Hi, I am a professional pest controller,
Mice are very difficult to eradicate completely, Cats may catch the odd mouse, but are practically useless in knocking back numbers of a rat or mouse infestation due to the speed that mice and rats can breed.
Mice are prolific breeders; as many as 13 litters can be produced in one year.
The number of young per litter averages about six. The gestation period is approximately 19 days, varying from 18 to 20. They develop rapidly; at the age of 3 weeks they are fully weaned and at the age of 4 weeks some of the young females are ready to breed, they have a short gestation period of 22 to 24 days, the litter of approximately 8 pups is born these babies are generally able to breed after 3-4 months and the cycle goes on......
My advice is to call a professional pest controller to deal with the problem; they have a lot more experience and equipment to deal with a problem safely and efficiently than can be written on a label of rodenticide that can be bought from your local hardware store....
