[Strawbale]SB critters and how to get rid of them?

I did a local search on Psocids, seems they are a bit of a problem in our
Australian grain industry. The following 2 sites give a some insight into
how these mites respond to the environment.

This second article is not for the faint hearted - apparently  their
capacity to reproduce will one day make them the dominate race.

Good luck
