How to Keep Mice Out of Camper

It seems no one is exempt from mice infestation. These little pests are especially fond of campers and other recreational vehicles because they are often exposed to the outside elements, and there is plenty of food inside.

If you have this problem, take heart. Keeping mice out of your camper is really not that difficult.

The 7 tips below will help you keep mice out of your camper for good.

1. Store Your Camper on a Paved Surface

If at all possible, store your camper on a paved or hard surface. Don’t park it in a grassy or forested area. These places are the roaming grounds of mice and rats while they forage for food. There should be some kind of pavement between your parking area and the grass or trees.

2. Plug Any Holes Inside and Out

If you’ve just bought your camper, this is the first thing you should do. Inspect all areas of the camper and plug every hole that you see in it. In other words, check every nook and corner of your camper as well as all furniture and cabinets.

By inspecting the whole camper, you will be able to see every possible entry point that pests can use to enter the camper. A thorough inspection is the first important thing you can do to protect your camper from pests.

Seal holes the size of a dime from the inside. If it’s not too difficult for you to do, also seal the holes from the outside. Double sealing the holes makes it harder for pests to penetrate. Look for the entry points of wires and pipes into your camper, especially on the floor.

The best sealant you can use is the one with expanding foam, just like a tire sealant. You just need to shake the can of the sealant and squirt the liquid onto the hole. The liquid will turn into foam, which will harden and plug the hole.

But don’t apply too much goo to the hole. Apply just enough to get the holes sealed. To know how much to apply, try it first on anything that has a hole in it. If there is any excess foam, remove it at once. Once it hardens, it can be harder to remove.

Another sealant that you can use is a caulk that seals window joints and seams or leaks in piping. Caulks are also available in cans. They are squirted on the gaps, cracks, or holes to seal the item.

7. Don’t Store Food Inside Your Camper

Mice and other pests are always scavenging for food and foraging around to where they smell the scent of something they can eat. If you store food inside your camper even if you are not using it, you attract and invite them to your camper to check if there’s anything they can eat there.

What to Do If Mice Have Already Infested Your Camper?

Don’t get discouraged if you discover that mice have already invaded your camper. If you do the following things, they will disappear.

1. Use Mouse Traps

If you are reluctant to using poison in your camper, mice traps are a good alternative. They are somewhat gruesome if you think about it, but your health and the safety of your vehicle are at risk. There are three kinds of mice or mouse traps you can use:

  1. Standard spring trap
  2. Sticky paper
  3. Box trap

Standard Spring Trap

It is the old type of mouse trap you see in cartoon comic strips and movies. While it is somewhat gruesome, it is very effective in eliminating mice and reducing their brood.

Sticky Paper

This is one of the most convenient, non-bloody mice traps if you don’t like seeing blood. Just spread the sticky paper, put some leftover food on top, and then place it in a spot where you think mice are likely to go.

When they step on the sticky paper to get the food, they won’t be able to get out because they will be trapped in the strong glue. You have to dispose of the mice and the paper after that.

Box Trap

This trap is also effective in solving mice infestations. Put some food in the box trap to lure the mice in. Once the mouse is in, it will step onto something that will trip the box cover to shut close, trapping the mouse inside. You have to get rid of the mouse and maybe the box as well. But you can reuse the box by only getting rid of the mouse.

2. Use Rat or Mice Poison

Killing mice with poison is another option. The problem with this solution is that you won’t know where they’re at once they are all dead. You will surely be bothered by the stench of their rotting bodies. But you can’t find their bodies because you don’t know where they are holing.

One effective solution is to use a poison that weakens the mice and causes them to seek out the light when they are already weak. In this way, you won’t trouble yourself finding their bodies. They will be out there in the light once they are dead.

Mice or rat poisons are mostly available in powder form and are combined with food to attract rodents. So, be careful in spreading the poison. They should be placed in spots that small kids couldn’t reach.

3. Remove Food from Your Camper

Of course, you need food to sustain your body while you are out there camping. But storing food on your camper even if it is in storage is not a good practice. Food left in your camper will attract all kinds of pests, including mice and even rats. Remember, these creatures have a keen sense of smell.

If you think you will not be using your camper until the next month or two, get rid of all the food inside it. These are some of the food that you must pull out of your camper if you put it in storage:

  • Breakfast bars or health bars wrapped in paper or plastic
  • Flour or sugar in paper bags
  • Nuts and dried fruits in tin cans or cardboard boxes/cans
  • Coffee creamers (powder or liquid) in tin cans or plastic containers
  • Chips of any kind in plastic bags
  • Uncooked pasta in plastic or cardboard containers
