About Timberline Tree Spraying & Fertilizing

Founded in 2003 at the beginning of the most recent mountain pine beetle epidemic, Timberline Tree Spraying & Fertilizing specializes in protecting your most valuable trees from the mountain pine beetle and other bark-boring insects.

Licensed in Colorado, Montana, Wyoming, Utah, Idaho, and South Dakota our proprietary sprays and spraying equipment set the standard by which other companies are judged. Today, we are committed to becoming the region's largest bark beetle protection company.

We understand the epidemic, the beetles and the issues that follow an outbreak. And we can help you fight the beetles, no matter how many – or how few – trees you have on your property. Through our systematic and professional approach to forest maintenance, your trees will stay healthy and better able to resist threats from harmful insects and fire.

We have the equipment and crews necessary to spray up to 4,000 trees per day, giving us the ability to spray entire subdivisions, golf courses, ranches or large parcels of land in a timely manner that will not disrupt your lifestyle. And with our environmentally friendly sprays, we have achieved over a 95% success rate of preventing beetle attacks.

Of course, the best method of preventing infestation is through a combination of preventative spraying and deep root fertilization. Not only will it save your trees, it will also save you time and money, as eradication costs can be ten times more expensive than preventative costs alone would have been.

Tree Spraying Experts:

  • Timberline has been saving trees for eight years during Colorado's largest and worst bark beetle epidemic in history.
  • We have adapted to the evolution of these pests, modifying our spraying equipment to reach higher up the trees and keep our chemicals better agitated.
  • We have worked alongside the Colorado State Forest Service, testing our processes along with the performance and environmental safety of the major chemicals used to combat these target pests.
  • We are thorough in our work; we have a detailed procedure and check list that each crew uses to ensure that each tree has been sprayed properly BEFORE leaving the property.
  • Due to our intense testing, research, training, and thorough tree spraying, we have achieved over a 95% success rate in and around Grand County, Colorado, the hardest hit area of the epidemic.
