This picnic table is my neighbors, the green house in the background mine. They came knocking on my door about 8am after almost sitting down to an outdoor breakfast. Needless to say they ate indoors that morning. Mind you, these neighbors were well informed about my bees and they enjoyed watching me work the hives from time to time. If I hadn't spent time educating them it may have been a disaster.
Swarms can be plentiful when a healthy queen, agreeable weather and food is plentiful.
One year I had 7 swarms in a matter of weeks, they landed everywhere. It can be a humbling experience to see a quarter million bees bubbling out of the hive and into the air. So as COOL as this looks , it can be your neighbors worse nightmare. Bees will land on anything that seems capable of supporting their weight and they could be there for days until the scout bees find a favorable home. You need to know that swift response is expected if you hope for friendly neighbors.
