    Hello,
    I have noticed the inner branches of my Douglas fir is covered by a layer of webbing, with little whitish spots embedded inside. Am I looking at an impending caterpillar infestation and is this something that should be treated? If so, what are some suggestions?

    My phone camera doesn't mangify very well, so the pictures are somewhat blurry.

    Thanks in advance.

    Maybe give it a good soaking with a high pressure hose.
