Hi has anyone any good ideas that work keeping ants out of Warre hives?
Large amounts in hive all day and evening.
Thanks in advance

Typically these are made by smaller colonies which are short on girlpower.
I note that both the casts I hived this year have made them, perhaps
feeling a bit nervous next to the two huge established colonies.
So far I have not seen evidence of robbing by other bees or wasps. The
recent rain should recharge nectaries so there should not be a severe food
dearth, which sometimes triggers robbing, for at least a fortnight; so the
barriers may never be needed. If the colonies become large and successful,
I would expect them to eventually dismantle the barriers as they will get
in the way of increased traffic and ventilation needs.
I talked with John Haverson in Hampshire a couple of days ago. He says his
bees have greatly reduced the amount of pollen going in - I have seen this
too. We assume this is because they have reduced the amount of brood they
are rearing as the June Forage Gap nears.
