There are a number of insects that can cause damage to trees in the spring. The one that has received a lot of attention lately is Mountain Pine Beetle, which attacks a variety of pine trees. Others insects that warrant mention are Ips Beetles (another bark beetle that attack spruce and pines), White Pine Weevil (which kills the top leader of spruce trees), Poplar Borer (which causes tunneling and eventual death to aspen trees), and Lilac Ash Borer (affecting ash trees). The best way to truly protect your trees is with a preventative spray so your trees will not be attacked in the first place. This needs to be applied in the spring before the insects become active.
Not all bugs are bad however, and every tree doesnâ€™t necessarily need to be treated. Ask Prima to evaluate your trees and discuss the best treatment options
