Emerald Ash Borer

(placeholder)

WHY PROTECTING YOUR ASH TREES IS SO IMPORTANT

The deadly Emerald Ash Borer (EAB) was first detected in Boulder, Colorado in 2013 and has quickly spread to the communities of Longmont, Lafayette, and Lyons.  Unfortunately EAB is a non-native pest that has no natural predators to help keep it in check.   EAB only attacks Ash trees in the genus Fraxinus (so Mountain Ash are not susceptible to EAB) Humans can unknowingly transport EAB through firewood or the moving of live Ash trees. Adult beetles tunnel under the bark of Ash trees, girdling the tree and preventing water and other nutrients from being distributed.  

By the time symptoms are first noticed, even previously healthy trees die within 2-4 years.

There are a couple of treatment options available for managing EAB through the use of insecticides which need to be applied on an annual or biannual basis to maintain control.  

We are currently encouraging all of our customers to immediately start a preventative EAB care program.

Especially those customers with High Value Ash Trees or those who reside in areas close to the infested municipalities of  

Boulder, Lafayette, Lyons, Longmont, Berthoud, and South Loveland.


In an effort to mitigate the harm befalling bees and other pollinators, we at HLS Colorado are encouraging TRUNK INJECTIONS to protect against EAB and other boring insect infestations.  Our trunk injection programs are environmentally safe as all chemicals are injected directly into the trunk of the tree, where the insecticide is taken up by the vascular system of the tree and distributed throughout.  

The effects of each treatment lasts for 2 years and also protects against infestations from Lilac Ash Borer (a common and harmful pest in Northern Colorado, which tunnels into the trunk and lower branches of trees-girdling the vasucular system and impeding nutrient flow, weakening the tree, and causing irreperable harm),

AND the Ash Bark Beetle (which contributes to limb dieback and canopy thinning).
