I mentioned the value of stuff that works, be it organic or inorganic.  The organic example, also going to go on today if the wind stays down, is Milky Spore Disease.  This nasty little bacterium goes after Japanese Beetles, or more correctly their grubs.  It tends to remain active for about five years, before the number of incoming un-infected beetles out numbers the infected ones.  Most grubs die immediately from it.

This nice example of a very specific predation is what one would like to find for all those introduced pests.

Of course, the space alien baby squash bugs (I swear they look like a cross between a tick and a spider) I am just squishing.
