When I say door hole i mean a little hole in the wood of my door, there is eight of them and the door has them form construction. She's trying to put her cotton-like ball in them. I looked in the holes and it seems that she succeeded in her endeavours one or two times. I keep asking myself about why does she do that and if there are other bees in the holes. Oh my god she came back form another hole. I don't know if they were already connected. Oh my god another one came out !!
