Useful Yellow Jacket Information:

  Only the fertilized female yellow jacket over winters.
  All males die during the winter...This may be the reason they are so aggressive in the early fall because they know this is their last “Hoorah”.
  When fertilized females emerge from hibernation in early spring, she needs protein to nurse her young offspring. To start with she is a single mom doing it all until she can raise some workers.
  Traps placed and maintained in the early spring will help to severely reduce the yellow jacket population in the fall.
  For every female you capture in the early spring, that will eliminate a yellow jacket nest of 500 to 5,000.
