What is the name of a bedbug powder? - briefly

The most commonly sold bed‑bug powder is «DeltaDust», a diatomaceous‑earth formulation applied to cracks, seams and other hiding places. It kills insects by desiccating them on contact.

What is the name of a bedbug powder? - in detail

The powder most frequently cited for controlling bedbugs is diatomaceous earth. This natural, silica‑based substance consists of fossilized algae shells that abrade the insects’ exoskeletons, causing desiccation. It is sold under various brand names, but the generic term remains diatomaceous earth.

Other powder formulations include:

• Silica gel powder, marketed as «silica dust» or «silica aerogel». It works by absorbing lipids from the cuticle, leading to rapid water loss.
• Pyrethrin‑based powders, often labeled «pyrethrin dust». Pyrethrins are botanical insecticides that disrupt nervous system function. These products may contain synergists such as piperonyl‑butoxide to enhance efficacy.
• Boric acid powder, referred to as «borax dust». Boric acid interferes with the insect’s metabolic processes after ingestion or contact.

Key characteristics for each type:

1. Diatomaceous earth

   • Particle size: 5–10 µm.
   • Application: Light dusting on cracks, crevices, and mattress seams.
   • Safety: Non‑toxic to humans and pets when food‑grade grade is used; respiratory irritation possible if inhaled.

2. Silica gel powder

   • Particle size: ≤1 µm.
   • Application: Similar to diatomaceous earth, with emphasis on thorough coverage.
   • Safety: Low toxicity; prolonged inhalation may cause lung irritation.

3. Pyrethrin dust

   • Active ingredient: 0.5–2 % pyrethrins.
   • Application: Targeted treatment of hiding spots; avoid excessive dust to reduce residue.
   • Safety: Toxic to aquatic organisms; moderate toxicity to mammals; use protective equipment.

4. Boric acid powder

   • Concentration: 5–10 % boric acid.
   • Application: Spot treatment of infestations; effective when combined with other control methods.
   • Safety: Low acute toxicity; chronic exposure can affect kidneys; keep away from children and pets.

Effectiveness depends on proper application, environmental conditions, and integration with other control strategies such as heat treatment or vacuuming. Selecting the appropriate powder requires assessment of infestation severity, indoor air quality considerations, and regulatory restrictions on pesticide use.
