Help! the webworms are eating everything!
I am having a huge problem with webworms. They are in my neighbors' trees and are falling into my yard. They seem to have a great appetite for my purple hyacinth bean vine, persian lilac (there were at least a 100 on this shrub this morning) and my roses. I would prefer not to have to spray any harmful chemicals. Is there anything I can spray that would make these plants less tasty? For example, garlic oil/pepper ect? If I use BT on the plants do I need to spray it again after it rains? Any help would be appreciated!
