A severe mouse plague is overwhelming towns north-east of Perth, with residents describing roads covered in mice and infestations in homes and businesses.

Locals and farmers say current baits are ineffective and are calling for urgent approval to use stronger rodent poisons — a bureaucratic process that is dragging on.

The local MP says in the meantime, people are leaving town.

For the females, it's definitely fighting a flood with a bucket, but it's better than doing nothing.

If you grab a bucket of males and a little hand tool that expands and retract to quickly rubber band their balls you could probably knock out up to 90 an hour on average if you spend 40s prepping a new band and strapping it on each mouse, but it's less effective because only 1 male is enough to copulate with many females, but at least it robs food from viable males and females. This might be really optimistic though, theres a chance the mice could gnaw the band off. EDIT: a hot iron clamp would probably work better...

If you know of a more effective approach feel free to present it, but clearly the poison tactic isn't going to work when they've already established themselves and reached this number.

There are at least 10 million mice in a farming town of a few thousand. More mice are being born a day than you could accomplish that way. You're completely delusional if you think that is a viable plan.

The mice you castrate and spay will live longer than a day. They will consume resources for their entire lives and produce no offspring during that time. That's why this works. The mice compete with each other for food and to a lesser extent shelter.

One person doing 90 an hour for 8 hours a day would castrate in 260 days (work days in a year) 187,200 mice. 53 people could do 10 Million Mice.

Mice reach sexual maturity at 5 weeks old and can have a litter of 10 mice once a month. You literally cannot TNR your way out of this. You either kill them with poison or they consume everything that is edible in the area and then starve to death. Those are the only options, and I reiterate that you are completely delusional.

If every mouse immediately fucked, gave birth, and died then that would be worrying, but the point I made 3 times already is that the mice consume finite resources which reduce dramatically via spay and neuter.
