Many of our clients have us treat their Spruce and/or Arborvitae not only to control an active Mite problem, but also as a preventative treatment, which is the best approach.
Spruce Mites cause a ‘drab’ green or actual browning of the interior needles. They will not attack the new candle growth that first appeared this year so don’t be fooled by nice exterior color on the tree. Next year, beginning in the Spring, the new candle growth from this season will be attacked by the ‘overwintering’ mites. To see a video on how to test for Mites Click Here.
Although some of our clients have these trees and shrubs treated once a year, many have them sprayed twice; once in Spring and once in the Fall. We are finding that two applications, on a Spring and Fall time table, controls Mite damage more effectively.
If we are only treating your Spruce and Arborvitae in the Spring, and you would like to be included in the Fall application schedule, just call or email the office. The Fall price will be the same as the Spring application.
Mites are difficult to control as they multiply every 10 to 17 days. The more that show up, the more damage they do. On a treatment note, we need to rotate the products that we use so that they cannot build up a tolerance and immunity to any particular product, which they famously do.
