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 collections. 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. <URL:http://www.planetnatural.com/pest-problem-solver/houseplant-pests/thrips-control/> Paul S.
