One was easy, hanging from an elevated flower pot about 4 feet off the ground -- just had to pick up the flower pot and shake it into the box.
The other was my neighbor's and was on the ground and around the base of a lemon tree -- clumped throughout a bunch of lower branches and tangled in tall grass so they were hard to scoop up in one unified clump. I baited the box with everything I had -- queen pheromone, lemongrass oil, old frames -- nothing worked. Once I was able to scoop up about 3/4 off the cluster and thought that would be enough for the rest to go in, but I leave for a bit and when I come back everyone's back on the tree trunk. Finally got em but took me numerous tries over several days.
