How to use boric acid against bedbugs? - briefly
Apply a thin layer of food‑grade boric acid powder in cracks, seams, and around bed frames, then vacuum after 24–48 hours to remove residues and dead insects. Repeat the treatment every few weeks to disrupt the insects’ exoskeletons and prevent re‑infestation.
How to use boric acid against bedbugs? - in detail
Boric acid, a mild inorganic compound, acts as a stomach poison for bed bugs when ingested through contaminated surfaces. Its low volatility makes it suitable for targeted application in hidden habitats.
Use a food‑grade powder with particle size of 5 µm to 10 µm. Wear disposable gloves, open a window for ventilation, and keep the area free of food, clothing, and pets. Avoid direct contact with skin and eyes.
Application methods:
- Dusting: Lightly sprinkle the powder into cracks, crevices, baseboards, and the seams of furniture. Use a hand‑held duster or a brush to distribute an even layer no thicker than a film of flour.
- Mattress treatment: Remove all bedding, flip the mattress, and apply a thin dusting to the underside and the box‑spring frame. Do not place powder directly on sleeping surfaces.
- Trap preparation: Mix a small amount of boric acid with powdered sugar (1 part acid to 4 parts sugar) and place the mixture in shallow containers near known harborage zones. The sugar attracts bugs, while the acid delivers the lethal dose.
Safety measures:
- Seal treated areas with plastic sheeting for 24 hours to prevent accidental contact.
- Store remaining powder in a locked container, out of reach of children and animals.
- Do not apply to painted or varnished surfaces that may be damaged by the abrasive nature of the powder.
Monitoring:
- Inspect treated zones weekly using a flashlight. Reapply dust where residue has been disturbed or where new activity is observed.
- Continue treatment for at least four weeks, as bed bug life cycles span several days and eggs may hatch after initial exposure.
Effective control relies on thorough coverage of all harborages, regular reapplication, and strict adherence to safety protocols.
