Pat - I might add - in urban situations, the WCM's are not following people; they're following pigeons. Nesting pigeons are a huge urban source of natural WCM infestations. To a lesser extent, certain dermestids are commonly found in smaller bird nests, especially English sparrows. They are also common in mud dauber and wasps with paper nests.

When searching for specific infestations, pheromones are one of the best tools out there to focus our attention of where to inspect in large storage areas. It always comes down to a visual search, but pheromones can narrow the search to a much, much smaller area. Sex pheromones are only going to attract the male of the species, not a female with eggs or a reproductive pair. If breeding is going on in your storage or exhibit space, it was already there before the pheromones were introduced. Many of the topics at the recent "2011 A Pest Odyssey" meeting in London showed how pheromones were used in museum settings to monitor and locate infestations of webbing clothes moth. The publication of these topics just came out in December of 2011. http://www.pestodyssey.org/publication.php If you are worried about drawing in native populations living around the museum, you should keep the traps 15 meters away from any door that gets left opened on a regular basis. (Although I will say that if you are in this situation, you would probably be better off spending your time and resources to find a way to exclude outdoor pests with better door sweeps, lighting, screens and other exclusion methods. Another good way is to keep the door closed!) If webbing clothes moth is the insect giving you the most problems, recent research has shown that you don't have to worry about drawing them in for outdoors if your museum is in a rural setting. Authors; Rudy Plarre and Bianca Krüger-Carstensen in their paper titled: “Outdoor trapping and genetical characterization of populations of webbing clothes moth Tineola bisselliella (Lepidoptera: Tineidae) in the broader area of Berlin” published in J. Ent. Acaral. Res. Ser. II,43(2):129-135, Sept. 2011 showed that outdoor trapping in rural areas did not catch any moths, while numbers outdoors in the city were relatively high. These moths are clearly following people! Research and testing of multiple pheromones being used in single traps has been going on for many years and it continues. It often depends on the species you are trying to attract as to how well it will work. If you are just starting a monitoring program from scratch, I always recommend to first monitor with sticky "blunder" traps, then identify what you find and finally locate the source with pheromones only if there is a reliable sex pheromone available for that specific insect.

Unfortunately most insect species have one or more pheromones (let's say sex pheromones) specific to that particular species. There's no such thing as a "general" pheromone, which can be synthesized for a range of species. There might be a common bait attractant for, let's say, the more common cockroaches. Or some kind of food attractant for the dermestids. Perhaps that might be an avenue to research. By the way, it is not true pheromone traps will entice insects into a museum. Pheromone trap lures do not have extensive "reach", i.e. they only cover a fairly small square footage of area. So unless you put a webbing clothes moth pheromone trap just inside your dock door and you have a pigeon infestation on the roof nearby, such a pheromone trap would not "draw" WCM's into your building.

I agree with Tom - blunder traps are very effective in identifying the species that are present in a museum - both pest and non pest species. They are also an inexpesive way to start determining population density and distribution. These are the first steps that need to be taken with IPM. Pheremone traps, when used properly, are good for focusing in on specific pests. Pheremones target specific species and not all museum pests have had their pheremones specifically distilled. We are not the primary market. In addition, pheremones attract only the male of the species. Blunder traps and pheremone traps are useful tools for monitoring pests only. Not for eliminating pests. Hope this helps.

What you describe is what you say it is; A blunder trap. There is no doubt that the advances is pheromone technology has enabled the development very effective and accurate monitors, capable of detecting very small or new infestations. Blunder traps simply demonstrate how severe an infestation has become. For insects and even mice to be caught this way indicates severe infestations. Not something of much use when you consider many museums following good IPM protocols regard one moth as a serious infestation! I’m not ‘re-inventing the wheel’ but rather trying to develop something which may bring us into the 21st century. A trap with a number of pheromone lures which will attract insects even if there are very few around; at a fair and reasonable price. I can well understand museums using ineffective blunder traps, particularly when we all have to control costs. What I am trying to develop and offer is something in a similar price range which actually works!

Even flying insects end up in these "blunder" traps. Not only can you determine the kinds of insects getting caught (indoor or outdoor), you can often determine from which direction they're coming. As an added bonus, mice can be caught on the larger ones. And they're cheap! Let's not reinvent the wheel.
