For years we've scattered these odoriferous sheets--with their sickly sweet aroma--under the hoods of machines and vehicles.
During that time, they have appeared to keep the pack rats away.
But are all pack rats (aka Eastern Woodrats, Neotoma floridana) repelled by Bounce dryer sheets?
While cleaning out an old shed, I found several pack rat nests festively adorned with Bounce dryer sheets.
I removed the nests but saved the sheets that were still in good condition, placing about 50 of them in a pail on a shelf.
I returned the next day and found all 50 sheets in a space between wall and roof--the beginnings of a new nest.
I removed the sheets altogether and Mr. and/or Mrs. Pack Rat haven't returned.
If they do, there are two live traps waiting for them.
Most pack rats use a generic scaffolding of leaves and sticks, but some are great specialists when it comes to toppings. We have found nests that were topped with nothing but soybeans; nothing but corn cobs--dog food--cat food--and toys. My friend Mary McCoy, while doing field work, found a nest of nothing but rabbits' feet!
The shed rats love Bounce.
If we find them in the live traps, there is transport awaiting them to the far reaches of the pasture.
The last thing we need close to home, where our engines and electrical wires are protected by dryer sheets, are pack rats that specialize in dryer sheets!
