[NHCOLL-L:1859] RE: screening out pests

[Simmons, John E]

Dermestids can be as small as 2 mm.  Use a very fine mesh window screen.

Any possibility that you can drop the light fixtures below ceiling level so
that the heat is not an issue?  Then you could seal off the hole where the
wiring comes through.

Subject: [NHCOLL-L:1855] screening out pests

Hello all,

Can anyone advise on the ideal mesh size for window screening to best
exclude insect pests?  We are having a problem with insects gaining access
to the collections room from under the roof through the light fixtures.
We are going to try putting window screening around  the openings on the
top of the fixtures.  There needs to be adequate air flow to allow heat
to dissipate from the fixtures.  Any advise is welcome.

Thanks in advance,
Tamar
