What are those purple boxes hanging in the trees?
They’re pretty obvious all around the area, and all over Virginia–purple glue traps to capture emerald ash borers
which have decimated ash forests in part of the U.S. and are threatening Virginia, according to the Virginia Department of Agriculture and Consumer Services. Native to Asia, the pest was first discovered in Detroit in 2003, and a year later on nursery stock in Fairfax County. Since then, a quarantine area was established that includes the counties of Arlington, Fairfax, Fauquier, Frederick, Clarke, Loudoun and Prince William, and the cities of Alexandria, Winchester, Fairfax City, Falls Church, Manassas and Manassas Park. No ash trees, green ash lumber or ash wood products, or hardwood firewood, may be transported out of those areas. Last year, about 5,500 traps were placed around Virginia. They are baited with natural plant-oil attractant and covered with a nontoxic glue to catch the insects, which are attracted to the color purple.
