just that there is a house diagonal behind me and i have a fenced in back yard, to space from hers to ours, what i want to know when summer comes will those suckers travel in her yard to mine then to my home? i dont want to deal with them ever again had a horrible experience at my old house four years ago and now we own a home and i just dont want to ever go back to it again. so if they can, is there anything i could line my yards with to prevent them traveling into my yard?
