How should I dilute intavir for bed bugs? - briefly
Intavir should be diluted to a 0.1 % solution (approximately 1 ml of product per liter of water) for bed‑bug treatment. Apply the mixture with a spray bottle, thoroughly covering seams, cracks, and other infested surfaces.
How should I dilute intavir for bed bugs? - in detail
Intavir, a pyrethroid‑based concentrate, must be mixed with water to achieve an effective concentration against Cimex lectularius. The recommended dilution ratio is 0.5 ml of product per liter of lukewarm water, producing approximately 0.05 % active ingredient. This concentration provides sufficient knock‑down while minimizing residue on fabrics.
The preparation process should follow these steps:
- Measure 0.5 ml of intavir with a calibrated syringe or dropper.
- Add the measured concentrate to a clean container holding 1 L of water at 20–25 °C.
- Stir the solution gently for 30 seconds to ensure uniform distribution.
- Allow the mixture to stand for 2 minutes before use; this period permits the surfactants to activate.
Safety precautions are essential. Wear disposable gloves, protective eyewear, and a mask to avoid inhalation of aerosols. Conduct the mixing in a well‑ventilated area, away from open flames or sparks, as the formulation is flammable.
Application guidelines:
- Apply the diluted solution directly to bed‑bug harborages—mattress seams, box‑spring crevices, headboards, and furniture joints—using a spray bottle calibrated to deliver 0.1 ml per cm².
- Saturate infested zones without overspraying onto non‑target surfaces such as skin, eyes, or food preparation areas.
- After treatment, keep the area closed for at least 4 hours to allow the product to act and dry.
Re‑treatment should occur after 7 days, targeting any newly emerged insects. A second application after 14 days helps to eradicate residual populations. Dispose of any unused solution in accordance with local hazardous‑waste regulations; do not pour down drains.
Record the date, dilution ratio, and locations treated for future reference and compliance with integrated pest‑management protocols.
