The short version
Track recurring bee activity with a simple log: date, time, temperature, location, number of bees and what they were doing. Scouts inspect a spot for minutes and leave; a colony shows a steady stream in and out. If the same spot draws bees on three or more warm days, or traffic grows from a few to dozens, the pattern has crossed from interest to occupancy and it is time to call a pro.
- Log date, time, temperature, spot, count and behavior for every sighting.
- Scouts visit and leave; residents come and go in a stream.
- Three visits to the same spot on warm days means the site is attractive.
- Carpenter bees return to the same wood every spring; log holes, not just bees.
- A dated log turns a vague complaint into a quotable job.
- Research: Roughly one Italian schoolchild in six reports swatting bees on sight, according to a 2024 study of 231 eighth-graders published in Insects, an international children's attitude that hints at why homeowners often overreact to a single foraging bee.
For homeowners, landlords and property managers who see bees at the same place on the house more than once and want to know whether it is scouts, foragers, a colony forming, or carpenter bees coming back. It works for honey bees, carpenter bees and bumble bees, and it is the record a pro will ask for.
What to look for
With a log, the second sighting at the same spot already stands out, and the decision to call is made on evidence rather than alarm. Without a log, the homeowner notices bees, forgets, notices again, and by the third time there is comb in the wall or a dozen new holes in the fascia. Both look like 'a few bees' at first, and both are cheaper to deal with early. Carpenter bees follow a yearly cycle, emerging from last year's galleries in spring and boring new ones nearby. Scouts find a cavity days before a swarm arrives, and once a colony has moved in, traffic builds over weeks. Honey bee colonies do not appear all at once.

Reading the pattern.
Three or more visits on warm days, low count, bees walking in and out: a site being seriously considered. Seal the gap when it is quiet if it leads into a cavity. One or two visits, low count, bees leaving: scouts or foragers. Look at the log by location and watch three things: frequency, count and behavior. What a pro will say when you send this: 'From your counts this went from scouts to a colony around May 9, so expect three to four weeks of comb.' That sentence is the difference between a rough guess and a real quote. Log the hole count, not just the bees, and plan treatment and painting. Large black bees hovering near wood, new round holes, sawdust: carpenter bees. promptly. Comb is building. Humming, warmth on the inside wall: established. Stop sealing plans and call a pro with the log. Rising count across entries, bees entering and staying, pollen on legs: occupied. Seal it now if empty, or expect a swarm to arrive.
Bees get in through gaps most of us never notice: a loose threshold, a siding seam, a soffit joint. A walk around the house with a flashlight finds most of them.After the call, keep logging.
During the visit, record what they found and compare it to your reading. The log does not stop when a pro is booked. If bees ever return, the file tells the next pro what happened, where, and when, and it turns a new investigation into a short visit to a known address. Keep the log with the company's proposal, photographs and invoice. New holes a foot away mean bare wood remains and needs sealing. Plugs that stay flush and painted with no new holes beside them mean the wood is now unattractive. For carpenter bees, add a yearly spring photo of each treated board. Bees drawn by residual scent will still test the site, and a few scouts leaving is normal; entries that show bees entering again mean the seal or cleanup failed, and the return-visit clause in your agreement applies. After a sealing, removal or treatment, log the same spot at two weeks, after the first hot spell and the following spring.
What affects the price
- Whether the site is still empty or already holds a colony.
- Number of gaps or holes to seal or plug.
- Height and access to the recurring spot.
- Species: honey bee sealing versus carpenter bee wood treatment.
- Whether old comb inside is drawing the scouts.
- Time of year, since spring bookings fill fastest.
When to call for help
Send the log with the request; it lets the pro decide whether to bring sealing materials or a cutout kit. regardless of the log if a swarm has clustered on the house and is walking into a gap, if bees are inside, or if someone in the household has a sting allergy. Call when the log shows the same spot drawing bees on three or more warm days, when the midday count rises between entries, when bees enter and do not return, or when you hear humming. For carpenter bees, call when the spring photo series shows new holes or sawdust near last year's.
What you can do yourself
So is sealing an empty gap once you are sure it is empty: a few warm days with no traffic, no humming and no warmth on the wall behind it. Keeping the log is your job, and it takes less time than worrying about it. And do not spray a recurring spot to 'discourage' bees; it does nothing for scouts and can violate state rules on honey bees. Do not plug carpenter bee holes while bees are still emerging in spring; wait, or let a pro time it. If they are living inside, sealing traps them and pushes them into the house. Do not seal a gap that bees are entering and leaving. Mesh and caulk on a gap that scouts keep visiting is one of the best prevention steps there is.
Simple ways to keep bees away
- Seal gaps at soffits, siding joints and vents before spring.
- Paint or seal bare wood on fascia, decks and rails.
- Remove old comb from any cavity that has held bees.
- Screen weep holes and attic vents with fine mesh.
- Walk the exterior weekly in April and May with the log.
- Keep the log going after a removal to catch a repeat.
After a removal, the old entrance gets screened and sealed. The smell of comb draws new scouts, so this step is what keeps bees from moving back in.Did you know?
Honey bee scouts dance to recruit others to a promising cavity.
Foragers with pollen on their legs are returning to a nest.
Carpenter bee males cannot sting; females rarely do.
Questions people ask
Why do bees keep coming back to the same spot on my house?
Scouts remember and recruit others. Logging the visits tells you whether it is still interest or has become occupancy, and sealing the spot while it is empty ends the cycle. Usually because the spot is attractive: a gap into a dry cavity, the scent of old comb, or bare wood for carpenter bees.
How do I tell scout bees from a colony?
A colony shows a steady stream in and out at midday, with bees carrying pollen on their legs. If you see pollen going in, bees are living there. Scouts arrive in ones and twos, walk around the gap, go in briefly and leave. Numbers rise and fall by the hour.
What should I write in a bee activity log?
Add a photograph when you can. Two lines per entry are enough; the value is in the dates and counts over time. Date, time, temperature, the exact location, how many bees, what they were doing, and your species guess.
Do carpenter bees come back every year?
Untreated wood accumulates holes year over year. A spring photo of the same fascia each year shows the growth clearly. Yes. New adults emerge from last year's galleries in spring, mate, and the females bore new tunnels, often in the same board.
Can I just seal the gap bees keep visiting?
Confirm by watching on a few warm days for traffic, listening for humming and feeling for warmth on the inside wall. If bees are entering and leaving, do not seal; call a pro, because there is a colony inside. If it is empty, yes, and it is a good idea.
When is recurring bee activity an emergency?
When a swarm is clustered on the house and entering a gap, when bees are inside living space, or when anyone at home has a sting allergy. In those cases call the same day rather than waiting for the log to fill in.
How much does it cost to remove Africanized honeybees?
Keep people and pets well away from the colony, and call a licensed professional rather than attempting removal, since these bees pursue perceived threats much farther than ordinary honeybees. Treat it as a rough guide, not a local count. HomeAdvisor's 2026 pricing benchmarks estimate Africanized-honeybee removal at $100 to $1,000, starting higher than standard honeybee removal because the colonies defend themselves aggressively and require protective gear and extra care.
How much does live bee relocation cost?
Live removal takes longer than extermination. Ask the pro how they handle the comb and honey left behind, which otherwise draws ants and rodents. 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.
