You can see the multitude of yellow jackets captured.
I continue to smash them with my fly swatter in front of the hives. The above is about two weeks of captures. our temperatures are in the 20's at night an in the mid 60's during the days.
Here are the girls going at it with a "robber" yellow jacket
And still they bring in pollen. Tomorrow we have snow in the forecast and a high of 46.
I think this is dandelion pollen.
