I used 1 cup of gasoline after dark late last August on a yellow jacket nest & they were eliminated overnight. This nest was very hard to find & took 3 weeks to locate. I was bitten severly each week for 3 weeks & finally got severe leg swelling from it.
The nest was in a hole hidden at one corner of a pile of walnut tree trunk logs. These wasps enter & leave the hole at extreme speeds, only one at a time & nearly vertical, making them very hard to see & very hard to locate. They will attack & bite you if you are standing near the nest blocking their flight. So, if you sense very quick "bugs" persitently flying around you or getting on you, you may be near a nest & need to move away quickly. They are fast. I have learned to take cover in bushes in the woods - for some reason they won't fly after you if you're in bushes & they don't seem to make ground hole nest in bushes. They will also make nests in tree & bush branches & in doorways. Brown wasps are relatively friendly compared to these yellow & black killers.
I used baking soda on the bites after the 3rd attack (it should be put on right away to avert pain & swelling, which can be severe to deadly). It is also important to drink baking soda water (1t or 1T/glass of water) to neuralize the sting acid & your own fear-fright acids. And I used red bush tea since it is for hydration & I was also very dehydrated. But the redbush tea unexpectedly also got rid of the leg swelling.
These wasps will both bite and sting repeatedly. One attack can quickly kill a allergic person by the poison, but the swelling that occurs later on can also kill if left to itself. Attack by multiple yellow jackets is definitely deadly. Since I had trouble finding them, I was bitten 4-6x for 3 seperate attacks, on neck, legs & ankles, one each week of August - about 15 bites-stings. My big mistake was not applying baking soda-water paste to the bites at all 'til it became obviously very serious after the 3rd attack.
This also works on black ant hills. I have done 12 small hills & the results are fast & complete. Only used one cup of gasoline per hill.
No damage to grass or to soil or to plants occurred.
