Offense: Eradication Methods
There are four basic types of offensive tactics that can be taken to eradicate Yellow Jackets:
1. trap workers
2. trap queens
3. nest destruction
4. smash them one by one
Suggested Program
Begin by setting apple juice traps in March and April to capture queens.
NOTE!! Yellow Jackets seem to be in very low abundance._ However, every one you see in March is a queen._ For every queen eradicated, there will be 5000 less workers in August!_ Set traps 100 feet apart in a perimeter around the area; 5 feet above the ground.
Rebait traps every two weeks with fresh apple juice.
Continue trapping until May 15.
If you are very careful, set out some poison bait dispensers every 100 feet.
Use canned mackerel (3 ounces of bait to 1/2 teaspoon of Knoxout poison).
NOTE!! Keep poison away from children, pets and wildlife!! Traps must be suspended at least 5 feet above ground._ Use only approved, ecologically safe dispensers.These dispensers can be set fresh every 4 days through June and July.
At height of Yellow Jacket season, August through October, use apple juice traps again. Change juice every week until November.
