<p class="MsoNormal" style="background-image:initial;background-repeat:initial"><span style="font-size:10pt;font-family:Arial;color:black">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.</span></p>

<p class="MsoNormal" style="background-image:initial;background-repeat:initial"><span style="font-size:10pt;font-family:Arial;color:black">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.</span></p>

looks like pyrethrum has been used in some collections, although others mention
that it did not work at all. What is your advice?</span></p>
