Regarding the use of UV light traps in a museum storage:  After
discovering artifacts infested by powder post beetles in our
off-site storage area, we decided to try UV traps since we had no
success in trapping these insects with sticky traps.  We rented the
traps from a local pest control company since we were not very
confident that they would work.  As predicted, they were not
successful in capturing any powderpost beetles or very many other
insects (we kept them for a year).  A few small flies were found in
a trap near a poorly sealed door, but on the whole, we found that
sticky traps were more effective than the light traps for capturing
insects (other than the powder post beetles).  I would definitely
recommend renting the traps before buying them. Also, we used them
in an space that was infrequently used so the hazard of working
around them was minimized (signage warned staff that they were in
use and the lights were directed away from the artifacts to protect
them as well).
