Squirrels

An air rifle and a good recipe...would be a “two for one”! ;)

Squirrels are rats with better press agents. But I have to agree, your problem sounds more like the work of their smaller relative, the mouse. With squirrels, you would likely find larger holes chewed out, twigs and nuts squirreled away (pun intended) and a whole lot of the outside brought inside. You have to go republican on squirrels and build a wall, deterrence is generally not effective.

Pure Peppermint Oil soaked cotton balls in your answer. Has worked for us for over 10 years, no mice.

I stayed at Ft. Desoto and noticed a plethora of squirrels and birds on the roof. Even think two holes were started by birds, none the less I bought a plastic owl at Home Depot and put it on a pole near the roof...the problem quickly disappeared.

Perhaps a few near your rig would help.

I would guess mice. Regardless though you need to seal ALL openings. Deterrents simply dont work. The only sure fire way is stopping them getting in.

That sounds like mice. Check all your drawers for a little nest. We had the problem and put original Irish Spring all over the place, especially under the drawers. Never had a problem since.

If you are sure you have squirrels maybe this woudl work.
