not sure how many times I've posted the FRESH CAB product... but here goes again. 30 foot trailer use 3 sacs of their product one front rear and center. workds out to about 5 dollars a bag for piece of mind.
I used their bags last fall and no mice in my trailer nor my older home which always saw mice and teh 2 cats having a blast..
home made fixes may or not work.. and I hate moth ball smells.
