Summit Biological Caterpillar and Webworm Control RTS is an all-natural herbicide that controls webworms and caterpillars. Contains an active ingredient which effectively targets and kills these pests but does not harm beneficial insects, birds, or earthworms. It is an excellent alternative to chemical insecticides because it provides the same effect using organic ingredients. It is safe to apply on fruits, vegetables, and other edible plants since it is OMRI listed and it is approved for organic gardening. Kills caterpillars and webworms when they ingest treated foliage by inhibiting feeding until pests die of starvation. It controls leaf-feeding caterpillars like cabbage loppers, bagworms, gypsy moths, fall webworms, and tent caterpillars. Best applied when caterpillars and worms are first noticed. Reapply after heavy rain. Repeat application at five to seven-day intervals as needed.

Summit Biological Caterpillar and Webworm Control is not labeled for turf application. Dylox would be great for a quick kill.

For best results, Summit Biological Caterpillar and Webworm Control should be applied when sod webworms are small and they must be actively feeding on treated, exposed foliage.
We would suggest contacting your local cooperative extension office for the best time to treat for sod webworms in your area. Adult cutworms lay their eggs in the spring and larvae emerge and begin feeding as early as June with damage appearing in June/July.
You can use a Bt product such as Summit Biological Caterpillar and Webworm Control if you are finding caterpillars on the plants. If there are an adult stage insect such as scale or mealybugs, then this would not control those insects.
