Bees in a Brick Wall: Honeybee Colonies in Older Brick and Stone Homes

/in /by

Many homes and farm buildings across our area are brick or stone, some of them well over a century old. When you find bees in a brick wall, they’re usually using a worn mortar joint or a gap around a window or vent as the doorway to a cavity behind. Here’s why older masonry can host a colony for years, why you shouldn’t seal it, and how we plan a removal.

Why Bees in a Brick Wall Can Stay for Years

Honeybees look for a dry, enclosed cavity with a small entrance. Research on nest-site selection found swarms prefer a cavity of roughly 40 liters with a small entrance near the bottom, and that they favor cavities used before (Seeley and Morse, 1978). An old wall with voids between the brick and the interior can offer that. UGA Extension notes bees can live in a structure indefinitely, and a cavity that once held bees attracts new swarms (UGA Extension C824). In other words, an old wall can be reused colony after colony.

Signs to Look For

  • Bees flying in and out of one mortar joint or gap, day after day.
  • A hum behind interior plaster or drywall on warm afternoons.
  • Stains or a sticky spot on the inside of the wall. See can bees damage your house?

A worn mortar joint can lead to a cavity behind the brick.

Why Not to Patch the Mortar First

It’s tempting to repoint the joint and be done. But sealing traps the colony inside, and the bees may look for another way out, sometimes into the house. MAAREC warns that comb and honey left in a wall attract pests and can soak in and stain (MAAREC Publication 3.6). UF/IFAS calls complete comb removal essential (UF/IFAS IN771).

How a Masonry Removal Is Planned

Every brick or stone wall is built differently, so there’s no one method. We start with photos and a thermal camera scan to find where the warm comb sits. Then we talk through how to reach it, which might be from the inside wall rather than through the masonry, and what repair will look like afterward. On a September 2025 job at an 1800s church in Rudolph, the thermal camera located the colony in two wall channels beneath a window (The Mindful Beekeeper).

Once the comb is out and the cavity is cleaned, the gap can be properly sealed. See bees came back after removal?

Bees in the House: How Honeybees Get Indoors and What to Do

/in /by

Finding bees in the house is unsettling, but what it means depends on how many you see and where. One or two honeybees at a window usually wandered in by accident. A few new bees every day near the same light fixture, outlet or vent is a different story. That pattern often points to a colony living in the wall or ceiling right next to you.

Bees in the House: What the Pattern Tells You

A few bees at a window

Bees that get indoors fly toward the light. WSU Extension notes that bees trapped indoors fly to windows trying to escape (WSU Extension). A bee or two that came in through an open door is no cause for alarm.

New bees every day near a fixture or vent

If bees keep appearing near a ceiling light, a recessed can, an outlet, a fan or an attic hatch, they may be coming from a colony in the cavity behind it. Gaps around fixtures give them a path into the room, and the light draws them out. Look outside for bees flying in and out of a gap in the siding, soffit or chimney on the same side of the house. See honeybees in walls and bees in your chimney.

Bees showing up near a ceiling light, day after day, can mean a colony in the ceiling or wall.

Bees indoors after the entrance was sealed

Sealing the outside entrance traps the colony. The bees may look for another way out, sometimes into the house. That’s one of the main reasons we ask people not to seal or spray before removal.

How Bees Get Indoors in the First Place

The colony itself is usually outside the living space, inside a wall, ceiling or chimney. UGA Extension notes that bees flying back and forth from a gap in the walls of a house is a sign a colony has set up inside the hollow, and it advises caulking likely entry points such as knotholes, siding gaps and openings around plumbing and wires. The same kinds of gaps on the inside, around fixtures, vents and trim, are how a few bees end up in a room.

What to Do Right Now

  • Catch and release a stray. WSU suggests trapping a bee in a glass or jar against the window, sliding a card underneath, and releasing it outdoors.
  • Close off the room if bees keep appearing from one fixture, and keep pets out.
  • Don’t remove the fixture or spray into the gap. Note where they’re coming from.
  • Look for stains on the ceiling or wall nearby. See can bees damage your house?

Frequently Asked Questions

Are they honeybees or wasps?

In fall and winter, wasps indoors are common too. See wasps inside your house and honeybee vs. yellowjacket.

Why are bees showing up in winter?

A colony in a warm wall stays active through winter, clustered around the queen. On mild days, or near a warm fixture, some bees may wander toward the light. A steady trickle in winter is a strong sign of a colony.

What about the soffit or porch ceiling?

Bees Came Back After Removal? Why It Happens and How to Prevent It

/in /by

The colony is gone, the wall is patched, and then a few weeks or a year later, bees are back at the same spot. If your bees came back after removal, you’re not alone, and it usually has a clear cause. Either something was left behind, or the cavity is still open and still attractive to swarms. Here’s why it happens and how to stop it.

Why Bees Came Back After Removal

1. Stragglers the next day

A few bees hovering the morning after isn’t a return. UGA Extension notes stray workers may be around after a removal and are usually gone within a day (UGA Extension C824). UF/IFAS notes a swarm trap or sticky trap can be left for up to a month to catch stragglers and returning bees (UF/IFAS Extension IN771).

2. Comb or honey left in the wall

UF/IFAS calls complete comb removal essential. MAAREC says leftover honey and comb attract other insects and animals (MAAREC Publication 3.6). If a previous company sprayed but left the comb, that’s often the source of the problem.

3. A cavity that bees like

Research on nest-site choice found that swarms prefer cavities that were used before (Seeley and Morse, 1978). UGA says the same thing: cavities that housed bees attract new swarms.

Sealing gaps around pipes and wires, after the comb is gone, helps keep new swarms out.

How to Prevent It

  • Get all the comb out first. Sealing before the comb is gone traps the problem inside.
  • Clean the cavity. We clean off leftover wax so new swarms aren’t drawn back.
  • Wash the entry. MAAREC recommends washing the entry area with soapy water, then filling the cavity and blocking the entrance.
  • Seal the gaps. UGA advises caulking likely entry sites such as knotholes, gaps in siding and openings around plumbing or electric wires.
  • Watch in swarm season. Spring and early summer is when scouts are out looking. A few bees investigating one spot is the early warning.

Frequently Asked Questions

Is one or two bees at the gap a problem?

Not necessarily. Foragers may visit nearby flowers or water. Bees that keep investigating one particular gap, rather than passing by, may be scouts. If the number climbs, call before a swarm moves in.

When is the best time to seal?

After every piece of comb is out and the cavity is cleaned, and ideally before the next spring swarm season.

Should I spray the spot to keep them away?

Spraying doesn’t remove scent or comb, and it can contaminate bees that would otherwise be rescued. Seal the gap instead.

Could it be wasps this time?

Wasps reuse sheltered spots too. See wasp-proofing your home and after wasp nest removal.

How do I know it’s a new colony?

Steady traffic for more than a day or two means bees are moving in. See will bees leave on their own?

Bees Back at the Same Spot?

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.

Can Bees Damage Your House? Wax, Honey Leaks and Stains

/in /by

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?

An opened wall cavity. Colonies often build comb in spaces like this, between studs.

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.

How Many Bees in a Hive? What a Wall Colony Really Holds

/in /by

When we open a wall, people are always surprised by the number. So how many bees in a hive? According to MAAREC, a colony is made up of thousands of workers, and as it grows it can reach a maximum of about 60,000 workers. In late spring and summer there’s also a single queen and several hundred drones. A colony in your wall works the same way as one in a beekeeper’s box.

How Many Bees in a Hive, Season by Season

Spring and early summer: growing fast

MAAREC notes that queens lay the most eggs in spring and early summer, up to about 1,500 eggs a day at peak. That’s when colonies grow fastest and when swarms leave to start new colonies.

Summer: peak population

The University of Arkansas Cooperative Extension notes that workers reared in spring and early summer live about five to six weeks, so the colony is constantly replacing itself. A strong summer colony is at or near its largest.

Fall and winter: fewer bees, more honey

Colonies shrink going into winter. The bees cluster around the queen to keep her warm. UF/IFAS Extension IN1006 says a colony in the North generally needs about 90 pounds of honey reserves to get through winter, because bees can’t forage then.

A single sheet of comb can be covered in thousands of workers in summer.

What That Number Means for Removal

  • More bees means more comb. Workers produce the wax and build the honeycomb, the University of Arkansas notes. A large colony has built a lot of it.
  • More comb means more honey in the wall. MAAREC warns that comb left behind attracts pests and that honey can soak into walls and stain them (MAAREC Publication 3.6).
  • Killing them doesn’t remove any of it. See can bees damage your house?

For scale, our July 2025 grain bin rescue in Fostoria involved seven layers of comb and more than 20,000 bees relocated alive (The Mindful Beekeeper).

Frequently Asked Questions

Do all those bees fly out at once?

No. The University of Arkansas notes that a worker spends roughly its first two weeks as a house bee, working inside the hive. Only part of the colony is out foraging at any moment, which is why a busy entrance can still badly understate what’s inside the wall.

What do the drones do?

Drones are males. The University of Arkansas notes they don’t tend brood, make wax or collect pollen or nectar. They’re reared mainly in spring and summer to mate with new queens.

How many bees are in a swarm?

MAAREC says a swarm contains thousands of workers and their queen. See honeybee swarms.

How big is a bumblebee colony?

Much smaller. See bumblebee nest in the ground.

What’s inside the comb?

See inside a wild honeybee nest.

Bees in a Soffit or Porch Ceiling: What You’ll See and What Happens Next

/in /by

A steady stream of bees going in and out of a corner of your roofline is hard to miss. Bees in a soffit or porch ceiling are usually honeybees that have moved into the dry, sheltered space inside the overhang. MAAREC notes that honeybees nest in sheltered, dark enclosures, including porch roofs and spaces between wall studs (MAAREC Publication 3.6). Here is what you’ll see, what not to do, and how a live removal from an overhang works.

Signs of Bees in a Soffit

  • Same gap, every day. Bees flying in and out of one opening for more than a day or two point to a colony, not a passing swarm. See will bees leave on their own?
  • A hum overhead. On warm afternoons you may hear it through the porch ceiling.
  • Stains or drips. Dark staining, wax or honey seeping from boards is a sign of comb above.
  • Bees near porch lights or indoors. See bees in the house.

Honeybees or Wasps?

Wasps love soffits too. Honeybees are fuzzy and brown to amber, and fly in a steady line. Yellowjackets are smooth, shiny and bright yellow and black. If it’s wasps, see wasps in your attic or soffit and honeybee vs. yellowjacket.

Gaps in porch ceiling boards and around fixtures can lead into the cavity above.

Why Overhangs Attract Colonies

Research on how swarms pick a home found that scouts prefer an enclosed cavity of roughly 40 liters with a small entrance, several meters off the ground (Seeley and Morse, 1978). A boxed-in soffit or the space above a porch ceiling can match that closely. UGA advises caulking likely entry points such as gaps in siding and openings around plumbing or wires, which applies to loose soffit panels and fixture gaps too.

Why You Shouldn’t Seal the Entrance

Sealing the gap traps the colony. The bees may look for another way out, sometimes into the house. Even if the colony dies, UGA warns that comb can melt and stain interior walls with honey and wax (UGA Extension C824). The comb has to come out.

How a Live Cutout From an Overhang Works

  • Find the comb. A thermal camera shows where the warm comb sits in the overhang.
  • Open the soffit or ceiling. We remove panels or boards carefully to reach the colony.
  • Move the colony comb and all. Comb with brood is secured so the colony keeps it.
  • Clean the cavity. Leftover wax is cleaned off so new swarms aren’t drawn back. See bees came back after removal?

The bees go to The Mindful Beekeeper, through an inspection station, and into Apiary #1 in Loudon Township.

Frequently Asked Questions

Can they stay?

UGA suggests a leave-alone approach can work when the entrance is high and far from people and pets, like a roof peak. A porch ceiling over the front door usually isn’t that spot.

Is the porch light part of the problem?

Gaps around a fixture can be an entry point into the ceiling cavity. Don’t remove a fixture with bees behind it yourself. Tell us where it is so we can plan around the wiring.

How do I get ready?

See preparing for bee removal.

Myth: Will Bees Leave on Their Own if You Wait? Swarms vs. Wall Colonies

/in /by

“Just wait, they’ll leave.” It’s the most common advice people get about bees, and it’s half right. The answer to will bees leave on their own depends on whether you’re looking at a swarm or a colony. A swarm is a temporary cluster that usually moves on. A colony that has already moved into your wall, soffit or chimney has found its home and is building comb. Waiting usually means a bigger colony and more comb to remove later.

Will Bees Leave on Their Own? Swarms Usually Do

When a colony reproduces, part of it leaves with a queen and clusters in a temporary spot while scouts search for a new home. UGA Extension describes swarms as often basketball-sized, gentle, and usually relocating within about 24 hours (UGA Extension C824). Our own experience matches: a swarm often moves on within a day or two.

MAAREC notes that swarming bees are generally gentle because their stomachs are full of honey (MAAREC Publication 3.6). That doesn’t make it safe to poke at one, but it does mean a swarm on a branch is rarely an emergency.

Cluster of honeybees hanging from a tree branch, the kind of swarm where the answer to will bees leave on their own is usually yes
A hanging swarm is a temporary stop while scout bees look for a permanent home.

Established Colonies Don’t Leave

Once bees move into a cavity, they build wax comb, the queen begins laying, and the colony stores honey. UGA notes that bees can live in a structure indefinitely, and a cavity that once housed bees tends to attract new swarms. Signs you have a colony rather than a swarm:

  • Bees fly in and out of the same gap day after day, through more than a day or two.
  • You hear a hum in the wall on warm afternoons.
  • Dark staining, wax or honey appears near the entrance.

See honeybees in walls and bees in your chimney.

When Leaving Them Alone Can Work

UGA Extension notes that the natural nest site of honeybees is a hollow in an old tree, and that if a colony’s entrance is far from people and pets, such as near the peak of a roof, a leave-alone approach is worth considering. If the flyway is near a door, a walkway or a play area, it’s a more serious situation. Either way, the bees aren’t going to pack up on their own. See bees in a tree.

Why Waiting Can Make It Worse

A colony keeps building comb. MAAREC warns that comb left in a wall can attract pests and that honey can soak into walls and stain them. Killing the bees doesn’t solve that either. The comb has to come out. See why beekeepers never exterminate honeybees.

Frequently Asked Questions

How long can a colony stay in a wall?

UGA notes that bees can live in a structure indefinitely. Colonies grow through spring and summer, so the longer you wait, the more comb there usually is. See how many bees in a hive.

Can I just seal the hole?

No. Sealing traps the colony, and the bees may find another way out, sometimes into the house.

Is swarm removal free?

Exposed swarm removal is free through The Mindful Beekeeper. See honeybee swarms.

Is it a swarm of bees or wasps?

See swarm of bees or wasps? for a quick ID guide.

Not Sure Which You Have?
