Answer 1

The webworm, Hyphantria cunea (Drury), is a common pest of trees. It attacks more than 88 different kinds of plants, including many fruit, nut and ornamental trees and shrubs. It does not attack conifers (pines and other needle-bearing trees).

Control

Webworms can often be controlled without insecticides by removing and destroying any leaves that contain egg masses. Larvae may be knocked out of low-hanging webs, with a stick or broom, and into a box or garbage bag for disposal. Or, webs can be pruned from smaller branches. Many beneficial insects attack the egg and larval stages of fall webworm. You can help these predators and parasites get to their fall webworm prey by tearing open the webs. If webs are too numerous or too high in a tree to deal with individually, insecticides can be used to prevent damage. Hose-end sprayers or commercial high-pressure sprayers are best for reaching upper portions of tall trees. Because webworm larvae remain inside their webbing, insecticide sprays must penetrate the web to be effective. For best control, apply insecticides after eggs hatch and before larvae develop dense webs. Permethrin is a good insecticide to use in that is less toxic that most insecticides, gives a quick knockdown and a residual long enough to provide control for the season. This means a residual against eggs laid by moths from your neighbors untreated trees. The pesticide user is always responsible for the effects of pesticides on his or her own property, as well as problems caused by drift to other properties. Not all insecticides are registered for fall webworm on all sites and commodities. It is up to the user to read the label to make sure the insecticide is cleared for the site and commodity. Always read and follow carefully the instructions on the pesticide label.

Answer 2

Most of these worms live in bags and are active at night. I used to use a propane torch to go and burn the nests but...didnt want to damage the tree and found out that some birds like the grosbeak and Baltimore oriole will eat these worms. So now I go out in the morning when the nest will be most full, rip open the nests with a stick, kill a bunch of the worms and leave some for the birds. The worms are most vulnerable while in the nest and nothing that I know of can penetrate the nest in the way of a spray or poison. Just rip the nests open and leave the worms exposed. Take out a few hundred yourself. The early morning activity of the worms being destroyed will attract any natural predators as well. Everything is looking for food in the early morning.

Norton antivirus, it kills worms + trojans.

My friend had some trojans in his back garden and within a day Norton killed them
