That's it, the little red thing just below her wing. Again, not something to get freaked out about, we all have to deal with mites.
I remember when I first started I had this bizarre idea that somehow my bees would never have the problems other beeks bees had. :roll:
That idea left pretty quickly, no one is immune.
I think of mites like fleas and ticks...if you've got a dog that lives outdoors or goes there often, that dog is *gonna* have fleas and maybe ticks. You'd want to make sure the dog doesn't get so many that it makes her sick, but just seeing a few doesn't mean you have to run out and do a full on flea-dip on her that day.
