|Merit||Arbor Jet||Six Year Cost|
The "Merit" treatment option is utilized for situations in which the insect pressure is considered low. Insect pressure refers to a collection of factors such as: concentration of EAB insects infesting affected trees, and relative proximity of these infestations to houses or other vulnerable buildings.
"Arbor Jet" is used in cases of high insect pressure: large concentrations of insects close to buildings.
The "six year cost" is simply an estimate of how much continuing treatment will cost over a six year period to help plan future treatment costs over the life of the tree.
The Emerald Ash Borer (EAB) is a highly destructive, invasive insect species of Asian origin, confirmed to be in Colorado as of September 2013. It is a borer which targets only Ash trees, and can kill trees of any size, age or health.
With an estimate that one in five urban trees are ash trees, EAB poses a real threat to our urban forests and our landscaping trees. However, the insects infest ONLY Ash trees - "Mountain Ash" trees are of a different genus and are not affected. For more information, see ArborScape's article: Can I Save My Ash Tree? Should I?
There are several preventive and curative tactics that have developed since the emerald ash borer was discovered in Michigan in 2002. Treatments options vary by tree condition. Direct injection into the bark of the target ash is one type. Another way involves soaking the soil around the ash tree with a chemical treatment.
Chemical treatments appear to work best when done before the ash tree becomes infested with EAB. The earlier you establish a treatment plan, the better the chances of an arborist being able to protect your tree. For more info, see our EAB Frequently Asked Questions article.
