Most effective bug killers use a combination of pyrethroids, neem oil, and botanical extracts. Pyrethroids mimic natural insecticides found in chrysanthemum flowers, while neem oil disrupts insect hormones.
Application Methods
Spray, granular, or foliar. Sprays offer quick coverage; granules are slower but longer lasting. Foliar sprays target airborne bugs.
Safety and Environmental Impact
Look for products with low mammalian toxicity, minimal runoff, and biodegradability. Eco-friendly options are often labeled “non‑toxic” or “pet‑safe.”
