[Nhcoll-l] Antw: Re: Killing dermestids from large cervid skulls

Tue Aug 5 01:13:08 EDT 2025

I am also familiar with high-temperature treatment as an effective
method. But to be honest, this procedure gives me stomach ache.
Especially when it is used on skulls. The reaction to the heat could
cause the cranial sutures to loosen and the teeth to fall out.

Have you thought about a heat treatment?  This is very effective - see
Museum Pest Network or Tom Strang’s research on CCI.

does kill off little critters effectively. I used to use it in taxidermy
cases and entomology collections until it was banned from use in the UK
being an organ-chlorine!  It dissipates quite quickly and I find it more
effective than naphthalene which was in UK mothballs and can make one
feel woozy!

Instead, try 1,4-Dichlorobenzene (what is used in “mothballs” or toilet

>> Hi folks,

>> I'm looking for some advice on how to proceed with some large cervid
skulls I've got in my bug colony. One is a bull elk with a full rack,
the other is a mule deer buck, also with a full rack. I don't have a
walk-in freezer and none of my freezers are large enough for these
skulls with their racks. The skulls are clean and I need to move them
out of the bug colony, but I'm not sure the best way to get rid of any
stray bugs.

>> Options I've considered:

>>    •

>> Bagging them up with some dry ice (will sublimate fast though, a
little pricy)

>>    •

>> Bagging them up with isoflurane-soaked cotton (maybe not a good use
of veterinary-grade drugs)

>>

>> But I am open to suggestions if anyone has dealt with something
similar.

>> Many thanks in advance!
