If the infestation is wide-spread, it is likely there is excess moisture present that must be located and the resulting high relative humidity eliminated. Spread the records out in a cool, dry location with plenty of air circulation. This should drive the pests away. As long as proper conditions are maintained, any eggs left behind will not hatch and offspring will either not survive or move on to a more hospitable environment. My records have mold growing on them.
Mold grows in areas with high temperature, high relative humidity, and low air circulation.
Once record materials are removed to a less hospitable environment, the mold will become loose and powdery as the substrate dries and the mold turns dormant. It may then be gently brushed off the record materials. Because the mold is merely dormant, if it remains on the record materials or is distributed throughout the space and onto other objects, it will grow whenever environmental conditions are favorable again. Ideally, the faster record materials are dried the better. However, some record materials may distort physically if dried too quickly.
