How far apart should beehives be placed? This is a complex question to which there are many answers. This will depend on how you wish to keep your bees, and what your objectives are.
Ideally, bees need to fly out of the hive and see the Sun. This means it is easy for them to navigate, and it also means that they can start the day early and end late, as the Sun gives them a little bit of heat on colder days.
If it is possible to space your bees so that they are at least 10 yards apart you will have a lot less drifting, robbing, and a lot less anger in your bees. This de-risks your beekeeping.
This will depend on your house. Remember that bees will fly towards light – so if the house has lights that are visible to the bees, there will be problems. I have actually had beehives built into my house once!
