How to get rid of caterpillars on tree

Asked June 6, 2019, 12:03 PM EDT

I noticed a small tree in the midst of some maples that is infested and has been completely defoliated by caterpillars. They have web like coverings at the ends of branches where they ate the leaves, there are some caterpillars and other dark things in those and there are also long strings of web hanging down with masses of the things clinging to the end. The tree looks like scrubby like thing. It is in the midst of maples which appear to be untouched, just incidental contact. It is also located next to a large old mulch pile. How do I get rid of these and prevent spreading to my other trees? Also what to do with the mulch? is it infested? I'm in NW Canton, rural area.

Hello,

I can’t see the insects but this looks like Eastern tent caterpillar. Here are pictures, please take a look to see if this matches what you see-

If not, try taking a stick and putting some insects on a plain piece of paper and taking a picture.

If they are these caterpillars, then no, they will not infest your mulch- there is nothing for them to eat there.
