I got about 15 hives in my backyard and simple can’t keep the ants away from the hives. Even right now they are covered with small, black ants. At first I bought some white powder, boric acid and made a line around the hives. After a while, at my surprise ants were jumping over the boric acid.
I put the hives on pallets with legs and the legs in cups of oil (it is not the best idea – pollution). As soon as a fallen, dry leaf made a dry bridge over the oil they were back in the hives. Now I used some chemicals from Wall-Mart, but with no results and I am afraid not to harm the bees using pesticides.
Can anyone give me a suggestion how to handle this ant problem? Probably I can move away the hives if needed.
Thank you a lot.
