Preventing IPS Beetle Infestation
The IPS Beetle is a common pest of pine and spruce trees in the Denver, CO area, and highly dangerous to trees - it is one of the few pests that will kill it. Once a tree is attacked by IPS Beetles, the tree must be removed, as there is no cure.
Practices to Prevent Infestation
Like most bark beetles, IPS Beetles attack trees that are stressed due to drought or root damage. Thus, the key to preventing this insect from attacking your trees is to follow sound cultural practices
that promote healthy trees. Donovan Arborists recommends staying consistent with deep root watering
and dead limb pruning
to keep your trees vigorous and strong.
Spraying for Year-Long Protection
Adult IPS Beetles are active from March through September and have many generations per season. Two sprays are required to provide year-long protection. Donovan Arborists can also apply the material directly into the tree for clients who want to protect their trees but do not want chemicals sprayed on their property. This method of application lasts for 2 years.
