I understand mice have built up a good immunity to the general over the
counter anticoagulant baits, requiring multiple ingestions to croak. May
want to see if there's an exterminator's supply place that will sell you
something stronger, assuming as has been said this is not a threat to any
kids or pets.


Most of the newer generation of anticoagulants are made to be for
multiple feeding before death. Not so much for mice, but rats are known
to of eaten baits, but not enough for a lethal dose to occur and the
sick rat can learn what food made it sick. If it takes several days for
the effect, it is unable to associate what made it sick, along with more
of a probability that it has taken in a lethal dose of the product.
Buying from a pest supply house is not going to give you stronger toxin,
but the baits they sale are going to be made more for the rodents taste.
The rodents have to eat it if a bait is going to kill it.
