Squirrels are entering bottom of camper through hollow rear bumper. I have used moth cakes, steel wool and several products to discourage critters. Any suggestions? This design seems seriously fiawed to me.
Beware,
We had two squirrels get in to our basement in a National Park last year. In an area, I couldn't get to with out dropping the coroplast.
I first noticed it when our 12 volt components started going out one by one. Lights, fans etc.
Rodents will chew wires instinctively. They did a number on ours. It took me over 6 hours total to fix all the damage.
When I was a phone company repairman, about one in five trouble reports, was caused by rodents.
I couldn't get them out in any humane way, so I resorted to Decon rat trays. Decon dehydrates animals, so they go looking for water.
It stunned them enough, so that I found them laying in the cargo area and I was able to push them out with a stick.
They had gotten in through the cargo door when we were outside having a cold one, with the doors open.
Now I keep cargo doors shut unless I am standing next to them, if I suspect any rodents are in the area. Trace
