I am researching ways to eliminate difficult yellow jacket (wasp) ground nests without using dangerous chemicals. Does anyone know of a commercial machine that is made to inject large quantities of dust into the ground or other void? If not, any clever ideas if how to make one (maybe with a compressor)? I would like to experiment with the injection of nests with diatomaceous earth.
I need to do more research on how effectively the DE kills Yellow Jackets. What I do know from my own experiments is that they avoid contact with it in a big way. After filling the nest entrance with DE, they will spend a lot of time digging a new tunnel around the DE rather than clearing the existing hole of DE
