Aeracuras' all natural essential oil Rodent Repellent is effective in repelling vermin such as rats, mice, chipmunks, squirrels, moles, and shrews, (not the human kind -- they like this aroma).

You can put drops of oil in ductwork, pipe chases, entrances, garages, and basements to chase away rodents.  If you wish, you can place 2-3 drops on a cotton ball instead of directly on another surface.

Aeracuras' all natural essential oil Rodent Repellent has a pleasant (to human noses) mint aroma.
