I removed the top feeder with the following observations:
- feeder was dry of syrup
- A carpenter ant nest had moved in 100s of ant winged and unwinged in the black basen
- Hive bees agitated beneath the screen
Removed the feeder nocking ants to the ground. Replaced with Queen excluder and two honey supers (C & D). Honey super C has no built up wax and is closest to the hive bodies. Honey super D was harvested from last year and has wax, it is the top most super.
Removed empty tin of Apiguard from hive.
Hive looked healthy, with minimal activity at entrance
