Keep your trees beetle free; Bark Beetle threat in Colorado Springs

City Forestry says Ips Beetle populations in the Pikes Peak region are at elevated levels, due to prolonged drought stress in trees. They're reminding tree owners to maintain their trees and watch for signs of beetle infestation.

Ips is a common group of bark beetles that infest and damage pine and spruce trees. They develop under the bark and produce girdling tunnels that can kill trees. These bark beetles rarely attack healthy trees, and are cause most problems in newly transplanted trees or trees under severe stress.

This insect can have several generations per year starting in early spring through November. City officials say some symptoms of Ips Beetle infestation include pine trees that begin to fade, dead tops on your Spruce trees or a tree that is losing it's needles.

City Forestry offers the following maintenance tips to prevent beetle infestation:

· Do not stack freshly cut branches or firewood next to healthy pine and spruce trees (this is a breeding site for the Ips beetle);

· Keep your evergreen trees as healthy as possible and remove heavily infested trees;

· Consider preventative spraying of trees and supplemental watering ;

· Contact a tree care professional for a consultation.

Please contact City Forestry at 385-5942 for more information.
