The vac is so powerful when they hit the inside of the tank they LITTERLY (pun intended) come apart. I did online research, yellow jackets do not pollinate much and are very aggressive, mean bees. I have honeybee nests and bumblebee nests around here but those I will not touch those nests because those bees pollinate crops.
Yellow jackets are the scum of the bee world, they actually kill other types.
