Factors promoting infestations of the webbing clothes moth (<i>Tineola bisselliella</i>) were found to be storage of soiled protein materials and poor housekeeping. Procedures for monitoring, containing and cleaning up infestations are outlined. Monitoring is done using inspection, sticky traps, and pheromone lures. Annual resources required to monitor a collection of one million objects in 7,830 m² of storage and work space comprise 112 person-hours and U.S. $1,300. Containing and cleaning up infestations in collection areas is based on freezing objects, vacuuming and washing storage facilities, and removing insect residue from objects. Resources required for an area 16 m² holding 400 objects comprise 515 person-hours and $300 of materials. Most staff hours were used in removing insect residue from objects. Containing and cleaning up infestations in non-collection areas was based on vacuuming and washing, with material being discarded or frozen. Average required resources comprise 35 person-hours.
