I keep my SUV in storage when I hit the road. First year they got the wires.
Second year all I did was throw the pellet packs of
Just One Bite under the car and around all the tires and one for good luck under the hood. Been going on 4 years in storage, bag under the hood never touched and no more chewed up wires.
If you get them around the tires before they climb up you won't have any dead bodies. I've yet to see any dead mice using this stuff, they eat it and fill up and move on because it doesn't kill them immediately.
"... consume a lethal dose in a single feeding, but it may take two or more days from time of bait consumption for them to die..."That's why I like this brand. Go to a farm store and get the Agricultural strength.
