Repairs & Maintenance - Pest Control
The Act says that the lessor, agent or provider must maintain the premises in good repair and in a state fit for you to live in.
You must keep the place clean and not damage the premises. If you follow your responsibilities under the Act and do not cause a pest problem (e.g. by keeping a pet on the premises), then, regardless of what is written in your agreement, your lessor, agent or provider will be responsible for pest control.
If you have a pet in the premises during the tenancy, you will need to do pest control or have professional pest control carried out. Keep any receipts as evidence. If there is a dispute about pest control, these documents can show that you have taken reasonable steps to reduce any pest control problem.
