Emerald ash beetle quandary

Asked February 19, 2018, 3:42 PM EST

How can one effectively evaluate tree services when dealing with Emerald Ash Beetle control? We have 3 ash trees in our yard, the largest being 25 inches in diameter, the next about 14 inches in diameter, and the smallest about 10 inches in diameter. After asking for free estimates from several companies here in Longmont, we have received varied recommendations. One said cut down the largest and smallest tree, another said keep the two larger trees, and so on. In terms of treatment, some say treat every year, some say every two years, some every three. Plus pricing is all over the map, the only common element is all are expensive. How can one make an informed decision when there seems to be little commonality in the recommendations. By the way, the City of Longmont's forestry department is telling us to cut all of the trees down and buy replacement trees from them. Thanks for any help you can give. Fred Jurgemeyer

Below is a link to some control options for EAB in Colorado from our Extension program.


Also, here is a link to a Decision guide that may help in determining some next steps to help manage the EAB.
