  • How to Help Prevent Mountain Pine Beetle Infestation

    Remove and treat infested trees. 

    Remove dwarf mistletoe from your trees.

    Dwarf mistletoe weakens trees, making them more susceptible to mountain pine beetle attack. Contact a professional tree service if you need help.

    Thin your forest to keep it healthy.

    This allows your trees to grow stronger because they don’t have to compete as much for resources.

    To develop a forest management plan for your property, contact the Colorado State Forest Service, Golden District, View exit disclaimer policy page for links to third-party websites. 303-279-9757. You can also contact a professional forester.

    Treat high-value trees to prevent infestation.

    Using Carbaryl (Sevin) or permethrin (Astro)-based pesticides on a yearly basis can help prevent infestation of individual trees (May 1 through July 15).

    Always read and follow label directions. If you prefer not to do the work yourself, contact a licensed pest-control professional.
