Squirrels like to do that, they like to chew !I feel like I'm comfortable on borrowed time with my Heat/AC system. The air handler was born in 1985 and the outside unit
was a replacement 16 years ago. Both run 24/7 the
year round here in Florida. But to make sure they get all the TLC they need I have them cleaned and maintained twice a year.
So far no uninvited residents, but I do notice that the
plastic cover of the the flexible natural gas hose feeding my
Generac has been totally eaten away by a mammal with
a strange taste. The gas man says it's still safe.
Around here it is hard to keep the aluminum ties for the chain link fence on, they are always chewing on them too.
I had a picnic table since 1996. It made out of marine grade wood that has sat out back since I bought it.
Some guy hand made it, he has been building these for a long time. Good quality work.
Now I know it is old but those damn squirrels been chewing at the cross brackets underneath for years.
All the brackets are almost gone now.
If not for that the table would have lasted many more years.
Squirrels got into an attic in a garage down the street and were chewing on the electric wires, burnt down the garage !
Around here it is open season on them, BB pellet guns work nice if the bleeding hearts don't see you. :smokin:
Bottom line is that they like to chew! Not to eat just to chew.
