Thanks for your comment rejuvenation! Food grade DE is of course not a poison per se, and I am aware that some people actually take it as a mineral supplement and for other health benefits. However, if it's being used for insecticide purposes, it's best to keep pets and children away as it's not a good idea to breathe in the dust while it's being applied. Hope the isopropyl works well for you. Let me know how it goes. Thanks
