Emerald Ash Borer

  The Emerald ash borer (Agrilus planipennis), an invasive, wood-boring beetle that attacks ash trees, was positively identified for the first time in Wisconsin in August 2008.  If you aren’t fimilar with these nasty little bugs, you may want to take a minute to look through these details to make sure you don’t have a run in. 

Characteristics of an Adult Emerald ash Borer:

  • Emerald ash borer adults are very small, metallic green beetles. Only 3/8 – 1/2 inch long and 1/16 inch wide (about the size of a cooked grain of rice).
  • Adult emerald ash borers emerge from beneath the bark of ash trees late May through mid-July, creating a D-shaped exit hole as they chew their way out of the tree.
  • Adult beetles are most active during warm and sunny days.
  • They never wander far from where they exit a tree (less than one mile) in search of a mate. Once they find a mate, the female will lay 60 – 90 eggs, one at a time, in the crevices of ash tree bark.
  •  The adult beetles will feed lightly on ash tree leaves, but do not cause much harm by doing so.
  • The adult beetles live a total of three to six weeks.

Avoid Japanese Beetle Traps!

No beetle traps

University research indicates that using Japanese beetle traps can actually make problems worse. The traps are intended to trap and kill the beetles in your yard. However, they use pheromones to attract the beetles to the traps. And these pheromones bring more beetles into your yard than the traps can catch.
