APARTMENT PEST CARE
Cockroaches in apartments: what residents should record
In a multi-unit building, a clear record is more useful than a vague report of “cockroaches everywhere”. Location, timing and photos help show whether the activity appears isolated or connected to shared areas.
Cockroaches can arrive with boxes or appliances, live inside one unit, or move through service areas. A photo and a simple sighting log help avoid assumptions about the species, source or responsibility.
What should you record?
- The date and approximate time of each sighting.
- The exact room and location: sink, cupboard hinge, appliance, hallway or bin room.
- Approximate size, colour and whether the insect had visible wings or stripes.
- A clear photo or short video when it is safe to take one.
- Whether activity is during the day, at night or in several rooms.
- Counts and locations from labelled sticky monitoring traps.
Keep the log for 7–14 days if the activity is limited. Repeated daytime sightings, many small cockroaches or activity in several rooms deserve earlier attention.
Do this in your apartment today
- Seal food and pet food; clean crumbs, grease and spills.
- Dry sinks overnight and report leaking taps or pipework.
- Empty rubbish and recycling; rinse containers before storage.
- Reduce cardboard and clutter around the kitchen and laundry.
- Check delivered boxes and second-hand appliances before bringing them inside.
Cleaning supports control but does not prove who caused the problem. Apartment activity may involve an individual unit, shared service routes or more than one source.
How to report the problem clearly
Send the property or strata manager the dates, locations and photos, plus any relevant plumbing or building defect. Ask whether similar activity has been reported in nearby units or common areas and whether a coordinated inspection is being arranged.
If you rent, keep copies of your written report and follow-up. This article does not determine who must pay or arrange treatment; that depends on the circumstances, the property and current tenancy or strata requirements.
If common areas need treatment
NSW EPA guidance says residents of multiple-occupancy residential complexes must generally receive at least five working days' notice before pesticides are applied in common areas. The notice should identify what will be used, why and where it will be applied, the date, any label re-entry requirements and contact details. Defined pest emergencies are treated differently.
The organiser and pest management technician have specific notification duties. Residents can also request the relevant safety data sheet. For current details, see the NSW EPA common-area notification guidance.
Get professional help if
- Activity continues after 7–14 days of cleaning, moisture control and monitoring.
- You see cockroaches during the day, in several rooms or inside appliances.
- Several apartments or shared areas appear affected.
- Children, pets, pregnancy, asthma, allergies or food areas make treatment planning more sensitive.
Avoid homemade pesticide mixtures and off-label use.
Avoid making foggers or broad spraying the default response.
Do not spray over or beside professional bait placements.
MAKE THE REPORT USEFUL
Send the sighting details.
Text your suburb, apartment level, where and when you saw activity, and a clear photo if available.
