Quite a few people woke up in Duluth this morning with planes buzzing over head, only 50 or so feet above tree tops.  In fact as I'm typing this, I can hear them make another pass.  Don't be alarmed, its Gypsy Moth spraying.

Treatments for gypsy moth in Minnesota can have two different goals. An eradication treatment, in the pre-infested area, is designed to completely eliminate a population of gypsy moths. An STS treatment, in the slow the spread area, is designed to reduce the gypsy moth population by two-thirds.

To reach these goals, several products are available to program managers to target gypsy moths. Most commonly, Btk and mating disruption are useful for most projects.

 

More information and the target areas can be found here at the Minnesota Department of Agriculture website.
