There are two types of
caterpillars that we are plagued with that form large webs or tents in our
trees. They are the Eastern tent caterpillar and the fall webworm. Both cause
more aesthetic damage than permanent harm to the trees. Collect the webs when
you see them if they are reachable. Putting bands of sticky substances such as
tanglefoot around the base of the trees can catch some before they move up the
trees. Sprays of Sevin or BT can also be effective if you spray into the web and
on the surrounding foliage.
How do I get rid of
armyworms and the webs they form? This year my problem got much worse.
