Q&A - Webworms On Birch Trees
Question:
Webworms love to eat my birch trees. They are not on any list of affected trees that I can find. I do all I can to control them with imidacloprid. Why do webworms keep coming back to an unpopular tree species? Do the worms or moths leave a pheromone that attracts them to a previous food source? They don't go after anything else that I have growing.
