[Nhcoll-l] Killing dermestids from large cervid skulls

[Jacqueline Miller]

Hello Katrina,
I would adopt the second option, but I would not advise isoflurane.  Instead, try 1,4-Dichlorobenzene (what is used in "mothballs" or toilet bowl deodorant).

Hope you find this useful.

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!
-Katrina
