Tons of them this year, my entrances are small but they are stalking the hives some. There used to be a trap made with a 2 liter bottle, a 1 inch hole drilled in the side about 2/3 of the way up, water, banana peel and a little applecider vinegar, one drop of dish soap in the water (and water maybe 4 inches deep). A hole drilled in soda bottle cap, string thru it, piece of hot dog or other meat on string, hung just a little below drilled hole. and find a way to hang in apiary, I think I used a cup hook in the same hole the string went thru. Did that make sense? I've searched old site and BS. Can't find. Can't get search to work on here.
