Saturday morning: a message arrives about cockroaches on the third floor. An hour later another resident mentions a mouse near the bins, and in the evening a third asks about a snake in the car park. Complaints about pests combine the technical and the social. The manager has to reassure residents, find the source, share the cost fairly and leave a clear record. This playbook goes from the first message to the decision.
Step one: capture the complaint properly
A vague message such as “there are bugs” gives you nothing to act on. A short form, filled in by the resident or by you over the phone, solves that.
| Field | Example |
|---|---|
| Date and time | 12 June, about 10.30 pm |
| Location | Block B, third floor, kitchen |
| What was seen | Small brown insect, runs fast |
| Photograph | Attached if possible |
| How many | One or two / five to ten / too many to count |
| Seen before? | First time / third time |
| What was done | Nothing / swept up |
The simpler the form, the more likely it will be used. What matters is that each complaint becomes dated, searchable information.
Step two: flat, building or both?
Deciding the scope is the hinge of the whole process.
- One flat, one sign: probably a matter inside the flat. The resident reviews food storage and tidiness and the manager gives advice.
- Several flats with the same sign: points to a shared source such as a pipe riser, a bin room or the roof.
- Ground and garden complaints: bins, car parks, gardens and drains normally fall under shared areas.
- Signs moving floor to floor: suggests vertical voids and pipework.
A simple sketch of the building with a marked dot for each complaint turns scattered messages into a pattern. If flats stacked on one riser report in sequence, look there first.
Step three: what is it?
Residents say “bugs”, but the manager needs to know what kind, as the response depends on it. Ask for a close photo with a coin beside it. For a first idea, our guide to ants in the house and the article on telling rats from mice are useful. Do not argue about species in notices to residents; leave identification to the evidence.
What good practice says
The US Environmental Protection Agency’s pest control resources for housing managers is aimed at American housing but its principles travel well. It advises regular inspections of the building exterior to spot holes where pests may enter, notifying residents of a pest professional’s visit in advance, setting up a reporting system for residents and staff, and documenting observations. It adds that common areas, especially rubbish chutes and skips, should be kept clean, that broken windows, screens, vent covers and holes in exterior walls should be fixed as soon as possible, that gaps around plumbing and wiring should be sealed, and that leaks should be repaired. It also says management remains responsible for the programme, and that effective schemes in multi-family housing need residents as part of the team.
A notice to residents
Dear residents, some flats have recently reported pests. To find the source we will inspect the building’s shared areas. If you see anything, please send the date, location and, if possible, a photograph to the management office. Please also tie rubbish bags and put them in the bins promptly.
Leave out blame, such as which flat is “responsible”, and promises about results. The sentence about what residents should do next is the most valuable one.
Who does what
- Manager: logs the complaint, defines its scope, checks shared areas, arranges an assessment if needed and reports back.
- Resident: keeps their own food and waste in order, reports sightings and allows access.
- Caretaker or gardener: keeps bin lids closed, empties them on schedule and tidies surroundings.
Keep a complaints log
A single spreadsheet is enough: date, location, pest, photograph, action and outcome. At the end of each month, summarise it. You may notice ants in late spring, mosquitoes in summer and rodents in autumn, so you can plan ahead. In meetings, a log lets the board decide on facts instead of impressions.
Awkward situations
Every block has a resident who never reports and one who reports everything. The first may hide a source that grows unseen, and the second may be right more often than you think. Ask both the same questions: what did you see, where and when? Talk about evidence, not personalities.
Another common obstacle is a flat that cannot be entered. If the source is probably there and the door stays shut, the building assessment is incomplete. Politely inform the resident, suggest a time and, if necessary, refer to the management rules. This article offers no legal opinion; rely on your management plan and legal adviser.
Questions for a contractor
- What authorisations does the firm hold, and where are they listed?
- What will the first visit cover, including shared areas?
- What do residents need to do before and afterwards, and when can they use the area again?
- How are results reported, and what happens if complaints return?
- What paperwork will the management receive?
Request written answers and file them. These questions are not meant to bargain but to make the process clear.
Season by season
Complaint types shift through the year. Ants and flies appear in late spring, mosquitoes and cockroaches in early summer, wasps and garden insects in late summer, and mice and spiders as autumn begins. Putting the calendar on the board agenda lets you check bin rooms, gardens, pipe shafts and roofs before trouble starts. Our piece on mosquito prevention in gardens is a good example of a shared-garden checklist.
Cost and communication
Who pays for work in shared areas is a matter for your management rules, and this article does not give a legal view. Record decisions in the board minutes and tell residents in writing. Openness saves arguments at later meetings.
When the board needs outside help
When complaints keep coming from several flats, a shared pipe riser or bin room is suspected, and your own observations cannot find the source, an on-site assessment is the sensible step. You can read about our work for residential complexes and apartment buildings, and request a free inspection through the contact page. Having your complaint log and a sketch of the building ready makes the first conversation short and productive.
