Can Bees Damage Your House? Wax, Honey Leaks and Stains
Homeowners ask us can bees damage your house almost as often as they ask whether bees will sting. The short answer: honeybees themselves aren’t wood destroyers. UGA Extension notes that bees don’t cause significant structural damage (UGA Extension C824). The trouble comes from what a colony builds and stores inside the wall: wax comb and honey. Left in place, those can stain walls and ceilings, attract pests and draw new swarms.
Can Bees Damage Your House? Where the Problems Come From
Honey leaks and stains
UGA warns that combs may melt and stain interior walls with honey and wax. MAAREC adds that if honey soaks into walls, the stain can be impossible to paint or wallpaper over and may stay moist to the touch for a long time (MAAREC Publication 3.6). UF/IFAS notes stored honey can drip out near the nest and stain the wall or ceiling (UF/IFAS Extension IN771).
Pests drawn to old comb
MAAREC says honey and beeswax comb left behind will attract other insects and animals, and that comb can be attacked by wax moths. UF/IFAS notes pests feeding on remaining comb can get into the home.
New swarms
UGA notes that cavities that housed bees before tend to attract new swarms. See bees came back after removal?
What It Means During Removal
Because the comb is the problem, it has to come out. UF/IFAS calls complete comb removal essential and notes removers may need to cut into walls. For bees in structures, we use a thermal camera to find the comb, make a careful wall cutout, move the colony comb and all, and clean off leftover wax. Insulation that’s been soaked with honey or packed with comb usually has to be pulled out of that section too.
That’s also why killing bees in a wall makes things worse. UGA explains that if the colony dies, its combs are no longer ventilated by fanning bees, which is how comb ends up melting and leaking. See why beekeepers never exterminate honeybees.
What About Siding, Soffits and Brick?
The outside of the house usually shows less than the inside. Bees use an existing gap, such as a siding seam, a loose soffit panel or a mortar joint, rather than making their own. On a job in Wayne, we cut a 20-by-20-inch comb out from behind siding by hand and secured it into frames (The Mindful Beekeeper). The damage that matters is the opening needed to reach the comb, and what the comb and honey do if they’re left in place. See bees in a soffit and bees in a brick wall.
Warning Signs to Watch For
- Dark or amber stains on a wall or ceiling, especially below a known entrance.
- A sticky or soft spot in drywall.
- Bees flying in and out of one gap day after day. See honeybees in walls.
Frequently Asked Questions
What about bees in the chimney?
See bees in your chimney.
How much comb could be in there?
Can the wax be reused?
Beeswax is a valuable material. See MAAREC Publication 3.9 for how it’s made and used.
Seeing Stains or Bees?
Honeybees are always relocated, never exterminated. Rescued colonies go to The Mindful Beekeeper, pass through an inspection station, and then join Apiary #1 in Loudon Township. Honeybee relocation from walls and other structures is being scheduled for Spring 2027. Call or text 419-614-6445 or use our contact page to tell us what you are seeing, and read about humane honeybee removal and relocation.
