The Swimming Pool variety of DE it has been processed, and is some cases chemicals added and the edges are not as sharp. Use the Horticultural or "natural" type. This has not been processed, the edges on the shells are still sharp and it will not harm your kids, dogs, cats, horses, etc.... DE is actually the shells/exoskeletons of tiny diatoms. the edges are extremely sharp, but small. as insects like pill bugs travel across it their exoskeletons are cut and they eventually dry out and die. this stuff is good (to get rid of) for all insects.

Thank you for the DE explanation. It made sense. I had already used some of the swimming pool DE on a few ant beds I saw. It reminded me of flour. It wasn't effective at all and now I understand why. I did use a little bit of orange oil in a gallon of water on the ant beds and it really worked great. Thanks again.
