How do you kill webbing caterpillars?

The easiest way is simply to leave them alone until they fall to the ground. Then treat the soil with a Neem oil drench to eliminate the pupa and improve the quality of your soil. You can also treat them as you would any pest caterpillar with biological control by applying Bacillus thuringiensis (Bt) early on.

How do you get rid of spinning web caterpillars?

Simply wrap a baggy around your hand and pull the silken nest off of the branch. Then tie and dispose of the baggy. Alternatively, an insecticide such as Bifenthrin may be applied to foliage and twigs to help control the caterpillars. Both treatments are most successful when applied on the youngest larvae.
