Control Methods |
Biological Control: Introduce natural predators like birds, parasitoid wasps, and beneficial insects (e.g., ladybugs, praying mantises) that feed on caterpillars. Handpicking: Physically remove caterpillars from plants and manually destroy them. This method is practical for smaller infestations. Bacillus thuringiensis (Bt): Use Bt-based insecticides, which are natural bacteria that specifically target and kill caterpillars while being safe for other organisms. Botanical Insecticides: Some botanical insecticides derived from plants (e.g., neem oil, pyrethrins) can be effective against caterpillars. Insecticidal Soaps: Use insecticidal soaps to control soft-bodied caterpillars by disrupting their cell membranes. Physical Barriers: Use row covers or netting to prevent adult butterflies from laying eggs on plants, reducing caterpillar infestations. |
