I know it ain't the best method or most popular but I always used mix gas (weed water or chainsaw) pour it down the hole. About a gallon give or take. I always threw a fuse on them an BAM light show with fire at night and now more bees. But it does tend to kill the grass for a bit.

I would rather be tried by 12, than carried by 6.
