Hello Marion, There is only one pheromone lure out there that has any attractancy as far as I know. This is the Japanese HIRESIS trapping system. I have tested this and found it to be attractive. The pheromone for* Stegobium paniceum* is a complex molecule and the HIRESIS lure for it is a mimic rather than a true replica of the insect pheromone. It is a more stable chemical than the true pheromone, meaning it won't break down and turn into something else in a short period of time. It is a decent option for monitoring. You would want to space the monitors 3 - 5 meters apart from each other in the areas where you suspect activity. Under normal room temperatures, it should last approx 6 weeks. It is a sex pheromone, so you will only be attracting males.
I have tried attracting them with wheat germ oil and found no attraction. This was performed in a museum storage area though and the population there was feeding on a diet of proteins other than grains. There is a possibility of some attraction if their diet is grain-based, but it is unlikely in my estimation. Other food attractants in a sticky trap will also give poor results unless the population is so large that they are attacking anything that is a potential food source and in these conditions, you already know that you have a problem. Finally, UV light is extremely attractive to the adults (male and female) of these insects. They are strong fliers and can fly into a fly-light trap across a room or on a wall. Of course, in a museum setting, we all know the potential damages that UV light can inflict on some materials and these precautions must be considered. Light traps can give good information about the presence of Stegobium, Lasioderma and many dermestid species. I hope that this helps.
