Rodents are one of the most frequently reported issues in suburbs such as Midland, Swan View, Guildford, and Aveley. Their behaviour is strongly linked to temperature changes and available food sources.

Because the City of Swan includes bushland, rural edges, wetlands, older suburbs, and new estates, seasonal pest activity can vary widely. Knowing what to expect each season helps residents stay ahead of potential infestations.

The City of Swan has a unique mix of wetlands, riverside pockets, and warm summer weather — the perfect combination for mosquitoes to breed. Areas near the Swan River, Jane Brook, and residential lakes in Ellenbrook and Aveley can experience higher mosquito numbers at certain times of the year.
