Bees Nesting In House Walls

Bees nesting in house walls has driven me crazy for half of my life. Every spring, I will get phone calls from people asking why do bees keep coming into my house? 

The first telltale sign that there are bees in your walls will be that they will be flying consistently in and out of a hole, or gap.  There will be at least a few bees per minute when it is warm.

Bees nesting in house walls is particularly problematic in bathrooms, as many people leave bathroom lights on at night.

If a bee are nesting in a house wall within line of sight of your house and can see lights, some of the bees will fly to these lights at night.

The wall is opened up, the combs are removed and the bees are taken away.

Bees leave the hive in the wall, then go out and forage and when they come back, they join the other beehive at the entrance.

Bees are cavity-nesting animals. If you fill the cavity, they cannot move into it. I find polyurethane expander foam is an excellent way of preventing them from returning.

Good flowers or something made it nice to them. Other swarms will make the same decisions.

ADVICE

If a beehive is not managed properly it will produce swarms. Swarms move around looking for a specific type of place to build a nest. Normally a swarm will move into a wall around midday.
