How to dilute ammonia solution for fighting bedbugs? - briefly
Combine one part of 5‑10 % household ammonia with nine parts water (≈0.5‑1 % final concentration) and spray onto infested surfaces, using protective gloves and adequate ventilation.
How to dilute ammonia solution for fighting bedbugs? - in detail
Ammonia, when properly diluted, can act as a contact agent against Cimex lectularius. The compound penetrates the exoskeleton, disrupting cellular respiration and leading to rapid mortality.
Safety measures are mandatory. Use protective gloves, goggles, and a respirator rated for alkaline vapors. Perform all steps in a well‑ventilated area or under an exhaust fan. Keep children, pets, and food items out of the treatment zone.
Required items include:
- Household ammonia (5–10 % w/v)
- Distilled or deionized water
- Measuring container with milliliter markings
- Stirring rod or disposable spoon
- Spray bottle made of compatible plastic (e.g., HDPE)
The dilution ratio determines efficacy and safety. A commonly recommended concentration for bed‑bug control is 0.5 % ammonia by volume. To achieve this from a 5 % solution, mix one part ammonia with nine parts water (1 : 9). For a 10 % source, use one part ammonia to nineteen parts water (1 : 19). Adjust volumes proportionally for larger batches.
Mixing procedure:
- Measure the required volume of ammonia using the calibrated container.
- Add the measured ammonia to the empty spray bottle.
- Slowly pour the calculated amount of water into the bottle, allowing the mixture to cool if heat is generated.
- Secure the bottle cap and invert several times to ensure homogeneity.
Application guidelines:
- Apply the solution directly to infested areas: mattress seams, box‑spring joints, bed‑frame crevices, and baseboard cracks.
- Saturate surfaces without excessive runoff; a fine mist is sufficient for contact.
- Repeat treatment after 48 hours to target newly hatched nymphs.
After each use, empty the remaining solution, rinse the spray bottle with water, and store it out of reach. Conduct a spot test on fabrics to verify colorfastness before full application. Dispose of any unused mixture according to local hazardous‑waste regulations.
