While reading another
thread about using a bone sauce as a nibbling animal repellent, it reminded me of an article I read a couple of years ago about dead cockroaches giving off a scent that will repel other bugs:

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
