WARNING!
Wrong! This is an irresponsible post! SILICA is in Diatomaceous Earth, NOT Silicon Dioxide!! DE "is almost pure silica (with some beneficial trace minerals); under a microscope, it looks like shards of glass (glass is made from silica). DE is totally nontoxic. There is no buildup of tolerance like there is to poisons because the method of killing is PHYSICAL, not chemical. On any beetle-type insect that has a carapace, like fleas and cockroaches, the DE works under the shell and punctures the body, which then dehydrates and the insect dies. "
