Heather - Female webbing clothes moths lay up to 300 eggs each! Populations can explode "overnight." Trapping males in a pheromone trap often happens after females have already been impregnated. Finding any males in a trap is not a good sign. WCM's are the most difficult and damaging pest any collection can have. You must aim for 0 moths.

Not within individual cases, but the building as a whole. A routine trapping schedule will tell you when a problem is escalating, but once it has been treated ( assuming that no treatment will be 100% effective) what, if any levels can you live with?
