Thanks for all the information. I shall have a read through these, it is good to know exactly how much damage they could cause, I'm still trying to understand what others in the IPM world count as a 'jump' in population? I am more than likely being over cautious as the increase is only in a couple of traps, and in single figures. All our stores are environmentally controlled and monitored and we are happy with RH and temp levels, I only use a nilfisk hoover with filters when housekeeping. Maybe it is because it rains so much here!

You can find a reference to it and other literature (most of which deals with free-living, rather than domestic species) at http://www.brc.ac.uk/schemes/barkfly/literature.htm Liposcelis can certainly do damage in a collection, feeding on insect specimens, for example. They will attack a variety of materials as well as mould. Starchy products are very attractive, so anything in the archives with starch-based glue will be fair game for them. Generally, the amount of damage is normally small, and associated mould growth is more likely to cause long-term problems. If you can achieve relatively low humidity in the archive stores, this will help. Also note that increasing housekeeping could make the problem worse if it involves damp cloths rather than vacuum cleaners.

Our RH is closely monitored by a BMS and local tiny tag systems, and has been staying within range. The housekeeping is done every few months, so I might just increase it for the moment and monitor, as it is only a very small increase in population.

They feed on microscopic mold which indicates that the relative humidity is too high. From personal experience I experienced a huge increase in population just prior to a mold out break. At the very least they are an environmental indicator. The good news is that they can be easily controlled through improved housekeeping and reduced RH. Good luck.

As far as I can tell we have a number of different types, such as Dorypteryx-domestica, Liposcelis-bostrychophila, Ectopsocus Briggsi and Psyllipsocus Ramburii. What I would like your thoughts on is - are all/any classed as a danger to archive material (books, textiles, photographs)? I use a number of different sources (online and books where possible), but if anyone knows of specific books that are handy for identification this would also be great!
