wish i knew more about the raising of bees, 2009 i had bees all over the neighbourhood, 2010 i could count the number of bees on 1 hand, think i even made a post about the lack of bees in my area.
After interacting with HawaiiAl, he put me onto the spreading of anise oil to possibly attract bees, i couldn't find the oil essense but i did have anise seeds, so i made a tea and put it into a spray bottle and periodically sprayed around the house.......don't think it work....possibly because there were so few bees to attract.
