Why?

They called and said the bees had come back.  I didn’t understand till they said they had sprayed them with bug killer and they had left.  I told them they should leave and told her to call back if they don’t move.  They didn’t so we went out and grabbed them.  They were ready to get off that wall.  I scooped them into a nuc and they just went right in.  If they survive they will take a long time to grow because of how small they were.
