Hi -
Just been out to look at our hive. It’s about 4 months old, filled with a swarm but the colony is a small one. It seems we have some European Wasps in the hive. I can seen the crawling around in top of the excluder bewtween the brood box and the supers. The bees have not yet moved in to the supers. I saw a wasp enter the hive. The bees seem as active as ever. Would love some advice!
