We have a little bit of a stink bug problem in my area. I live in a house surrounded by Evergreen trees. I probably have had about 2 dozen stink bugs in my house this fall. I just had someone caulk inside and out as well as put screens in the vents, etc. Someone introduced me to diamatious earth and I bought a large box. I read on your site that the DE has to remain dry to be effective in killing bugs. Do you have any idea of what I could do to keep it dry yet have it outside surrounding my house? I was thinking about some kind of tubing. Your help is much appreciated. Thanks.
