Dear Mark:
Generally, honey bees will allow entrance to their hives only to
bees that share their "mark" of pheromones or to bees that come to their
landing laden with food
or water. Any others are generally chased away. Hence, your condition
seems highly irregular. My only guess is that your bees are not yet
quite impregnated with the pheromones of their new queen and thus are
allowing others in. Not to worry, if you have a strong enough
population in those hives, they will soon chase away those robbers that
come in looking for a free meal. One thing to do is to make sure that
you reduce the entrance to your hives. This might be contradictory at
this time though. During the summer season you want to make sure that
the entrance to the hive is free and allows lots or air circulation.
Use common sense. Good luck.
Best regards.
