Checked varroa inspection boards after one week in place. Two give the impression of good sized clusters with only three varroa between them.
Third colony, no varroa dropped but eight severed bee heads, some abdomens, legs and wings.
I'm thinking from fights with wasps?
This colony, although heaving with bees through into late September, seemed to allow wasps in - often removing them when dead - but lacked the defensive spirit of my other two colonies. The cluster size is smaller than I would like to see.
Any thoughts anyone?
Resident mouse?
