How should kerosene be diluted with water to fight fleas? - briefly
Mix one part kerosene with at least four parts water, stir until a uniform emulsion forms, and apply only to areas inaccessible to pets. Use protective gloves, work in a well‑ventilated space, and keep the mixture away from open flames.
How should kerosene be diluted with water to fight fleas? - in detail
Kerosene can be used as a flea‑killing agent only when it is emulsified with water in a precise ratio; otherwise the mixture separates, creates hazardous vapors, and fails to contact the insects effectively.
A reliable formulation consists of one part kerosene to nine parts water (1 % v/v). Add a non‑ionic surfactant—such as a few drops of liquid dish soap per litre of mixture—to stabilize the emulsion. Stir vigorously for at least one minute, then allow the solution to rest for five minutes before use. The surfactant reduces surface tension, enabling the oil droplets to remain suspended and to coat the flea‑infested surfaces.
Application steps:
- Wear protective gloves and goggles; work in a well‑ventilated area.
- Transfer the measured water into a clean bucket.
- Introduce the kerosene, then the surfactant.
- Mix with a sturdy stick or mechanical agitator until a milky appearance is achieved.
- Pour the emulsion into a spray bottle equipped with a fine‑mist nozzle.
- Saturate carpets, upholstery, pet bedding, and cracks where fleas hide. Ensure the material remains damp for at least 30 minutes.
- After the exposure period, vacuum thoroughly and wash washable items with hot water and detergent.
- Dispose of any unused solution in accordance with local hazardous‑waste regulations; do not pour it down drains.
Safety considerations:
- Do not exceed the 1 % concentration; higher ratios increase fire risk and can damage fabrics.
- Keep the mixture away from open flames, sparks, and hot surfaces.
- Test a small, inconspicuous area for discoloration before full application.
- Store kerosene in a sealed container separate from the diluted solution.
Effectiveness hinges on proper emulsification, sufficient coverage, and adequate contact time. Failure to incorporate a surfactant or to maintain the recommended dilution will result in rapid separation of oil and water, leaving fleas unharmed and exposing occupants to unnecessary chemical hazards.
