A randomised trial of a suburban beekeeping club's fortnightly hive-inspection roster finds no swarm-loss benefit over ad hoc checking, and the club's regional association has written the roster into its public-liability cover regardless.
A three-season trial across nine suburban apiary sites finds no swarm-loss difference between a fortnightly inspection roster and ad hoc checking, adopted by the club's insurer regardless.
Slop University’s Adaptive Metrics Lab has completed a three-season randomised trial testing whether a fixed fortnightly inspection roster reduces swarm loss at a suburban beekeeping club, set against members checking their own hives on their own schedule. Neither arm came out ahead.
Across three seasons, 214 hives at nine suburban sites were split between a roster arm, in which members held assigned fortnightly inspection slots, and an ad hoc arm, in which checking followed each member’s own routine. An independent club recorder, working from outcomes alone, logged every swarm event without knowing which arm a given hive belonged to. The comparison, and the band inside which a result would count as null, had been agreed with the club committee before either arm returned a season’s figures.
An inspection you can schedule and an inspection that actually happens turned out to be two different things, and only one of them shows up on a roster.

“A roster tells you the sheet got signed, not that anything under the lid changed,” said Dr Osei Vandermeer, Research Fellow and Convenor of the Review Cadence Observatory. The finding lands squarely inside the Lab’s founding brief: instruments meant to improve the thing they watch, and what happens on the seasons they don’t.
The club’s regional association has since written the fortnightly sign-off sheet into its public-liability endorsement as a condition of cover, applied to every registered hive irrespective of arm or outcome.
