If you cover, I've used mothballs for years. Works like a charm.

I use mint oil.  I soak a couple cotton balls and place them where I don’t want mice

Wow, hard to argue with that video clip...

I’ve always been of the understanding that mice have sensitive sniffers, and avoid any strong odor.  

In the video clip the mice were taking bites out of the Irish Spring soap.  

I don’t put Irish Spring soap shavings in my boat, but the clip has me wondering about how effective anything is with a strong odor i.e. dryer sheets, peppermint oil, lavender, cedar chips etc.  

I will say lavender has been working well for me, maybe I’m just lucky, or maybe mice despise lavender lol

Menards has the lavender wicks as shown below, on sale thru 11-9.     1.99 Ea.       I bought 6.   I didn’t take the seal off, only the cap.  I’ll re- use them next season.  CARPIO

I googled the lavender packets up and it appears that there’s a few options.  Any specific type?
