How To Keep Mice Out of Your RV (For Good!)

This post may contain affiliate links.

Whether you are a full-time RVer or putting your RV away for the winter, mice are always unwelcome! Don’t underestimate the lengths these critters will go through to get in either. We recently had mice in our RV and could not figure out how they were getting in. After trying a few different methods we eventually caught three! Below is a list of the proven methods on how to keep mice out of your RV.

Proven Methods to Keep Mice out of Your RV

These methods have been proven to keep mice out of your RV. These tried and true techniques are popular in the RV community.

Kill Traps

These can include snap traps, electrical traps, and glue traps. While I am not against killing a mouse that has entered your RV, I am against glue traps. They prolong death and some mice might even chew off their own limbs to get out. That’s just sad and gross.

Catch and Release Traps

If you do not want to kill a mouse but are interested in kicking it out of your RV, then catch and release traps are for you.

We use catch and release traps when we are boondocking. We used this method to evict two of the three mice that were in our RV (the third was stubborn and we resorted to a snap trap for him, RIP little guy). Just be sure to release the mouse far away from your RV otherwise they just might come back.

Blocking Holes

You can take preventative measures by blocking all of the holes, gaps, and cracks into your RV with mouse foam sealant. Be sure to hunt down every gap in your RV, as mice can fit through a hole the size of a dime!

Peppermint Spray

If you’d prefer a more holistic method then a peppermint spray is a good choice. Spray this product outside to keep mice out of your RV. You can also take peppermint oil-soaked cotton balls and place them all around your RV.

Hire an Exterminator

If all else fails, resort to hiring an exterminator. Allowing a mouse problem to go on for too long can cause serious damage to your RV and can end up costing you a ton in repairs. If you can’t keep mice out of your RV yourself it’s best to bring in an expert.

Important Warning: Don’t Use Poison!

I’d like to step on my soapbox real quick: we are against all poison options when it comes to pest control. Mice are food for owls, coyotes, cats, mountain lions, and others. When you poison a mouse you are possibly poisoning any of these animals.

In California, there is a real problem of mountain lions dying from mouse and rat poison. This particular example is what led us to become aware of this issue and advocate against poison.

Old Wives’ Tales to Keep Mice out of Your RV

With that said let’s jump into the old wives’ tales of how to keep mice out of your RV. We can’t speak to them ourselves since we opted not to try any of them. That’s not to say they haven’t worked for some but there’s no guarantee they will work for you.

  • Irish Soap – The rumor is to place unwrapped bars of Irish Soap around your RV. Apparently, mice do not like the smell so they will stay away.
  • Dryer Sheets – We’ve heard that placing dryer sheets on the floor will keep mice out of your RV. The story behind this is that mice use their sense of smell to navigate back the way they came. Therefore, the dryer sheets are too strong for them and they can’t find their way back.
  • Steel Wool – Now, steel wool almost made the Proven Methods list but we heard too many failed stories to put it there. The method is to plug up any holes with steel wool as mice don’t like metal. If we were going to try any of the old wives’ tales, this would be the one.
  • Moth Balls – This method is to place mothballs around your RV and in your storage compartments. We found out it’s actually illegal to use mothballs for anything other than their intended use, as they are considered a poison… and you all know how we feel about poison.

Those are all of the proven methods we know of to keep mice out of your RV. Ever since we got our Battle Born Batteries installed we try to boondock as much as possible, which means we are more likely to encounter unwelcome guests.

In our opinion, there’s nothing better than a good old fashion trap. We prefer to use catch and release traps but will resort to snap traps if they refuse to vacate the premises. What methods have worked for you to keep mice out of your RV?
