My husband left the cover off our top bar hive after inspecting the combs and it rained that night. We let the surface dry out and replaced the cover. I don't think the inside of the hive itself got wet ( I can't be sure), but now the surface edges of some of the bars look green, like they have mildew or something from the moisture. Also, we have been noticing a LOT of bearding after those heavy rains. So 3 questions: If rain water had gotten into the hive is that a problem? Is there a a safe way to get rid of the mildew or whatever it is on those bars? Is the bearding a sign of something wrong in the hive (like too much humidity?). Thanks!
