I accidentally brewed up an effective one myself. Round when I must have been 8 or 9 or so, some neighborhood kids and I played at creating a brew in a trick-or-treat bucket by putting everything we could find in it, like grass clippings, some sand, leaves, some mushrooms we found lying around, just everything, and giving it a fairly aggressive stirring. At the end of the day it was time to dispose of it, so we poured it on top of a very large group of ant nests that had developed.

The next day, the ant's nest was gone.

In hindsight, it was almost certainly the mushrooms. Thank goodness we didn't have the kind of kids who would have dared each other to drink some... that could have gone legitimately badly.

Decades later, I mentioned this to my father and he recalled that there was this ants nest that he had intended to take care of, which he remembered for that long to give a sense of how out-of-the-ordinary this was. He was surprised when it just disappeared entirely one day, and perhaps just as surprised to find out decades later why it just disappeared.

Nobody needs to report me... I'll turn myself in.

Stop murdering ants.
