The Paynes poly floor has a monsterous landing board - much bigger than necessary.
That is utter nonsense Alfred..only kept bees for a short while but i nailed the wasp problem pretty quickly in the early day's....and i still use my method now with big landing boards in place with tunnel entrances into each hive..to date over my time using them i have not had any issues with full colonies getting bothered with Wasps/Mice or anything else all through out the year and into winter... Nuc wise is a different kettle of fish..
