Australia is once again facing a threat, with the situation unfolding in a way that bears more resemblance to the plot of a disaster film than a mere agricultural problem. Across a number of regions in Western and South Australia, there have been reports of a massive invasion of mice, which are destroying crops, contaminating grain stores and infiltrating homes, offices and industrial premises. Of particular concern are reports of damage to communication cables, computer equipment, network hardware and even hardware crypto wallets, on which owners store their digital assets.
For cryptocurrency owners, the problem extends far beyond ordinary financial losses, as most hardware crypto wallets operate via a USB or Micro-USB connection, which is used as the primary or backup method of connecting to a PC or smartphone. Furthermore, passwords and recovery phrases are often stored on paper. Therefore, if mice damage the cables, the device casing or the records, regaining access to digital assets can become extremely difficult. Sometimes – even impossible.
Similar risks arise for servers, routers, uninterruptible power supply systems and network equipment that underpins the country’s financial infrastructure.
It has now been recorded that in the worst-affected areas of Australia, pest populations reached up to 8,000 individuals per hectare, which is 10 times higher than the most critical threshold of 800 individuals per hectare.
The agricultural and economic consequences are already being assessed as extremely serious. Representatives of the agricultural sector are warning of potential crop losses amounting to up to 1 billion Australian dollars, which equates to 719.42 million USDT, 11,418 BTC or 425,170 ETH (as of early June 2026). For example: the previous large-scale mouse infestation in New South Wales in 2021 cost the economy over 600 million Australian dollars, whilst the historic ‘mouse plague’ of 1993 caused tens of millions of dollars’ worth of damage and destroyed thousands of hectares of crops.
Rodents pose a threat not only to property, foodstuffs and the contamination of animal feed. They are carriers of a whole range of dangerous diseases. Among the best known are leptospirosis, salmonellosis, tularemia and hantavirus infections.
A separate problem is damage to engineering infrastructure. Mice gnaw through the insulation of electrical cables, fibre-optic lines, hoses and control wires for machinery. As a result, tractors, combine harvesters, irrigation systems, air-conditioners, washing machines, computer equipment and telecommunications network components break down. Australian farmers have reported instances where rodents have literally paralysed farm operations by damaging the wiring in machinery and storage facilities.
The Australian government and industry regulators have already launched a comprehensive campaign to tackle the infestation. In 2026, the authorities even granted emergency authorisation for the use of stronger poisoned baits to control the population. Farmers are advised to make widespread use of zinc phosphide baits, monitor pest numbers, treat fields during sowing and step up surveillance of grain stores.
What can be done to minimise losses?
Cryptocurrency owners should store their seed phrases in fire- and water-resistant containers, keep several backups, and regularly check the physical condition of their equipment.
Ordinary citizens should remove any open access to food sources for rodents. Sealed food containers, regular disinfection of premises and protection of electrical wiring. This minimises the risks of property damage and the spread of infections.
The latest mouse infestation in Australia, yet again, highlights the vulnerability of the modern networked world, as a similar problem could threaten any other country tomorrow.
