I used to be in the habit of keeping my window partially open when parked inside my Garage/Shop. Stopped doing that when i was drinking out of my coffee cup while running errands one day and i had forgotten to close the flap on my cup before i got out to walk into Homedepot. Drank from it till i got home and found a mouse inside it when i opened the lid to wash it out. I since don't leave the window open more than 1/8 inch . Never had a mouse in my vehicles since.
Now that is disgusting. How much did you drink before you started tasting the fur...
This thread reminded me to resoak my repellent. I use peppermint essential oil soaked on cotton *****. A buddy told me they use that in their feed room. It seems to work. I started using it after one of those critters unalived himself somewhere in the truck. Never did find the carcass, but took a year to get rid of the smell.
I have also heard of the soap thing. We used a cheese grater and shredded up some Irish Spring to put in the pantry. That also seems to have worked.
Never do this, you are literally putting out an attractant (food). Yes it is poison but it will still call them in to eat.
I use a poison "bait" in critter-proof housings at my storage lot. When the bait is available, I've never had a mouse bother getting into the RV. When I was lax in refilling the housing, that's when I saw they got in.
Driving to work yesterday and out of the corner of my eye I see movement on the passenger floor. A mouse is chewing away at my sons applesauce pouch! The nerve of that thing to just come out in the open like that! Lol It was funny at first but then I started thinking about possible damage. So at that point the fight was on.....
LED overhead lights, a 110V like that one, plus some 12V plugs in ones inside the trucks that run off the truck batteries (because they're all on maintainers), and I have very few rodent problems on the ranch. But my barn cat population seems well fed, so maybe they get the credit. Figure it can't hurt, especially if you have access to 110V outlet wherever you're storing.
I use Victron solar charge controllers and 200-ish watt solar panels to charge 12V deep cycle batteries to run the LED lights and 12V deterrents in my tractor shed. Plus a dedicated MPPT charger for each machine battery. A lot better than Battery Tender branded, cost isn't bad compared to buying new batteries as often as I was.
