I just got back from a bicycle race and found 13 yellowjacket queens in my traps. Not a bad haul.
Update: As of 7:00 AM, 5/19/2008, my body count is up to 16.
Another update: As of Monday evening, 5/19/2008, the body count is 24. That's 120,000 yellowjackets that won't be buzzing my neighborhood this summer.
This is the time of year to dent your yellowjacket population. Put out your traps. Every yellowjacket you see this early in the year is a queen. And every queen you kill today reduces the yellowjacket population by 5000 come late summer. That makes my harvest, 65,000!
