How to use absolute for bedbugs? - briefly
«Absolute» ethanol applied undiluted to cracks, seams, and directly onto visible insects causes rapid desiccation of the bedbug exoskeleton. After exposure, wipe treated surfaces with a disposable cloth and repeat the application as needed to ensure complete eradication.
How to use absolute for bedbugs? - in detail
Applying pure ethanol to a bed‑bug infestation requires a systematic approach. The liquid must be 95 % or higher concentration to ensure rapid desiccation of the insects. Follow these steps:
- Prepare a spray bottle with a fine‑mist nozzle; fill it with the ethanol, avoiding dilution with water.
- Test a small, hidden area of the mattress or furniture for colorfastness; allow the surface to dry before proceeding.
- Direct the spray at visible bed‑bugs, their eggs, and crevices where they hide, maintaining a distance of 15–20 cm to achieve an even coat.
- Re‑spray after 24 hours if activity persists, because eggs may require a second exposure to be eliminated.
- Allow treated surfaces to air‑dry completely; ethanol evaporates within minutes, leaving no residue.
Safety considerations are essential. Wear nitrile gloves and eye protection, work in a well‑ventilated room, and keep the chemical away from open flames or sparks. Store any remaining ethanol in a sealed container, labeled clearly, and out of reach of children and pets.
For larger infestations, combine ethanol treatment with mechanical methods such as vacuuming and heat exposure. Vacuum all seams, folds, and baseboards before spraying; dispose of the bag or contents in a sealed plastic container. Heat treatment—raising ambient temperature to 50 °C for several hours—supplements the desiccating effect of the alcohol.
Monitoring after treatment involves inspecting the area nightly for live insects or new hatchlings. Continue observations for at least two weeks, re‑applying ethanol as needed until no activity is detected. This protocol maximizes the insecticidal properties of high‑purity ethanol while minimizing damage to furnishings and reducing health risks.
