Common conclusions

The insects on your chilly peppers are aphids. You can control them by washing them off the plant with water spray. Insecticidal soap should be used with severe infestations.

The insects on your chilly peppers are beet armyworms. Handpick or spray actively feeding caterpillars with BTK (Bacillus thuringiensis) in the evening.

The insects on your chilly peppers are flea beetles. Prevent problems by covering young plants with row cover. Control severe infestations by spraying or dusting plants with pyrethrin.

The insects on your chilly peppers are leafminers. Prune off and destroy all infested leaves. Cover plants with row cover until flowers open to prevent adults from laying eggs on plants.

The insects on your chilly peppers are leafrollers. If the infestation isn't severe, handpick the rolled leaves with caterpillars. Spray more heavily infested trees with light horticultural oil according to the directions of the label to smother the insects and any eggs.

The insects on your chilly peppers are pepper weevils. To control them, spread a drop cloth around your plant and shake it so the adults drop. You can get rid of them after that. Spray leaves several times with pyrethrin for major infestations.

The insects on your chilly peppers are thrips. Several species attack chilly peppers. Control thrips by introducing lady beetles or lacewings, their natural predators. Insecticidal soap helps in severe infestations.

Corn earworms often attack chilly peppers and cause the fruit to color prematurely. Small holes and sawdust-like material can be visible near stems. Once caterpillars are feeding in fruit, it is too late to control them by spraying. Pick and use or destroy infested fruit. Spray BTK it caterpillars haven't entered inside the fruit.
