Dust

Desiccant Dusts

• Formulation: Made from diatomaceous earth (DE) or silica gel.
• Mode of Action:
  • Works by absorbing the waxy outer layer of an insect’s exoskeleton, causing dehydration and death.
  • No chemical toxicity—kills insects mechanically.
• Benefits:
  • Long-lasting, doesn’t break down easily.
  • Safe for use in sensitive areas (food storage, pet bedding).
  • Effective against ants, cockroaches, bed bugs, fleas, and stored product pests.

Chemical Insecticide Dusts

• Formulation: Fine powders containing synthetic insecticides (e.g., pyrethroids like deltamethrin, cyfluthrin, or carbamates).
• Mode of Action:
  • Affects the nervous system of insects on contact.
  • Residual control—insects pick up the dust and transfer it to nests or harborage areas.
• Benefits:
  • Extended residual activity (weeks to months).
  • Penetrates deep cracks, wall voids, and hidden spaces.
  • Less likely to be ingested by non-target animals than baits.
• Common Uses: Crack and crevice treatments, void applications, attics, and wall spaces.

Bait Dusts

• Formulation: Combines toxicant with food-based attractants in a dust form.
• Mode of Action:
  • Insects ingest the dust, leading to delayed mortality (ideal for colony control).
• Benefits:
  • Effective for social insects like ants and cockroaches.
  • Can be applied in hard-to-reach spaces where liquid or granular baits aren’t practical.

Botanical & Natural Dusts

• Formulation: Plant-based insecticides (e.g., pyrethrum, neem, essential oils) in dust form.
• Mode of Action:
  • Disrupts insect nervous or hormonal systems.
  • May act as a repellent in some cases.
• Benefits:
  • Eco-friendly and low toxicity to humans and pets.
  • Safe for organic pest control strategies.

General Advantages of Insecticide Dusts

* Long residual life—remains effective for weeks or months.
* Good for voids and hidden areas—where sprays can’t reach.
* Less risk of chemical breakdown—compared to liquids.
* Low odor and dry formulation—won’t stain surfaces.

Common Uses: Crack and crevice treatments, wall voids, attics, electrical outlets, behind appliances, and around pest entry points.

Dusts are great non-repellent options for pest control professionals, especially for cockroaches, ants, bed bugs, fleas, and stored product pests.
