Applying an Integrated Pest Management (IPM) approach, with the
minimal use of chemical insecticide is the best way to approach this
problem.  Thrips, Taeniothrip sp., can bite people, and the
carcasses can possibly lead to secondary infestations in the

If the person or group managing the building facilities does not
have IPM capability, then I'd suggest contracting with a Pest
Control Operator in the area who does apply IPM methods and can give
you a full assessment of the problem.  Most likely there is
vegetation right around the building which should be removed or at
least cut back.

Look for faulty door sweeps that might be allowing the thrips, and
other pests, to enter.  Same with window seals and other possible
structural entry points.

Step up housekeeping to remove dead insects regularly.  Seal or
reframe the artwork to exclude the pests with backing boards and
aluminized tape to seal the rabbet.

This website details a 'green' comprehensive thrip control approach
that is consistent with IPM in museums.
