Grandpa Gus's Rodent Repellent Spray, Peppermint & Cinnamon Oil, Prevents Mouse/Rats from Nesting & Chewing on Wires, 16 fl oz (Pack of 1)

Product does not work!!! Came without sprayer nozzle. Also, sprayed copious amounts of product on engine over several days repeating each day. I saturated engine and engine wiring. Still, rat nests are being built in my car's engine. I am disappointed.

Great to use in the house because the aroma is wonderful, everyone's reactions are positive. Except for the mice. They are vacating. Good stuff!

I soaked cotton balls with this and have not seen mouse droppings in the normal places in over a week!Con: you have to apply more every few days since it's mostly water. You could buy peppermint and cinnamon oils and it's the same thing. This is in a super convenient spray bottle.

This is great stuff for those of us who own Kia's and Subaraus. It keeps the mice/squirrels away from the electronics and wiring in these cars if you use it judiciously! Would recommend to anyone who has to park outside and near a large fields' It works well with the soy based wiring used in most of the new cars/trucks.

I was incredulous of this product's effectiveness as I have found nothing as effective as the simplest spring wooden mouse traps - of course the killing and handling of dead mice is unpleasant so this seemed worth a try.In the latest instance:We found mouse droppings in our apartment and decided to give this a try in addition to other measures. After applying it to cotton disks and leaving them everywhere we thought the mouse was traveling, the place really smelled pungently of peppermint and cinnamon. The dog was sneezing. After a few days we weren't finding new droppings and didn't see the mouse, so we spent some time packing steel wool into every crevice we thought could be an entry point. We did not see the mouse again. My conclusion is that this was enough of a repellent for the mouse could go back to whatever apartment it came from, which gave us time to close all the entry points.In a past instance:We were living in a row house with pocket doors that rolled into the walls which proved to be an easy way for rodents to move from house to house. It was perhaps a renovation two doors down that sent mice looking for a new home. It was unclear if Grandpa Gus's was much of a deterrent in this case as after applying it liberally around the area on cotton balls more mice kept coming through the wall. We ended up using traps at the point of entry and caught probably 8 mice over a few weeks.Overall conclusion: this can be helpful in addition to other measures, but is not enough on it's own especially if you've got an issue with multiple mice.

Used as directed and so far it’s kept the mice away!

Works great!

Works as a dest to deterrent
