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:

  1. Measure the required volume of ammonia using the calibrated container.
  2. Add the measured ammonia to the empty spray bottle.
  3. Slowly pour the calculated amount of water into the bottle, allowing the mixture to cool if heat is generated.
  4. 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.
