The product seems to work. I bought your product for it's residual ( or long term effect), so it will take some time for a thorough review. My only question is why are these bugs so prevalent now. I'm 70 years old and I had never knew these insects existed!!! So why now?? Not being elitist, but I wonder if it has anything to do with people from all over the world settling in America or perhaps it's because more Americans are traveling abroad. I would like to know why they are so prevalent.
