The strata pest challenge
Strata and multi-unit properties face pest challenges that single homes don't. Pests don't recognise unit boundaries — cockroaches, bed bugs and rodents travel between units through shared wall cavities, plumbing and ventilation. A pest problem in one unit can quickly become a building-wide issue. Effective strata pest management requires a coordinated approach covering individual units, common areas and the building structure.
Common strata pest problems
- Cockroaches — spread between units through shared plumbing and wall cavities
- Bed bugs — introduced by tenants via travel; spread between adjacent units
- Rodents — travel between units via wall cavities, subfloors and roof voids
- Termites — can affect the entire building structure, not just one unit
- Ants — trail between units through shared wall spaces
- Birds and possums — nest in shared roof voids and common areas
Building a strata pest management plan
- 1Schedule regular inspections of common areas — foyers, hallways, garbage rooms, car parks, plant rooms and external areas
- 2Coordinate termite inspections and management for the building structure — this is a strata responsibility, not an individual owner's
- 3Establish a response protocol for tenant pest reports — including who is responsible (owner, tenant or strata) for different pest types
- 4Implement preventative treatments in high-risk common areas — garbage rooms, drainage areas, plant rooms
- 5Maintain documentation for all pest control activities — important for compliance and dispute resolution
- 6Communicate with tenants about pest prevention — clean kitchens, reporting sightings promptly, not introducing pests via second-hand furniture
- 7Address building-wide issues — sealing gaps, repairing screens, maintaining garbage area hygiene
Who is responsible for what?
In NSW strata schemes, pest control responsibility is generally divided: strata is responsible for common property and the building structure (including termite management of the structure); lot owners are responsible for pests within their unit (cockroaches, ants, bed bugs); tenants may be responsible for pest control at the end of a lease under some tenancy agreements. However, when pests originate from or travel through common property, strata responsibility may extend. Clear documentation and a defined response protocol prevent disputes.
Termite management for the building structure is a strata responsibility under the Strata Schemes Management Act. Failure to maintain termite protection can result in strata liability for structural damage. Annual termite inspections of the building are essential.
