For many years I used Bayer Advanced Complete Insect Killer as a dip to kill AEFW on SPS frags. Bayer is a garden insecticide and it will not only kill AEFW, but Red Bugs as well. But here is the thing, Bayer is hazardous to humans and, thus, you must be extremely careful when using the product as a dip. To be on the safe side it is a good idea to use latex gloves, a mask and protective eye wear.
Another downside to using Bayer is that the liquid is milky white. This makes it extremely difficult to spot any AEFW that may fall off a frag during the dipping process. Fortunately, other options besides Bayer exist. One is potassium chloride. If you own a water softener then you are already familiar with potassium chloride. MORE
