Not possible to eradicate, they produce at the rate…
A female rat can reproduce very quickly:
* Pregnancy (gestation): ~21–23 days
* Babies per litter: usually 6–12 pups (can be up to ~20 in some cases)
* Litters per year: about 6–10 times (if conditions are good)
So in total:
* One female rat can produce ~40 to 100+ babies in a year
And it gets more extreme:
* Baby rats can start reproducing in as little as 5–8 weeks
* This leads to exponential population growth
That’s why rat populations can explode so fast in cities.
