Friend Wheel Bug! I love wheel bugs, so personally, if it was me, I'd just let them eat the bees.
They probably don't catch more than a few a day anyway. Or better yet, just pick them up and move them to your garden. My mom found one in her garden last week, caught a Mexican bean beetle, set it in front of him, and he nailed it immediately! They are usually quite docile, but their bites are very painful (although not highly venomous or dangerous), so do wear gloves or be careful not to antagonize them if you pick them up. They put their first pair of legs in the air and do a little ninja dance when they feel threatened.
I found a final instar nymph on our sidewalk the other day, coaxed him onto a stick and then onto my sweatshirted arm, and he was cool just hitching a ride to the garden. As you say, they are phenomenal for garden pest control, as they are an apex predator of the insect world. If you put them near another food source, I doubt they'll move back to the bees.
