We did put out trap last week, caught 1 the size of a 250ml cup. Non since, but this morning the rat poops are just everywhere.
Lime will make whatever small feed on the ground decompose faster.
I have 2 dogs and my neighbours have dogs that all in the garden all day, so baiting rat I can not do. My dogs are inside at night so they can not do much. My miniature fox terrier dog only have a few teeth left so he is not much risk the those rodents.
Edit to add that those nasty rodents dug up and ate all my sweet potatoes.
