How to Kill Insects on Chili Plants
- 1). Pick off visible insects by hand and drop them into a container filled with water and liquid soap.
- 2). Spray the foliage of chili plants with a forceful blast from the garden hose. This removes insects, larvae, and eggs. It also washes away honeydew, a substance excreted by aphids that can lead to fungal disease.
- 3). Fill a garden sprayer with insecticidal soap solution, which kills insects but doesn't affect developing peppers.
- 4). Apply the solution to the foliage of the chili plants, paying special attention to the bottoms of the leaves, where insects tend to gather.
- 5). Spread diatomaceous earth around pepper plants to kill slugs. Repeat the application after rainfall.
- 6). Contact your local extension office if an infestation persists. Snip off an affected leaf and take it to the office for diagnosis and treatment advice, as location and weather conditions sometimes play a role in a product's effectiveness.
