The bee was probably dying already. The ants are like sharks below my colonies waiting for the dead and dying to come on down. I used granules to keep them at bay here in fire ant heaven, and it works to a degree. i do watch them carefully....as if they decide to go after the hive, it wont take long for them to do it. Its kinda like shb, the bees can't sting them but they can bite them and fly off with them, and I have seen them do it before!
