I have found these critters in my garden tube in my master. They seem to love it! We have not used the tub since we moved in this past January. I just put water in it when I clean it. I was told to use Home Defense to kill and keep away the spiders and ants we were having, so I tired spraying this in my tub. So far, so good. But it has only been a few days.
Janet ..did you ever get rid of those and if so how? i live in Northern NJ also and have the same problem.....
