While the EAB has been found in trees as close as Boulder, CO, there is still no confirmation of an EAB infestation in Wyoming. At this time, the WSFD does not recommend insecticide treatments or tree removals in anticipation of its arrival.
The EAB is an exotic insect native to eastern Russia, China, Japan, and Korea that was first found in the US in 2002. It is likely that EAB was inadvertently transported to the US in packing crates made of ash wood. EAB can kill any species of ash by chewing on the inner bark, but is especially damaging to Green Ash populations.
They are quite pretty but don't let that fool you! These little bugs have already killed millions of ash trees across the country. Green Ash is one of the four most common trees in towns and parks in Wyoming, and accounts for 20-40% of community trees state wide. An EAB infestation would deal a tremendous blow to Wyoming towns and cities!
The most likely way that EAB could move into Wyoming is through the transport of firewood, raw ash logs, and nursery stock.
If you think you may have an EAB infestation in your trees, or notice signs of boring or other damage, contact the Wyoming State Forestry Division at 307-777-5495.
