Recently I have noticed my evergreen shrubs are heavily covered with patches of some type of webs. It does not appear to be spiders but I cannot see anything specific that is creating them. I recently trimmed the hedges and with a few days the webs were back. It has been extremely hot and humid here in southeastern Illinois for the past two weeks.
Can anyone tell me what I am dealing with here and how I can rid my hedges of whatever pest has invaded them.
