Todd, it could happen sometimes, that you catch other moths, like Plodia interpunctella or Nemapogon cloacella with a WCM-pheromone-trap.
In one museum we had an infestation with Sitotroga cerealella, also catched with normal Killgerm-WCM-traps. I think this could happen with other compounds of the traps, like solvents of the glue, who are attracts the males of different moths. The most important thing for me is, to look for WCM as the main museum pest on sticky traps and avoid the confusion with similar looking moths.

The sticky trap is baited with a pheromone lure that specifically targets webbing cloths moths (Tineola bisselliella). I noticed 2 moths stuck inside that did not resemble normal classic webbing cloths moths. My first guess was they were Case-bearing cloths moths (Tinea pellionella). I wondered why there would be 2 Case-bearing cloths moths in a trap with a webbing moth pheromone. If it was only one, I would guess it flew in there accidentally, but two makes me wonder if they were attracted somehow. 1) Have any of you ever experienced Webbing moths/Case-bearing attracted to the opposite pheromone? I looked around online for a while trying to find good quality images of Case-bearing moths to compare, and found other types of moths that resembled it pretty closely ("Niditinea fuscella" and "Niditinea orleansella" to name a few). I started digging deeper, and didn't realize how many different moths there are out there in the family "Tineidae". It seems like 99.9% of the time we only hear about the Webbing cloths moth and the Case-bearing cloths moth. Given the nature of how they were in a trap with a "Tineola bisselliella" pheromone, and are not webbing cloths moths, I feel like theoretically they could be anything. 2) Based on this picture (sorry about the quality), how certain can one feel that they are Case-bearing cloths moths vs some of the other lookalikes? 3) Generally speaking, in museums is there a reason that we never hear much about the 100's of other moths in this family other than the "Big Two" Webbing/Case-bearing? 4) Hypothetically if these were not Case-bearing moths but still in the Tineidae family ("Niditinea fuscella" and "Niditinea orleansella" for example), should my concern be the same as far as threat to a museum collection? In the meantime, I will place some Case-bearing pheromones in the area and see what happens. If anyone has any thoughts relating to the questions above, I would be very interested in hearing your thoughts! Thanks!
