Whatever the reason for using dishsoap, as a surfactant (works great) or as indicated above, (which I've never tried personally...only bugs I get are flies) be sure that it is not antibacterial. If it is an antibacterial soap, it will kill the bioactivity in your soil. Also, I could be wrong, but I believe some dishsoaps can be an unwanted source of various phosphates, so easy does it. :thumbsup:
