Has anyone else heard about this? Seems to me that it would be a simple thing to breed some cockroaches (yes, intentionally ) for the purpose of making large quantities of bug repellent.
I'd try some tests of my own, but I think I've reached my wife's mad scientist limit with the rocket stove and tree care tinkering - breeding large quantities of bugs is too much to ask, at least until we have a little more land
