In another thread about skunks, someone suggested I put Moth Balls under the house to run off the skunks. My sister told me to use Moth balls to run off a snake once and we threw out about 12 balls near the barn and it smelled to high heaven. I know the Moth balls will melt in the rain, if outside. But, if I toss a few under the house to run off that skunk, how long will the Moth Ball smell last under the house? Do Moth balls evaporate or rot over time? I know the skunk smell is too nasty to even use the Cabin now but I would not want to replace the skunk smell only to have another stinky odor that I cannot get rid of either. Thanks.
