Well, they are “hangry.” (No, really. They are).

According to the Montgomery County Beekeepers Association, most yellow jacket colonies grow the largest during late summer and early fall, just when their food sources begin to diminish. Just like humans, when they are not eating and are hungry, they get frustrated and aggressive.

During the spring, there are fewer yellow jackets, and that allows food for the bugs to be plentiful.

Yellowjackets are not only aggressive to humans, but they are known to target massive honeybee hives for food, eating the bees and their larvae.

Not only are the yellowjackets annoying, but their sting packs a punch. All yellowjackets can sting multiple times. This is because yellow jackets lack a barb on their stinger. Bees have this barb, which causes the stinger to be struck in the skin of a human. Yellowjackets can sting numerous times, all the while injecting the victim with venom.

If you are stung, WebMD suggests the following:

  • Remove the stinger. As mentioned before, most of the time, these bugs don’t leave a stinger. But sometimes they do break off. Use a fingernail or credit card and gently remove it if it is embedded.
  • Wash the area thoroughly with soap and water.
  • Use a cold pack
  • Pain medicine, as well as a 1% hydrocortisone cream, may reduce the pain of the sting

The good news is by the middle and end of fall, all yellow jackets die off and will be gone until the following spring.
