[Nhcoll-l] Advice for pests in collections

[Mireia Beas-Moix]

Hi all,



We discovered a cigarette beetle pest infestation in one of our herbarium
rooms. We bagged the specimens, proceeded with the two-cycle freezing
treatment and cleaned the cabinets thoroughly. However, the cabinets in
that room are old and do not seal properly.



We follow an integrated pest management program for our collections and
avoid the use of chemicals. However, in this case we are considering
spraying the cabinets with some pesticide to eliminate any possible beetle
remains and avoid the development of a new outbreak.



After some research, it looks like pyrethrum has been used in some
collections, although others mention that it did not work at all. What is
your advice?



Thank you,
