Tree Spraying Services

Tree Spraying

Personalized Tree Spraying Services for the Fort Collins Area

So, something’s “bugging” your trees, and now you need a tree spraying service.

Maybe you have a specific tree concern like aphids or borers. Or, perhaps your concerns are more general; you’re looking for someone to come by and do regular check ups on your trees, making sure there are no issues and taking care of problems as they arise.

Great, because that’s what I’m here for. I understand your tree problem: I’ve probably dealt with it before. Now, I know I’m not the only tree spray service in Fort Collins. There are at least another half dozen (licensed) companies. But let me tell you what I can do for you that they can’t:

  • Genuinely listen to your concerns, and develop a tree spraying program uniquely tailored for you and your trees.
  • Provide a higher standard of work, as I personally perform all treatments.
  • Use (OMRI Organic products) that minimize environmental impacts and keep your family safe.
  • Guarantee results.

Now, to the casual observer, a tree may appear to get sick, or die, for no apparent reason.

The reality is: There is always a reason.

As a second generation arborist, I know trees. Tree insects and diseases are my expertise, and over the years I’ve learned to recognize the early warning signs of problems.

My services are not “one size fits all”. Each property and each customer is unique, and by taking the time to identify your concerns and issues first we can develop a tree spray program that really fits your needs.

At ArboRx Tree Care it goes beyond just spraying trees; to me, the goal is to fix a problem. So looking at what is actually wrong with a tree, and determining the correct solution is a better approach than simply signing you up with a tree spray program.
In fact many of the treatments I do don’t involve sprays at all. By incorporating Integrated Pest Management practices we can reduce cost and environmental impact, while monitoring results ensures that treatments are working. Integrated Pest Management means addressing the underlying issues that are causing trees to become sick. Proper watering, mulching and fertilizing are just some of the things we can do to improve the health of your trees.

Since March, 2014 ArboRx has been a member of the EPA’s Pesticide Environmental Stewardship Program, which aims to reduce the need for pesticides.

A quick look at some of the more common tree insects:

The Usual Suspects


Look for them on Ash, Aspen, Honey Locust, Linden, Maples and many shrubs such as Spirea and Roses.

Mites are frequent pests on Honey Locust, Spruce, Pines and Juniper.

These tiny insects are highly damaging on Boxwood, Privet and Lilac. Golden Privet can sometimes be killed by thrips.

Pear slugs are common on pear and cherry trees. They are leaf “skeletonizers”.

Caterpillars are common pests on Roses, and Fall Webworms can be found on many kinds of trees in the fall.

Eco-Friendly Treatments

As an eco-friendly company, I also offer alternatives to traditional treatments. Be sure to ask about these if you’re interested, otherwise I mix traditional and alternative treatments as needed in my Inspect & Treat program. In the interest of protecting our environment and your family, I’m proud to offer the following great alternatives:

Soaps work well to control soft-bodied insects such as aphids, but cause little to no harm to people, pets and pollinators. Because hard-bodied insects are mostly unharmed, soaps don’t seriously affect insect predators such as lady bugs.

In the summer we can use light-weight (summer) oils to control common leaf insects as well. Oils work by smothering and suffocating insects, rather than by any chemical means. Oils can work better than some traditional pesticides because insects can’t become genetically resistant to oils. Although beneficial insects can be hurt by oils, their populations build up faster because oils have little to no residual activity.
Horticultural oils also help control certain plant diseases- an added benefit.

Spinosad is a natural insecticide produced by a bacteria. It works very well on thrips, caterpillars and moth larvae, while being relatively benign to most other organisms.

Pyrehtrins are naturally derived from Chrysanthemum plants and are a broad spectrum insecticide, and at lower rates acts as an insect repellant. Synthetic versions of this natural product have become very popular.

Bt is a natural product that is effective against only very specific pests, and essentially harmless to other pests, pets, pollinators and humans. However, there are few uses for Bt where Spinosad would not work better.

Cyd-X is an awesome product that controls Coddling Moths, which are the worms you find in apples. It is a virus that attacks only Coddling Moths, and is completely harmless to everything else. In fact, the label allows apples to be sprayed and harvested the same day.

Serenade is a bee-friendly treatment for Fire Blight diseases in apples, pears and other fruit trees. It is a “good” bacteria that out-competes the Fire Blight bacteria and is almost as effective as traditional fungicides and antibiotics.
