π¬ How It Works
Delta Dust contains the same active ingredient as Suspend SC (deltamethrin) but in a dust formulation with a critical advantage: waterproof formulation. It is the only EPA-registered insecticide dust that remains effective after getting wet β making it ideal for crawl spaces, attic vents, outdoor wall voids, and other areas where moisture exposure is likely.
The dust particles cling to insects' bodies and legs as they walk through treated areas, delivering the pyrethroid through contact. Particularly effective applied directly into wasp or yellow jacket nests in wall voids.
βοΈ Mixing & Application Rates
Dry dust β apply with bellows duster. No dilution needed.
Void injection β wasps/yellow jackets
2β3 puffs per nest entrance
Apply at night when wasps are inactive. Inject directly into the nest entrance using a bellows duster. Delta Dust's waterproof property makes it ideal for outdoor nest voids that experience weather exposure. Seal the entry after 48 hours (after activity ceases).
Cockroach void/crack treatment
Light to moderate dusting
Apply behind refrigerators, under dishwashers, inside wall voids via outlet covers. Delta Dust is preferred over non-waterproof dusts in areas with potential moisture (under sinks, in bathrooms).
Crawl space perimeter
Light dusting on horizontal surfaces
Apply around perimeter and entry points. Waterproof formulation maintains effectiveness through moisture fluctuations in crawl spaces.
β Frequently Asked Questions
Q: Is delta dust safe for pets?
Follow the product label. Keep pets out of treated areas until completely dried (2β4 hours for sprays). Once dry, treated surfaces pose minimal risk to dogs and cats.
Q: Can I use delta dust indoors?
Check the specific product label β formulations vary. Baits and dusts often have indoor labeling; concentrates and granulars are typically outdoor.
Q: How long does delta dust last after application?
Residual varies by formulation, surface type, weather, and UV exposure. Indoor applications last longer than outdoor. Check the product label for re-application intervals.
Q: What should I do if exposed?
Remove contaminated clothing, wash skin with soap and water. For eye contact, rinse 15β20 minutes. For ingestion or severe symptoms, call Poison Control (1-800-222-1222). Have the product label available.
