YES. The handling of those chemical can cause cancer, however we have gloves and other gear that keeps the chemicals work on the bugs. Bedbugs are up more than 300% in past few years, and it is due to filth and importing of them from airplanes, hotels, and other places infested to government agencies, other hotels/motels, and into places set up to hold illegal immigrants.
Diatomaceous Earth is a natural product (ground up shells) that penetrates the majority of bug shells, and works on all types of bugs, spiders, and creep things. In the garden or the home, just vacuum up each week, and replace for a month, and bug free! Hard to do in a Hotel... white powder looks suspicious. LOL
