BonideBat Magic Bat Repellent, Pack of 4 Ready-to-Use Peppermint Oil Scent Packs for Long Lasting Indoor Bat Control

While this is meant for indoor use, I found it worked well enough to move a few bats from roosting above a window. I was able to hang a satchel in the apex of the roof above the window and after a few nights the bat droppings stopped.

Scent was strong initially, but less than a day later, you could not smell them. Didn't work for me!

Great product. I had a few bats trying to make a home in the attic. I had the attic screened off, but they still made a home. In one night they were gone. Here are the pictures. Highly recommend.

Did not seem to help with the bay problem we have in an outbuilding. Did not work for us.

After having spent years setting up traps all over the place for what I thought was mice crawling all over our cabin, turns out that it was really bats that were leaving tiny droppings that looks just like mouse ones. The problem is that it is difficult to keep bats out of spaces such as old drafty cabins as they can get through extremely tight spaces. Per the scientific literature out there, the best bets to keep bats out are sealing the space and lighting the space at night. Some recommend napthalene/benzene, but no thanks on putting carcinogens in a fishing cabin. Left with little choice, I tried this product. Each box comes with four packs which smell like peppermint, and placed them near the rafters of the ceiling. The amount of bat poop dropped dramatically, but is not entirely gone. I will keep using them as they are not too expensive and seem to be having an effect.

A+++ Very effective with pleasant peppermint smell!The bats hate it ;)

Mostly a gimmick. It works until the bats just find another area to roost. You would have to hang a thousand of these under you deck to keep all bats away, all the time.

Worked last summer to keep a bat out of our one shutter. This year the bat returned to same shutter. So will do it again. It’s worth the price since it lasts the entire summer.
