people ,
well late spring and the girls are ...well...busy as bees !!

i have three nucs that i would like to use as traps - i have placed three old "black" drawn out frames in them and a dab of lemon grass oil in each nuc -

each one is on the edge of the woods with water and open area nearby , all three face east - actually i placed them on deer stands !!! so all three are about 15 feet off the ground -

what have i forgotten and what swarm lure do you recommend ??

thanks in advance for your help ,
imc
