From the corner of my eye, I noticed a purple box hanging from a tree. I was past it before I could do more than turn my head. My first thought was that the kids were up to something. Then I saw another one. This time I pulled over to see what was going on.
The USDA is doing an Emerald Ash Borer Survey in 48 states. The purple boxes are really 3-dimensional plastic triangular traps. Apparently Ash Borer groove on the color purple. The traps are baited with Manuke oil. The adults fly around and if they land on the trap they will get stuck. The traps will be monitored during the Spring and Summer and removed in the Fall.
Having the traps doesn't mean we have the offending beetle, but they are looking for it. The goal is to define the boundaries of infested areas.
If you see one of the traps on the ground, call the EAB hotline at 866-322-4512 and remember don't move firewood. Burn it where you buy it.
