The invasive beetle, Emerald Ash Borer has killed Millions of Ash Trees in Michigan and has radiated outward from its point of origin near Detroit. The beetles are mostly transported by human activity moving firewood or other wood products and nursery stock infested with the beetles. Emerald Ash Borer populations are rapidly expanding across Indiana and the number of dead and dying trees is exploding.
Emerald Ash Borer
In Indianapolis, Indiana beetle-killed ash trees were
blown down by high winds. This has forced the city to take down nearby dead and dying ash trees to protect public property and safety. Cutting down trees is expensive, but it must be done to protect power lines and public safety. Entomologists are making slow advances in controlling the pests. Homeowners can treat trees with systemic insecticides to protect against the borer. However, treatment is expensive and must be repeated. Eventually, the ash trees will be replaced. Treatment of all the ash trees in the vast parks and wooded areas, would be too expensive. Those will soon perish.

Sadly, I’ve seen what look to be emerald ash borers on our property in Connecticut. I’ll work with our extension agent to eliminate them from our woods, but my immediate question is, do they bite humans?
That is what I want to know do they bite humans? I have bites and I think they are from them because I was sitting by wood pile and it was ash!
They don’t bite people. Mosquitoes or another biting fly are more likely.
