|My cherry tree has many websacks. Worms are getting out of the sack and they are all over my deck. I'm allergic to insecticides. What should I use to get rid of all those worms?

|If you can find someone to spray the tree, you can control the caterpillars with the botanical Bt (bacillus thuringensis). It will control the caterpillars but won't harm beneficial insects. If you cannot spray at all, the best approach is to pull the webs out of the trees and squish the caterpillars one by one.
