Protect Your Ash Trees in Dane County from Emerald Ash Borer (EAB)

The Emerald Ash Borer (EAB) is now a confirmed threat to ash trees in Dane County, Wisconsin. Don’t let this invasive insect destroy your valuable trees! Keyman Lawn, Tree and Pest offers a highly effective treatment guaranteed to protect your ash trees for two years with a single application.

Our Proven EAB Treatment

We utilize the Arborjet trunk injection system to deliver TREE-äge™ directly into your ash tree’s vascular system at the base of the trunk. This method ensures the product is carried throughout the tree, providing comprehensive protection while eliminating any risk of chemical exposure to people, pets, and other wildlife in your Dane County landscape. Treatments can begin as early as May.

Prevention is Key, but Treatment is Possible

The best defense against EAB is prevention. We strongly recommend treatment before an infestation occurs. However, if your ash tree is already infested, it may still be salvageable. Ash trees can often withstand up to 30% damage before removal becomes necessary. The cost of removing a large, mature ash tree is significantly higher than a single TREE-äge™ treatment. Our certified Arborist can assess your tree’s condition and determine if treatment is a viable option.

Scientific Evidence of TREE-äge™ Effectiveness

Extensive studies conducted by researchers at MSU and OSU have demonstrated the exceptional effectiveness of TREE-äge™ (the product we use) in controlling EAB. A single injection in late spring or early summer, after the tree has leafed out, provided excellent control for at least two years, even in areas with high EAB populations.

As reported on www.emeraldashborer.info, these studies showed that untreated trees had hundreds of EAB larvae, while trees treated with TREE-äge™ experienced a 99% reduction in larvae. Even two years after treatment, virtually no larvae were found in the treated trees, proving the long-lasting protection of TREE-äge™. Furthermore, TREE-äge™ proved more effective than other systemic neonicotinoid products in side-by-side comparisons.
