Brown oak tree droppings
We have lots of small brown balls dropping from our oak trees which I think are waste from caterpillars in the trees. They turn green & slippery when wet & hard to remove when dry and firmly attached to our deck & outside furniture. Lots on the bottom of shoes when walking under the trees. How long will these last & is there anything we should do to control them? I don’t remember them being this bad before in Hubbard Lake!

So there’s nothing we should do to control them? Will they destroy the trees - they’ve already eaten a lot of leaves.
