It is quite likely that you are confronted with the multi-colored Asian lady beetle, which are known to hibernate en masse in buildings. They are here because of a poorly thought out importation a number of years ago. It is not likely that they will do any damage to objects within your facility but certainly, they can be a nuisance. Looking forward, the solution is this: carefully and completely seal all exterior cracks and crevices, utility penetrations and other such points of entry in the exterior of the building. Make certain that all doors and windows close tightly (check the door sweeps) and that all screens are in good repair and tightly installed. Finally, and only if they are creating an unbearable nuisance or hazard to visitors and staff, you might consider power-spraying the exterior. Usually only the south and west-facing sides are necessary. Be certain that the chosen product is labeled for this pest. But consider this move only as a last resort, never as a stand-alone measure.
