Keeping out the rodents.
We have used ORIGINAL Bounce fabric softener sheets in our fifth wheel and our friends cottage to keep our the little critters. I put it everywhere when closing up. In cupboards, in refrigerator , stove, in corners, under furniture , between cushions etc. We have had extremely good results with this and it also leaves the rv smelling great. In the spring I just gather them up. You can still use them for the dryer but they will not suffice to use for the rodent problem again. The major scent will be gone but for the dryer, too much scent is not always a good thing. I have also heard about the essential oils of peppermint and that it works well also. With the fabric softeners, you can put them above curtains and in wheel wells also. Just thought we would tell you how it has worked for us.
