I'll tell you how to stop them coming back. You need scrape the hive site absolutely clean of any residual beeswax. Apply a fresh coat of paint on the surface where the hive was anchored. Then (optional) apply a lavish coat of petroleum jelly.

Otherwise bees will come back again and again. They're very sensitive to the smell of wax from older hives which marks it as a known-good place.

Hive appearances are seasonal, with bees migrating to and from the forests surrounding Pune. Typically they arrive in the city in greater numbers in summer, when water is an issue. They prefer east-facing locations, to avoid the wind on the western faces of buildings.

All this knowledge is from a team of senior experts in the Bee Research Institute on University road who visited our building - which has housed hives on and off for the last decade. Bee removing guys won't tell you about this, since it ensures a repeat order.

Personally I don't mind bees - they've never bitten any of us, except those who are foolhardy enough to smoke in their presence. But others in your society may have a more prejudiced view.

Do try the raw honey when they take it down, carefully squeezing the wax. Finicky types may want to pick off the dead/dying honeybees before feasting on their life's work. Light, golden and not as heavily sweet as the bottled version, with amazing floral notes. Eat local, eat organic, blame colony collapse on cellphone towers.
