How to keep critters out of heat exhaust pipe
Question - how do you keep critters (mice and chipmunks) out of the Suburban furnace heat exhaust pipe?
We found lots of seeds & acorns in the heater in the spring. Its taken all summer to get the family of mice out of our 2014 Alpine and I don't want anyone else to move in over the winter, if you know what I mean.
Can we add a screen behind the outside plate or should we just stuff steel wool in the pipe when we close up for the season, and perhaps put a piece of duct tape over the outside too. We don't use the RV in the winter, but do put a cover over it for the brutal Minnesota winter..
Any advice is most appreciated.
Thx.
