Your gonna laugh but it worked for me. I asked an old timer I worked with if he ever had a huge wasp nest he had to get rid of and he proceeded to tell me how to rid of it. 1st you find an old straw broom, dewsh it with charcoal fluid or diesel, 2nd you cover yourself up with a heavy coat, mosquito netting on your face, 3rd put on heavy leather or the heavy rubber gloves, 4the wrap a heavy scarf around your neck,5th put on a heavy coat and a cowboy hat. Next practice getting up the 8 ft ladder with the broom to the height of the nest. If you feel queezy that's how your suppose to feel, have your vehicle close enough for you to jump down and have the door open if this plan starts going south, this is what I did and it worked . I lit the broom went up the ladder stuck the broom right under the nest and all you hear is all the wasp dropping to the ground because you have burned their wings off in a millisecond.
