Some research has also found that desiccant dusts that dehydrate bugs to death, like diatomaceous earth and silica gel, can be effective at controlling bed bug infestations (silica gel in
If you want to test silica gel then find a small packet of silica gel desiccant that is commonly packed with lots of products to absorb moisture. Crush up the beads in the packet to a fine powder
Both silica gel and diatomaceous earth (DE) kill insects by removing a portion of the razor-thin, waxy outer coating that helps them conserve moisture. As a result, they desiccate and die from dehydration. Like super-fine sandpaper, DE acts principally by abrading the protective outer layer of wax as the insect crawls over or through the particles.
However, silica gel is great for getting rid of these bugs because it actually removes the think protective outer layer of bed bugs that help them conserve body moisture, resulting in faster absorption and faster effect.
Many cat owners use cat litter to get rid of bed bugs. Cat litter is nothing but silica gel crystals. You can crush the litter into a fine powder and sprinkle it around your bed, furniture, box springs etc. Bed bugs come in contact with the litter and the crystals shred their insides causing bed bugs' exoskeleton to get ripped off.
The findings clearly show that silica gel is a more potent bed bug killer than diatomaceous earth. Abbreviated exposures (as brief as a few seconds) to barely visible deposits resulted in 100 percent mortality of adult bed bugs.
