The pesticide fipronil which is used in agricultural crops and termites in buildings has been blamed for the deaths of up to 10 million bees in southern New South Wales.
According to Beekeeper Mr Carter, one drop of this poison from one bee that takes it back to the hive will then kill the whole hive.
Five beekeepers lost the bees from 340 Hives in April after they were poisoned by the pesticide.
