Here a YouTube video of the Dawn approach:Use a bit of old window screen to cover the hole at night (for your safety). Then get half a bottle of dawn and your water hose. Pour in the Dawn and fill it up further with water.
Then put a heavy stone on the screen and hole.
In the morning take the stone off. If no yellow jacket is visible thru the screen, you're done.
I do something similar, just gas, but also light it on fire.I use a little 2-cycle oil/gasoline mix. Nothing special, just what the weed whacker uses.
I dump about a cup down the hole. The gasoline evaporates. The oil coats them & they can't breathe.
I'm sure there are more environmentally friendly options out there...
Next time, do it at night. Then all of them are in, and they will go less crazy if at all.I just put carefully the screendoor on top. They went nuts! The lady just ordered a bee suit. Will arrive Thursday, will wait till then.
Last year at the front yard we did it after dark. I was not planning to burn anything. We do not have a well.Next time, do it at night. Then all of them are in, and they will go less crazy if at all.
Also, gasoline, and especially oil (even if a little) will pollute your ground water (also when setting it on fire as not all will burn before it has seeped into the soil).
Using dawn (or equivalent) is less polluting and achieves the same results.
Do you have a well (water)...?
But some in the neighborhood might. This is not better living through chemistry. I like the old screen door idea if they can not get out. What would happen if it was just left there for a week or two? And I like the dish soap solution if you just want to be done with it.We do not have a well.
I was suggested to use a mix of Thieves oil with Borax. None of us in the area have wells.But some in the neighborhood might. This is not better living through chemistry. I like the old screen door idea if they can not get out. What would happen if it was just left there for a week or two? And I like the dish soap solution if you just want to be done with it.
Like I said I plan to use Thieves oil, all natural. Dish soaps are chemicals too.I will make one more remark.
It's a free country, so you can do as you please (within the law, which I think prohibits motor oil for this case).
However, I believe the YouTube video to be real (not faked). As such it shows the efficacy of the method there. Then why go with harsher chemicals, pouring those in *your* property, than dish soap if it is as effective...?
Just a thought. Don't want to fight, so I'll stop here and leave you to it.
