How to make a fly trap
Duncan sent me this plan
for a nearly free, homemade fly trap that he made out of a plastic soda
bottle. The top of the bottle turns into a slippery funnel down
which the insects slide into the trap zone. Although a few might
find their way back out the small opening, it looks like in practice
most insects aren't that smart.

Duncan's goal was to
keep down flies that sprang up around his chickens, but I can envision
using the same setup as a homemade Japanese beetle trap and others on
the internet use it to catch stinkbugs. Since chickens are at the
top of my mind, I'm tempted to make a trap like this with a solar LED
light at the bottom to snag nocturnal insects to feed the
chickens. (The only thing holding me back is the lack of plastic
soda bottles in our trailer at the moment!)
