Bert, as many snakes as you guys have, I didn't figure mice would be a problem.
I am assuming you are making a joke , in which case I had a chuckle
Snakes eat at best 1 mouse a day for week then find some where warm to lie & digest them for 3 or 4 days but most will take a single mouse then go off for 2 days to digest it because while they are digesting they are vunerable to preditors .
A single mouse can have a litter of 15 pups every 21 days and those mice will start breeding in 14 days .
Because of the bushfires the previous year, last season there was a mouse plague in the wheat belt and this year numbers are already building up.
My state lost 30% of it's wheat crop last year to mice .
Birds would take more mice in a season than snakes.
A breeding pair of eagles with the std 3 chicks in a nest will happily go through 30 mice a day .
And this is the big problem for farmers because baiting mice ends up killing the birds so a second plague happens almost the instant the first one ends .
Then once you have killed 200,000,000 mice what do you do with them ?
There was some news footage to make the city livers aware of the magnitude of the problem showing a line of B double tip trucks qued at a fertalizer plant all full of mice from a single wheat silo.
This year there is plenty of water so the farmers will most likely burn the mice alive by laying napalm around 30' wide around an entire field then setting fire to it
