How to Winterize An RV For Storage, Critter-Free

If you’re an avid RVer you will be putting your RV into winter storage. A critical component of winterizing your vehicle is keeping our mice.

But, as you may know, this isn’t as easy as just parking the RV, turning off the lights, and locking the doors. Not if you want to help ensure that everything is properly operational and critter free when you go to venture out again next season.

There are a number of great resources that detail all of the steps for properly winterizing your recreational vehicle. Many of these steps focus on protecting the RV plumbing system from freezing temperatures. This is important. No one wants to deal with the results of frozen water lines. 


Follow your RV owner’s manual for winterizing instructions and stock up on key supplies such as antifreeze, a water heater by-pass kit, a tank cleaning wand, and a water pump converter kit. If you’re a DIYer, and make the adjustments needed to put your mind at ease about any unwanted plumbing/water issues during the winter.

The Farmer’s Almanac is predicting a warmer and wetter winter again for 2018, except for the southwest of the US which will be colder than normal. While weather forecasting is not an exact science, you may want to take extra care to guard against critters that might seek shelter during a wet season.

Mice might sometimes be cute to look at. However, the damage they can cause is anything but cute. They have well-honed teeth that they like to use to chew on everything in sight, from food packages to stored items, to wiring.

In addition, they are also carriers of several parasites including lice, mites, fleas, and ticks. Plus, you didn’t buy that nice RV to be a rodent motel, so to keep rodents outside where they belong, be sure to:

  • Seal up all gaps, cracks, and holes that might allow for easy entry
  • Remove water sources and any vegetation from around your RV
  • Remove all food and food waste
  • And most importantly, use Grandpa Gus’s mouse repellent pouches or sprays to deter them from entering in the first place while getting the added benefit of keeping your RV smelling good.

Grandpa Gus products are an effective deterrent because the peppermint and cinnamon smell of our product works on the mouse’s olfactory glands to keep them at bay. These are all-natural ingredients that can safely be used in enclosed areas on wiring, baseboards, and countertops. It sure beats coming back to mouse droppings and/or mothball smells!

If it really is a rodent-attracting rainy winter, you may want to use some of our products in your home or cabin as well – effective and safe for people and pets!

"We used to have mice sneaking into our RV at least once a month before we got these. Haven't seen a mouse or droppings in years now!" - Bill (62, Idaho) 

So after your last 2018 RV adventure, be sure to prep the waterlines, seal up any cracks, remove any tempting food or water sources, and then generously place Grandpa Gus mice repellent products throughout your vehicle. The mice won’t be too happy about it, but you’ll be glad you did.

And when you get ready to head back out for more RV fun, don’t forget to check out Grandpa Gus’s tick and spider sprays as well.
