The chemical you could use is Bifen IT, it has over 75 different insects on the label so it's a good general insecticide. You can spray where you have seen the most activity and it will provide a contact kill that will affect their nervous system and they can spread it throughout the hive. It is safe to use indoors and outdoors. You will mix at 1 oz per gallon of water and spray over 1000 sq ft. It is pet and child-safe as long as you are not treating while they are present and then for at least 2 hours after application to allow it to dry.
Another option would be to use Tempo 1% Dust, it will kill bees that contact the product and those they contact may also be killed by grooming each other and spreading it.
