The short version
Coordinate a multi-unit bee inspection by treating the building as one structure: map every reported sighting on a single plan, give residents written notice with access windows, walk the exterior with the pro first, then inspect only the units adjacent to confirmed entrances. Record findings on one sheet so a single scope and quote covers the whole building rather than a series of unit-by-unit visits.
- Bees in a shared wall belong to the building, not to the unit that reported them.
- Map every sighting on one plan before scheduling any inspection.
- Exterior walkthrough first; interior unit access only where entrances are confirmed.
- Give residents written notice with a date, time window and what to expect.
- One consolidated findings sheet produces one scope and one quote.
- Research: In a 2024 study of 231 eighth-graders in Sicily, Italy, published in the journal Insects, 17.8% of students, combining agree and strongly agree responses, viewed honeybees as the most aggressive insects.
For property managers, HOA boards, landlords with several units and maintenance supervisors organizing a bee inspection across a building or complex. It covers honey bee colonies in shared walls and soffits, carpenter bees along shared decks and fascia, and the notice and access steps for both.
What to look for
In a single-family house, the homeowner watches the wall, calls a pro, and opens the door. In a building, the sighting comes from one resident, the entrance is above another's balcony, the comb runs behind a third's closet, and the manager has to arrange access to all of them. Pros who arrive to inspect one unit often find nothing, because the colony is two bays over, and the visit is billed anyway. Carpenter bees create a smaller version of the same problem along a shared fascia or deck rail: each resident reports the three holes they can see, no one sees the forty in total, and the treatment gets quoted three times. A single map and one coordinated inspection fixes both.
- 1Several units reporting bees or humming in the same stack.
- 2Bees entering a soffit, vent or siding gap on one elevation.
- 3Bees indoors in a top-floor unit with no open windows.
- 4Stains or warm patches on a shared wall or ceiling.
- 5Round holes and sawdust along a shared fascia or deck.
- 6Bees at a common-area dumpster, pool or landscape bed.
Why it’s worth acting soon
- A colony spanning two floors grows into a much larger cleanup.
- Sting incidents near entries and balconies raise liability.
- Repeated single-unit inspection fees add up with no result.
- Residents block or spray the entrance and drive bees inside.

A honey bee colony in the attic often announces itself with a hum on warm afternoons. Unscreened vents like this one are a common way in.Coordination checklist, start to finish.
5. Issue resident notices for the units in the suspected stack, with a time window and a plain description of what will happen. 6. Walk with the pro. Confirm and photograph each entrance. 7. Enter only the units adjacent to confirmed entrances. Record thermal findings per unit. 8. Request a consolidated findings report and a single quote. 9. Circulate the report to the board or owner and schedule the removal with a second notice. 10. Add the report, map and photographs to the building bee file. Each step is short. The order is what saves the money. 1. Collect every report. Unit, date, what was seen or heard, where in the unit. Ask each resident for a photograph if they have one. 2. Map them. Mark each report on a floor plan and on an elevation sketch. Note the stack (units sharing a wall vertically). 3. Do a first exterior look. Staff walk each elevation at midday for ten minutes watching soffits, vents and siding gaps. 4. Book the pro for an exterior walkthrough and say which elevation you suspect.
What to record and what a good answer sounds like.
Good: 'Exterior lift for the soffit, and 2B's closet wall opened from inside. Write the answers on the findings sheet. A pro who answers this way can quote one job. A pro who cannot will quote several. On the sighting log, record specifics: 'Unit 3B, May 4, humming behind bedroom closet wall, north side, louder evenings.' On the map, use one symbol for reports and another for confirmed entrances. During the walkthrough, ask the pro three questions. Where is the entrance and are there others? Good: 'Main entrance at the soffit joint above 2B's balcony, a second at the dryer vent on 1B. Both go into the same bay.' Vague: 'They are all over the north side.' How far does the comb extend? Good: 'Thermal shows warmth from the top plate of 2B down to about waist height in 1B, one bay wide.' Vague: 'Could be a lot.' What access will you need for removal?
Fall is the easiest time to seal gaps along the foundation and siding, once bee traffic has slowed and before next spring's scouts start looking.From findings to one scope.
After the job, add the invoice, the company's photographs and the sealing map to the building file. Next spring, walk the same elevation during swarm season. A building that has hosted one colony is a known address to the next swarm, and the sealing map tells staff exactly where to look. The consolidated report should let a board or owner make one decision. Check it for: each entrance with a photograph, the affected units by number, species, comb extent, the recommended method and why, the access plan, the repair the building will face, and the resident notice the removal will need. Then request a single quote against that report, itemized into removal, comb cleanup, sealing, repair and return visits. Ask that sealing cover every entrance found, not only the main one, and that the quote say which units must be entered on the removal day and for how long. Send the second resident notice with the removal date, the units affected, the time window, and practical guidance: close windows, keep pets away, expect noise from the wall opening.
What affects the price
- Number of elevations and stories to walk.
- Number of units requiring interior access.
- Height and whether a lift is needed for soffits.
- Whether the inspection fee is credited toward the removal.
- Extent of the colony across floors, which sets the removal scope.
- Carpenter bee hole count along shared wood.
When to call for help
immediately, ahead of the mapping step, if bees are inside a unit in numbers, if a resident reports a sting allergy, or if the colony is near a pool, playground or main entry. In those cases the pro can secure the area first and the coordinated inspection follows. Engage a pro as soon as two reports land in the same stack, or one report includes bees indoors, humming in a wall, or a visible stream at the exterior. Ask for an exterior walkthrough first and say you will arrange unit access only where they confirm an entrance. Pros experienced with buildings will expect this and will bring a thermal camera.
What you can do yourself
Let the pro do that part, and give them the map so they spend their time on the right wall rather than the right building. Confirming comb extent behind a shared wall takes a thermal camera and experience reading it. Sealing an active honey bee entrance pushes bees into the nearest unit through outlets and trim. What staff should not do is open walls, spray entrances or block holes. Maintenance staff can also do the first exterior walk to confirm which elevation has traffic, which narrows the company's visit. The mapping, notices and access scheduling are management tasks and should be done in house; a pro cannot do them for you and will charge for waiting time if they are not done.
Simple ways to keep bees away
- Add bee sightings to the maintenance ticket system with unit and location.
- Walk soffits and fascia each spring before swarm season.
- Seal siding gaps, vents and weep holes with mesh across all elevations.
- Paint or seal bare wood on shared decks and fascia.
- Keep one building bee file with maps, reports and past removals.
- Tell residents in the spring notice how to report bees and what not to do.
Before you call, jot down where the bees go in, how long you've noticed them and whether anyone at home has a sting allergy. That is enough to get a useful answer.Did you know?
A honey bee colony can extend through more than one floor of a stud bay.
Swarm season in most of the United States runs from spring into early summer.
Bees drawn to a dumpster are usually foragers, not a nesting colony.
Questions people ask
Who is responsible for bees in a shared wall of a condo or apartment?
Check the governing documents and leases; some assign interior finish repair to the unit owner. Either way, coordination is a management task. In most buildings the exterior envelope and shared walls belong to the association or owner, so inspection and removal are a building cost.
How much notice do I have to give residents for a bee inspection?
Bees inside a unit or a sting-allergy report may qualify as an emergency under many leases. Give written notice with the date, time window and purpose, and keep a copy. It varies by state and by lease, commonly 24 to 48 hours for non-emergency entry.
Do we need to inspect every unit?
Walk the exterior first to find the entrance, then inspect only the units sharing the wall or ceiling near it, usually two to four. Inspecting every unit costs more and rarely finds anything the exterior did not point to. No.
What should the findings report include?
Each confirmed entrance with a photograph, the units affected, the species, an estimate of comb extent, the recommended method, the access needed for removal, and any repair the building will face. One document for the whole building, not a note per unit.
How do we handle carpenter bees along a shared deck or fascia?
Quote the treatment and plugging as one job. Ask the pro whether painting bare wood is included, and schedule plugging after emergence so the galleries are not sealed with bees inside. Have one person walk the full length and count holes with locations.
What do we tell residents while we wait for the inspection?
Keep windows near the site closed, do not spray or block the entrance, keep children and pets away from the area, and report any bees indoors immediately. Give the date of the inspection and say that no product will be applied during it.
How much does live bee relocation cost?
Ask the pro how they handle the comb and honey left behind, which otherwise draws ants and rodents. Treat it as a rough guide, not a local count. HomeAdvisor's 2026 pricing benchmarks estimate paid live bee relocation at $100 to $800, with the top of the range covering colonies that have to be cut out of a wall or roof and moved intact. Live removal takes longer than extermination.
How much does carpenter bee treatment cost?
Budget separately for plugging holes and painting or sealing bare wood, which is the main way to discourage the bees from returning. It's a published estimate, not a local quote. HomeAdvisor's 2026 pricing benchmarks estimate carpenter-bee treatment at $75 to $500, depending on how many nesting holes there are and how accessible they are. Treatment does not undo the tunneling.
