Where you place hives is important for minimising nuisance to neighbours.
Manage bee excrement: Make sure you position hives in a way to avoid excrement dropping on neighbouring washing lines, vehicles and buildings.
Manage flight paths of bees: Bees will fly at head height for some distance from their hives unless their surrounding environment directs their flight path upwards. Bees can be encouraged to fly above head height if you place a flyway barrier 1-2m from the hive entrance.
Barriers you can use to direct a flight path include: a shrub, trees, wall, hedge or a fence.
