Here is what it says on sialis about mites.
Mites (Acarina) or Lice Numerous tiny black or red dot-sized bugs crawling in nest/on babies, especially in Tree Swallow nests. Adults may act alarmed. Birds fledge prematurely (esp. martins). Not common on bluebirds. Provide TRES with clean feathers for nesting, do a nest change, or use a low-level (0.03 - 0.1%) of Pyrethrin pesticide, under nest. Burn used nests. Take care not to transfer mites to other nests on your hands/clothes.
This is a great website for everything you need to know about cavity nesters.
