Spider Mites

There are both damaging and beneficial mites in the landscape here in Massachusetts. One of the most damaging mites of conifers is the Spruce Spider Mite. You can check for these by shaking a branch from your Spruce, Arborvitae, Fir, Hemlock or Pine over a sheet of paper during the summer.  If you see the tiny red dots you should contact Bug Busters Inc. at 781 320-9800.  There are target treatments that won’t harm the beneficial mites.

Note – most mite species target drought stressed trees
