As it turns out, my mom had a Yellow Jacket nest prolly 4 times as big as mine. It's been dry and it seems everyone up here is having issues with these ground dwelling beasts. I tried everything I did on mine, which worked on mine, but it did not phase hers. I think the hole where her nest was, was way bigger and impossible to flood with water and bubbles. I think that's why it did not work, it had much better drainage. So I decided to buy powder poison like I seen on youtube. The wasps are supposed to drag the powder into their nest and die. I read some reports though that it did not work. hmm, while at the store, I see the home bug bombs. Now that might work, just shoot one of and let it fill "their house". Well, it worked like a charm. Good deal. No gasoline, no blowing up moms house. And since the cans came in a three pack, I'm ready for two more nests! lol
