Most of the *Ptinus *beetles are capable of surviving very long periods without food or water - they seem to be able to keep a population going in cold, deserted buildings for months or years. When you mention "another big lot of them", that suggests you have probably got a local source of food - possibly a dead bird or mouse in one of the air vents? They are unlikely to do any damage to the type of collections you have. Continue good housekeeping, and ensure that humidity is low enough to discourage their relatives, the woodworm beetles. Tony
