Good morning, colleagues - My first thought is that more information is
needed. For example (in no particular order):

To what kind of textile/fibre/dye/attachments will the Gentrol be applied
to? In what form will the Gentrol be applied? What concentration? What else
is in the solution applied? MSDS looked over? Left on or just left on until
the textiles are subsequently treated (cleaned/washed/conserved/repaired)?
Does the manufacturer itself recommend the use of Gentrol for the control of
this particular beetle (and not just the licensed pest control operator)?
Have the beetles been identified by an entomologist-type professional?

Hello all,

I am posting a question from a curator in a history museum. She would
like to know if anyone on the list has had experience with or has
comments about using, Gentrol which is S-Hydroprene, a growth regulator
pesticide  for dermestid (carpet) beetles.  Thanks, Sandy
