean as they always keep throwing food here and there. You must always check under the cushions and couches if there are any food scraps under them. Because children tend to put their chocolate and chips under the pillows and behind the couches.

6. Use LED Lights To Deter Mice

Adding LED lights around and beneath the vehicle will make mice avoid the place. Mouse prefers dark areas to live in, and they cannot tolerate lights as they do not like exposure. 

So, placing LED lights under RV to keep mice away is efficient because the lights make them uncomfortable. As a result, they will stay away from your vehicle and won’t ruin your vacation. 

On top of that, the LED lights won’t bring any harm. Besides preventing mice, it makes your vehicle look nicer at night.

Keeping Ultrasonic electric repellent in your RV silently deters mice. It avoids the hassle, and you get a mice-free vehicle. Remember, do not put the device anywhere in your car. It is best to place it near any open entrance or door from where the mice try to enter the RV.
