Yes, Alpine Dust is used in the wall voids. They walk across the dust, get it on each other and try dry out. Apply to cracks and crevices where evidence of bed bugs occurs. This includes bed frames, box springs, inside empty dressers, clothes closets, and carpet edges, high and low wall moldings and wallpaper edges. Do not use Alpine Dust on mattresses, pillows, bed linens or clothes. Reapply as necessary. Please let us know if you have any additional questions.
