/diy/ - Do It Yourself

What I did to a nest of ground wasps that had been attacking my dad and me:

1. I poured concentrated bleach at the hole.
2. I poured concentrated hydrochloric acid at the same spot, and quickly stirred it around with a stick.
3. I put a large plastic bucket over the hole, with a stone on top.
4. I waited.

The acid reacts with the bleach and forms chlorine gas. Chlorine gas is very poisonous as well as heavy and therefore makes it way down to the lowest levels of their infested dungeons.
It has been used as a mean of chemical warfare - mainly for trenches.
Not to mention that many wasps get simply corroded to death.

We had no problem with ground wasps at that spot afterwards.
