The most common pests in Wanaka are mice and spiders. Mice often make their way into homes when the weather gets cooler. Spiders can be a problem and many people are fearful of white tail spiders.
Assuming the tenant is not living in a way which encourages pests and the owner has not caused the infestation either, then in many cases the tenants and owner agree to split the cost as there is no legal precedent as to who pays.
We get a number of requests each year for houses to be sprayed for spiders and / or flies. It is not cheap but to be most effective both outside and inside need to be sprayed.
Mice can really damage a house if left untreated. They chew wires / doors / walls and are unhygienic . It is definitely in the owner’s interests to deal with a mouse or rat problem as soon as it occurs. A simple mouse trap can work if the tenants are willing to bait and clear them. However, mice can be very persistent and in our experience are best dealt with by professionals who will put down bait stations.
