What is the name of the plant used for fleas in the home? - in detail
The plant most frequently recommended for indoor flea control is neem (Azadirachta indica). Its leaves, oil, and powdered bark contain azadirachtin, a compound that interferes with flea development and feeding. Users dilute neem oil in water (typically 1 %–2 % concentration) and spray the solution on carpets, pet bedding, and floor surfaces. The preparation remains effective for several weeks, after which re‑application is advised.
Other botanicals with documented flea‑repellent properties include:
- Lavender (Lavandula angustifolia): essential oil applied to cotton balls or diluted in spray form emits a scent that deters adult fleas.
- Catnip (Nepeta cataria): contains nepetalactone, which repels fleas; dried leaves can be placed in pet habitats or brewed into a mild spray.
- Rosemary (Rosmarinus officinalis): oil or infused water works as a topical deterrent when applied to pet coats or household fabrics.
- Pennyroyal (Mentha pulegium): oil possesses strong insecticidal activity; however, it is toxic in high doses and should be used sparingly, strictly following dilution guidelines.
When employing any plant‑based remedy, observe the following safety measures:
- Test a small area for discoloration before widespread application.
- Keep concentrations below recommended limits to avoid skin irritation in pets and humans.
- Store oils and extracts in sealed containers away from direct sunlight to preserve potency.
Combining neem treatment with regular vacuuming, washing of pet linens, and environmental hygiene maximizes flea eradication and reduces the likelihood of re‑infestation.
