Subject: Question about Cyanide Gas (for a good cause :-)
I'm not much for the chemical reaction part but I've used calcium
cyanide to kill things. ;-)
When I was keeping bees a few years ago the local inspector gave
me some to kill a hive that was infected with foulbrood (a bad
disease for you non-apiarists). It was a gray colored powder with a
heavy, musty odor. Really noticeable once you've smelled it.
A tablespoon killed the hive (~3.5 cu ft) in less than a minute.
I don't know what the concentration was though.
It also worked great in my killing jar that I used for collecting
insects. The teaspoon that I put in there was still effective
several years later.
