Have you tried flipping or scraping some of these covers to see if they are moist or gooey underneath (live)?
You could use a stiff brush to remove some of the live ones if found and reapply dormant rate of oil.
Any time now would be appropriate to use a dormant oil again (follow label instructions). Be sure to get complete coverage of wood.
