Description
What Pests Does Delta Dust® Control?
Delta Dust is labeled to control a wide range of structural pests, including:
- Ants
- Cockroaches
- Spiders
- Silverfish
- Earwigs
- Wasps (void and nest applications)
- Beetles
- Other crawling insects
Because pests must walk through the dust, Delta Dust is especially effective against insects that hide during the day and emerge at night.
How Delta Dust® Insecticide Works
After application, Delta Dust forms a residual dust barrier inside treated areas. When insects crawl through it:
- Dust particles cling to the insect’s body
- The active ingredient is absorbed through contact
- The insect dies shortly after exposure
- Other insects entering the area are also controlled
Because Delta Dust is non-repellent, insects do not avoid treated areas, increasing overall exposure and effectiveness.
How Long Does Delta Dust® Take to Work?
Delta Dust begins working soon after insects contact the treated dust. Most users notice a reduction in pest activity within 24–48 hours, with continued population decline over the following several days.
Unlike sprays that lose effectiveness quickly, Delta Dust continues killing insects for months in dry, undisturbed locations.
How Long Does Delta Dust® Last?
One of Delta Dust’s biggest advantages is longevity.
- In dry wall voids, attics, crawl spaces, and electrical boxes, Delta Dust can remain effective for months or longer
- As long as the dust stays dry and undisturbed, it continues working
This makes Delta Dust ideal for preventative treatments and long-term structural protection.
Where to Apply Delta Dust®
Delta Dust is commonly applied to:
- Wall voids
- Attics and crawl spaces
- Electrical outlets and switch boxes
- Cracks and crevices
- Plumbing penetrations
- Structural voids and gaps
It is not intended for broadcast application and should be applied lightly using a hand duster or bulb duster.
Delta Dust® vs Liquid Insecticides
Compared to sprays:
- Lasts significantly longer in protected areas
- Reaches hidden nesting and travel zones
- Does not break down from light or heat as quickly
Compared to aerosol dusts:
- More professional-grade
- Better residual longevity
- Designed for structural pest control programs
Delta Dust is often used as a supplement to liquid treatments, not a replacement.
Is Delta Dust® Safe to Use in Homes?
When applied according to the label, Delta Dust is safe for residential use. It should only be applied to voids and inaccessible areas, not open surfaces. People and pets should avoid contact with treated areas.
Who Should Use Delta Dust®?
Delta Dust is ideal for:
- Persistent ant or roach problems
- Spider infestations in wall voids
- Preventative attic or crawl space treatments
- DIY users who want professional-grade tools
- Situations where sprays cannot reach or last
If pests are hiding where sprays can’t reach, Delta Dust is the solution.
