Today I noticed several Bees flying around our air conditioning unit outside. We have central air and the fan etc are housed outside. The fan was running and the bees were getting tossed up in the air. I looked all around the unit. There were so many bees ( as well as a few half bee bodies) I thought maybe there was a hive. Nothing. I turned the unit off and checked down in the body. I saw several dead bees inside around the base but the activity stopped once it was off.
I watched for quite some time looking for a possible hidden hive, nothing. I turned the unit back on and several minutes later returned to see bees getting tossed up in the air again swirling around and buzzing the unit over and over. There is a damp pipe they could have been getting moisture from but I didn't see any ladies there. We have a small pond and waterfall they visit for water as well as a pool. Any thoughts
