Vapona in UV light traps

[Charles Bird]

I hope to do some serious light trapping for moths this summer. With this
idea in mind, I have been talking with a number of people, plus reading up,
on the best kind of killing agent. Two ideas seem prevalent, ethyl acetate
and vapona. A problem with the first is that it tends to make the specimens
brittle, a problem with the second is that it permeates the plastic tub
also the fumes remain resident for a long time and could cause health
problems. I am hoping that some of you might share your thoughts on which
is best, or if I should consider yet another alternative.
