It’s that time of the year when honey bees may swarm. For more information see https://www.bbka.org.uk/swarm. Bees are a beneficial insect and not a pest, we therefore cannot help if you have problems with bees and recommend you ‘leave them bee’
A swarm in May is worth a load of hay; a swarm in June is worth a silver spoon; but a swarm in July is not worth a fly.
Proverbial bee-keepers’ saying, mid 17th century; meaning that the later in the year it is, the less time there will be for bees to collect pollen from flowers in blossom.
