Safer Brand Diatomaceous Earth Powder, Ant, Crawling Insect, and Bed Bug Killer
The safest silverfish killer makes it to the top, and it's Safer Brand Diatomaceous Earth. It is made with the crushed and powdered shells of fossilized diatoms that are safe to use, non-toxic and can be used around kids and pets. Simply sprinkle the diatomaceous earth around known silverfish habitats and let it work. Although the particles resemble dust to us, they are actually tiny razor blades to insects. When they either ingest the particles or merely walk over them, the diatomaceous earth slices through their exoskeleton which causes the insect to dehydrate. It works best when distributed in dry areas, and can be used both indoors and outdoors with equal effectiveness.
