I put a nuc box with a drop of lemon grass right by my neighbors bees that had made a home under a wooden landing. Now, 3 wks ago we removed that hive (we thought we did) but now the bees are back. 3 wks ago bees were very well behaved even tho they were having their home taken away. NOW, last night when I put the nuc box down, 100s of bees came out from underneath the board and were mad as hornets. OMG, I was stung twice (no bee gear, my fault) Was it the lemon grass that up set them or the smell of the nuc box? (it was not the box that I thought had wax moths. I took your advise and did away with that one) Thank you. I was just wondering. I have not seen bees that mad before.
