Swarms of mice are invading farms, homes, and businesses across southern and Western Australia this month [1, 2, 3].
The infestation threatens the region's agricultural productivity and creates significant public health risks for residents in affected communities [3].
Reports from May 2026 indicate that the plague has heavily impacted the town of Morawa in Western Australia [1, 3]. Residents and farmers are confronting thousands of mice swarming through farms [2]. These rodents have moved beyond the paddocks and are now entering residential bedrooms and local businesses [1].
Environmental conditions have created a surge in mouse populations, leading to widespread crop damage [2, 3]. The scale of the infestation has forced farmers to implement emergency measures to protect their livelihoods from the rodent surge [2].
Public health officials said they have concerns regarding the risks associated with such high concentrations of rodents in urban and rural settings [3]. The invasion of homes and businesses increases the likelihood of contamination and the spread of diseases associated with mouse infestations [3].
Local authorities and agricultural experts said they continue to monitor the spread of the plague as it moves through the southern and western regions of the continent [1]. The current surge is characterized by the sheer volume of mice, which have overwhelmed traditional pest control methods in several districts [2].

This mouse plague represents a significant ecological imbalance likely triggered by specific climatic conditions that boosted food availability and rodent breeding cycles. Beyond the immediate economic loss of damaged crops, the infiltration of residential areas in towns like Morawa necessitates a coordinated public health response to prevent zoonotic disease transmission.
