Living with decaying bodies: This is the biggest nightmare of Australian farmers

Can you imagine walking into a house full of decaying bodies and a soul-wrecking smell? Well, this is what thousands of farmers in Australia are calling to be their worst nightmare. Recently, thousands of Australian grain farmers are struggling

in an exhausting battle against a massive mouse plague that is threatening their livelihoods, invading their homes, destroying their newly planted crops and wreaking havoc on their farms. What happened and how the Australians are being forced to live with decaying bodies, toxins and the nauseating smell of mice. Read on to know more….

What really happened?
There’s no denying that the world is going through a tough phase amidst the ongoing conflict in the Middle East, which has severely disrupted global supply chains, leading to a surge in the cost of vital farming inputs like diesel, fertilizers, etc. However, the rising mouse plague threat crisis hits at a time when the agricultural sector is already under intense strain. Now, farmers are forced to spend hundreds of thousands of dollars on buying rodent poison or entirely replanting their fields to get rid of this sudden crisis.

The real condition
Speaking to the BBC, Geoff Cosgrove, 43, who manages a 14,000-hectare property in Mingenew, Western Australia (WA) expressed that "It’s a massive financial hit, and it’s not just about the cost of the bait." He further added that his farms produce vital export and domestic crops, including wheat, canola, lupin, and barley.
Beyond the financial ruin and rodent-created crisis, Cosgrove shares the severe psychological toll. "They really mess with your head. You hear them running around at night in the ceilings and the air conditioning units. And the smell—it's like a decaying body." He further went on to mention that this has never happened, and in his 25 years on the land, Cosgrove has only had to bait his property twice. He warns that the current infestation is significantly worse than the notorious 2021 plague, which ravaged New South Wales (NSW) and southern Queensland so severely that an entire prison had to be evacuated due to structural damage.



How a bumper crop triggered an explosion
Another agronomist and farmer, Belinda Eastough, 59, spoke to the BBC about the last major outbreak as well.
"In 2021, they were in my handbag, the walls, the floors, and the pantry," says Eastough, who farms 5,500 hectares in Nolba, northeast of Geraldton—one of the hardest-hit regions. "This year, they aren't in the pantry. They’re staying out in the paddocks because that’s where the food is." She emphasized that the root of the issue stems from last year’s record-breaking harvest. Massive crop yields left behind an abundance of spilled grain on the ground. When unexpected summer rains hit, it triggered the growth of fresh green shoots, creating an absolute paradise for rodent breeding.


"Instead of just steak, they got steak and salad," Eastough jokes. "The mice were in absolute heaven."
Eastough, a veteran of nearly 40 years in agriculture, grows wheat destined for South-East Asian udon noodles as well as domestic bread and biscuits. In her canola fields, she estimates the rodent density is sitting at a staggering 8,000 to 10,000 mice per hectare."Usually, populations crash when the food runs out, but this year they just haven't. I'm living a nightmare."


A Race Against Time
Interestingly, the autumn months represent the critical window for sowing grain crops, making the timing of this plague devastating. As an agronomist, Eastough is urging local growers to deploy mouse bait immediately after seeding.
"If the baiting truck isn't right behind the seeder, the mice will come out at night and dig the seeds straight out of the furrows," she explains. "You could finish planting at 8 PM, come back the next morning, and find entire rows of your crop completely gone."
The added workload and expense are compounding an already stressful year. Global trade disruptions from the war have caused local fuel prices to double in just a matter of months. "The mouse plague is just another massive headache piled on top of everything else," Eastough says.


The math of rodent outbreak
According to Steve Henry, a research officer and rodent management expert at Australia’s national science agency, CSIRO, the sheer scale of the infestation is monumental. While an official "plague" is technically defined as 800 mice per hectare, parts of WA and South Australia are seeing numbers many times higher than that. During a recent field trip to WA, Henry counted up to 40 active burrows in a single 100-meter stretch, translating to roughly 3,000 to 4,000 burrows per hectare.


The speed at which the numbers multiply comes down to biology. Mice can reproduce at just six weeks old, delivering litters of six to ten pups every three weeks. "The real kicker is that they fall pregnant again within two or three days of giving birth," Henry explains. "They are gestating their second litter while still nursing their first."
Like Eastough, Henry emphasizes that the mental exhaustion for farming families is unique compared to other natural disasters. "With a drought, you can walk inside, close the door, turn on the AC, and get some respite. With mice, you go inside, open your cupboard, and they're in there. You go to bed, and they are running across your blankets."
