Yellow Jacket stings. A friend Matt was helping me when he had the unfortunate experience of stepping into a nest of Yellow Jackets and was stung 3 times on his ankle and lower leg (so he thought). I immediately grabbed a medium size magnet and slipped it into his sock. Within 5 minutes he had calmed down and realized that there was no pain and the area was not swelling. Matt kept the magnet in his sock and insisted on helping me with yard work. Later on after going home, he called and told me that he had counted 8 bites. One regular (medium size) magnet had neutralized the sting of 8 Yellow Jackets which have one of the most powerful venoms in the insect world.
