A whole lot of them in my house. I'm going to try, once again, to find boric acid at wal mart, and try the soap and water in a spray bottle--do I just spray the bathtub, kitchen and bathroom floors where they're most prevalent? I plan on squirting the boric acid in the nooks and crannies they crawl in. Husband is very careful about pesticides, but I read about the boric acid and it seems virtually harmless for humans. This should be enough right? I'm sick of them!
