The Eaton Insecticide Duster is used with products like Pyrodust or Diatomaceous Earth. This item improves the way dust is applied by finely layering in within cracks, crevices and other areas.
Insecticidal Dust must be applied very smoothly. Just as fine as dust accumulating on a table, for instance. Insects will not walk through a mound of dust. Insects only get the dust on themselves when walking over a delicate amount. The two ways dust kills insects is when they groom themselves and ingest it or the product creating micro cuts.
