Kermes Scale ? #270823

Asked August 17, 2015, 2:21 PM EDT

We have a bad case of Kermes Scale in our oak tree in our front yard. What is the best treatment option?
I've had three tree companies come over and they all have different approaches to treating it...some now and some waiting till Fall, with injections in the tree line and dormant oil later.

Kermes scale control is most effectively applied in either the fall crawler stage or during winter as noted in this Planttalk article: http://www.ext.colostate.edu/ptlk/1400-11.html.
