Just with regards to possible sources of infestation, are there any rodent
baits in ceiling voids or to offices, etc.?
We have also had a huge issue with Stegobium and Lasioderma in starch-based
packing noodles. The noodles have been used to replace inorganic styrofoam
packaging, but it is very attractive to beetles. Several infestations of
collections have been traced back to this style of packing material.
Best wishes

Joel--


Thank you for your suggestion. After we perform our second aerosol treatment, 
we will implement pheromone traps. The collection is near a couple faculty 
offices, molecular and zoology lab spaces, and hallways with a couple vending 
machines and trashcans. Insects don't seem to be an obvious problem out there, 
but food and drink are potentially nearby.

Hi everyone,



I am the Collections Manager at the Angelo State Natural History Collections. 
We have a persistent pest problem with a number of insect species entering the 
collections (seasonal crickets, ground beetles), but only a few that are 
imminent dangers to our collections--what we believe to be drugstore beetles 
(Stegobium paniceum) in the skins collection, and clothes moths (Tineola 
bisselliella) in low density in a skull collection where wool was formerly 
stored. Please see the attached photos for what species we are dealing with. We 
have historically used freezing and isolation to manage pest outbreaks, but the 
degree of pest exposure is greater at this time. Our collection cases are 
elevated, the door seals are generally in good shape, and we use and monitor 
sticky traps



Specimens--and, at times, cases--with beetles are frozen at -20C for 2wks when 
positive for pests or pest frass, but the number of cases with pests exceed our 
freezer capacity. Live drugstore beetles have been found in one collection room 
on the floor as well as on the tops of cases. We have fogged the room with 
CB-80 (0.05% pyrethrin, nonresidual) with case doors closed. We plan to fog 
again two weeks after this initial fogging to catch any larva that may have 
hatched since the first treatment.



The collections room has some degree of shelving, books, etc. that may harbor 
pests. Fogging the room we hope rids them from those habitats. The collections 
are housed within an older biology building. We don't have the resources to do 
major facilities work, but if there a

Hi everyone,

We have a persistent pest problem with a number of insect species entering the

imminent dangers to our collections--what we believe to be drugstore beetles

The collections room has some degree of shelving, books, etc. that may harbor 
pests. Fogging the room we hope rids them from those habitats. The collections 
are housed within an older biology building. We don't have the resources to do 
major facilities work, but if there are suggestions for better sequestering our 
collections through some facilities upgrades I'd be glad to hear it. There are 
drugstore beetles in rooms within the biology building outside of the 
collections and I fear they simply re-enter after we fumigate. Tight door 
sweeps have been installed and windows (where they exist) have been re-sealed. 
I am working on potentially getting additional filters or fine screens 
installed for our HVAC ducts.



My questions for you all:

  1.  Are we correct in our pest identifications? Striations appear on the 
elytra of the beetles, and they do possess the characteristic antenna of 
drugstore beetles (though this doesn't show up in my photos).
  2.  For drugstore beetle infestations in particular, does anyone have 
specific recommendations?
  3.  Is anyone using fogging? Did you leave the doors to your cases open 
during fogging? Has anyone used CB-80 as a museum-approved aerosol?



I would be happy to provide additional useful details. Thank you in advance.



Dianna
