Question From: WASHINGTON
Q: Tiny greenish droppings fro douglas fir. During heat wave 1-2 millimeters. A few striped inch worms present/descending on spider-like thread. Almost too many of the droppings to be a pest. Tree looks healthy. Can I send a photo? Pacific Northwest. What might this be? Thanks!
A: Your best bet is to get an onsite inspection from a certified arborist. To find a professional in your area go to tcia.com and enter your zip code, Best And Happy Yardening, Nancy.
