Also make sure no one is baiting for rodents inside. The baits can become 
carpet beetle playgrounds as well. Only bait on the exterior of the building.

I have found that inspecting and vacuuming above (ceilings, light spaces in 
cases)  and below things( under cases and supports) is super important with 
carpet beetles. Check void spaces and utility chases near or adjacent to the 
space. Dead crickets, rodents, or even bird nests on an outside eave can be 
carpet beetle nurseries. This is where they lurk while you freeze and clean the 
usual suspects. You can have your pest company dust under cases and in voids 
with a product called cimexa this is an amorphous silica gel dust. Exterior 
perimeter sprays may help you will have to trial that and see.  Try pheromone 
traps they can point you in the right direction as to where they are getting in 
or are nesting in detritus. Throw everything at it. JTV

Hello wise pest listers!

We have been having trouble with larder and carpet beetles in a building.  We 
have exclusion issues with that building.  Doors and windows need to be sealed 
better and we have foundation issues with occasional flooding with heavy rain.  
There are significant issues with flies that we constantly fight.  The dead 
flies and weak building envelope are a real challenge for allowing and drawing 
in pests.

There are not a lot of objects on display in this building and no collections 
stored there, thank goodness.  I have had to freeze some objects with feather 
and leather that were infested in the past year.

I am working on having all objects that are most susceptible to damage from 
these types of beetles restricted from display in this space (leather, 
feathers, organic/protein sources) but removing them is a challenge because we 
do not have room in storage for them.  We also need to address the building 
envelope issues, but facilities planning isn’t going to happen until this fall.

In the meantime, is there an approved PMP method for control, i.e. spraying 
around the exterior of buildings, etc. that could be instituted to help control 
things as they sit now?  Would pheromone traps help monitor and/or control 
better than the sticky traps we are currently using?

I am tired of this drip, drip, drip of problems related to this threat.  Right 
now we are only able to react after-the-fact, when we discover another beetle 
or damaged object.  I’d appreciate any words of wisdom and advice about a more 
sound way to address prevention/mitigation.

Thanks!
