Now that emerald ash borer has been confirmed in Edina, it is important to watch for signs of trouble, including canopy dieback that begins in the top one-third of the canopy and the distinctive D-shaped exit holes in the outer bark of branches and the trunk left by adult beetles. The real problem is the larvae that bore through the bark and feed inside the tree.
In the event of an emerald ash borer infestation, Adam’s Pest Control can inject an EPA-approved, systemic insecticide directly into the trunk of healthy ash trees. A single trunk injection provides up to two years of protection against infestations. And at approximately $100 per tree, twice per year, it’s a cost-effective way to combat this threat.
Unfortunately, research indicates that if a tree has lost more than 50 percent of its canopy, it is probably too late to save the tree. For more information or to schedule a consultation, visit Adam's Pest Control online.
