> I now put the bees in around dusk or on rainy or snowy days.

Many beekeepers have figured out the advantage to doing so.

As Pete and Charlie have pointed out, there is likely a combination of
scents involved--queen pheromones, orientation pheromone, perhaps worker
cuticular hydrocarbons.

Bees can certainly be confused by rows of hives, but they live by scent.
