oak tree mystery blob
A few days ago I noticed what looked like animal droppings. After noticing a lot more after the storm O looked up and noticed my two oak trees had these brown/black blob things on the braches. Today I went to Pahl's and brought one in and thought maybe caterpillars but they had no idea. I also cleaned up a target bag full from the yard. The trees seem to be in good condition. Hoping you can help diagnose and treat. I attached photos. Thank you!
Thank you for the quick response. One thing I question is that I’m not seeing any wasp around? Would they leave after hatching?
I would be open to having someone stop out to help me figure out a treatment
