Bees can slip through cracks as small as 1/8 inch. Gaps around vents, windows, or siding give them an easy way in—especially if a wall is hollow or warm.
1. Tiny Cracks, Big Trouble
Unused chimneys and vents act like open doors. If there’s no screen or cover, bees find their way through and into the cozy spaces behind your walls.
2. Chimneys & Vents Are Doorway
Wall cavities are warm, safe, and hidden from predators. To bees, that’s prime real estate! Once they find one, they move in and build their hive fast.
3. Attracted to Wall Cavitie
Scout bees look for nesting spots and follow pheromones left by the queen. If she picks a wall, the whole colony comes buzzing in behind her.
4. Following the Queen’s Scent
Storms, sudden cold snaps, or strong winds can push bees to take shelter. A crack in your wall is a dry, safe space when outside conditions turn rough.
5. Weather Can Drive Them In
Old hive scent lingers. Even if bees were removed before, the smell of wax and honey can invite new swarms looking for a ready-made nest location.
6. Previous Hives Attract More Bee
Rotting wood, broken bricks, and loose siding offer easy entry points. Without regular checks and repairs, bees will find their way in sooner or later.
