Millions of mice are terrorizing Australia’s farmers, and there is no relief in sight.

The mouse pandemic, which began ten months ago, has sabotaged the drought recovery with the mice infecting fresh crops and destroying thousands of dollars worth of machinery.

Mice are biting individuals in their beds, causing residents to be rushed to the hospital in critical condition.

Because of how rapidly they breed & their ability to hide, it’s impossible to determine their true numbers.

Effects on other animals

Chemical baits used to control rats, such as edible baits, can endanger human health. It has the potential to poison both native animals and mice. Chemical bait stays in an animal’s body after it dies.

Thus other animals who consume bait-killed mice may grow sick or die. As a result, it’s critical to avoid unnecessary interaction with the bait and keep it away from children and domesticated and wild animals.

Food, beverages, or feed must not come into touch with the bait. It may pose a threat to fantastic parrots, with the potential to wipe out the species.

The chemical bait can have far-reaching consequences throughout the food chain, jeopardizing mice-eating species such as raptors and snakes. The EPA looked at bird deaths in Forbes, Dubbo, Parkes, Condobolin, Narromine, and the Riverina, including pigeons, galahs, and magpies.

Chemical bait is mild to extremely hazardous to fish. Toxicity to certain other aquatic life ranges from moderate to high.

Effects on the Land

Chemical bait can seep into soils and groundwater, contaminating drinking water and drifting and polluting the atmosphere.

Soil biomass and microorganisms, including fungi, bacteria, and earthworms, can be harmed by chemical bait.

Microbial biomass is a solubilized element of organic matter in the soil that plays an important part in the cycle of soil nutrients.

Effects on humans

Symptoms include nose bleeds, bloody urine, bleeding gums, black tarry stools, and soreness in people who accidentally ate chemical bait.

Headaches, abnormally heavy periods, sore throats, shortness of breath, muscle aches, abnormally heavy periods, & bloody mucus are some of the less common symptoms.

Chemical bait might irritate the skin if it comes into touch with it. It can cause severe swelling, redness, and irritation if it goes into the eyes.

Chemical baits may be more sensitive in children than in adults.
