Great Stuff Alternative?

I am wondering if anyone has found a better alternative for sealing the camper against mice than the Great Stuff Insulating Foam Sealant. Great Stuff really is great, but it is messy, hard to control, permanently stains clothing, and worst of all seems to be a single use item for about $7 per can. The application straw now has a little tab to bend the straw back and park it, but this will not provide a good way to store the can between uses. It just dries out and becomes useless.

BTW, Great Stuff Pro Dispensing Gun Cleaner works well for cleanup if you use it right away, especially for tools and if you get some on yourself accidentally. It seems to be mostly acetone, and it doesn't work at all after the Great Stuff is dry. I've used the cleaner successfully to flush the application straw but the aerosol can itself must be cleaned thoroughly at it's opening and I've had mixed success at this. I think I've successfully re-used a can for a second time only once in about 3 tries.

I'm not asking for suggestions like steel wool and dryer sheets. Please only respond if you've found something better than Great Stuff for physically permanently mouse-proofing and sealing your camper.

I did some work under the kitchen sink and right now it appears that it is going to cost me $7 for a single-use can Great Stuff to finish the job.

Thanks for the additional knowledge - wasn't aware there was such a product for cleaning

Great Stuff can be used over IF you clean the nozzle. I blow it out with an air hose then clean it with lacquer thinner. Even then it’s a little iffy.

I have never tried to clean one but I do buy extra ones, 5 for five bucks. I leave the cured one on and put a new one on when needed, always works & you get to use the whole can. You can find them on ebay & amazon.

I also order extra nozzles. It is some aggravating stuff, but good stuff. I haven’t ever heard of an alternative, but would be interesting.
And remember, Great Stuff comes in the color of Black, if you didn’t know. It looks just like factory.

I use pond foam. They use it in between the rocks to hold them in place. It is 100% water proof and is close cell formula and is black in color and stronger then great stuff. You can get at some of the H\D not all of them carry it. Or can go to a pond supply store.

Gorilla tape on a cleaned surface. I applied it on the underside of the trailer where ever there was an opening. Still holding after 8 years of travel. Also under the kitchen sink.

RVing for over 13 yrs and our camper is stored on our farm, in the farm tool shed while not in use. We use pure mint flavoring saturated on cotton balls inside and in hatches and even on the farm and have not had mouse 1! Its cheap, easy to do, leaves no mess, and has a clean smell.
We tell people all the time and they never believe us.....until they get burned with all those other "solutions" and try it, makes a believer every time!

I found the mice were getting in through my vent on my steps. I pulled them off and stapled some metal door screen behind them and screw them back on.

We had bees come in through there one year and did the same with screening.
