I have too many other animals to even think about poison!!! Way too dangerous! I've been setting a rat trap, and did have them all cleared out. A new one moved in recently. They have been problematic for the past 3 decades here, and plague all the houses in the area. Before I moved in to keep an eye on my mother, and cleared the last batch out, she had ignored them and they chewed a hole through her refrigerator! I have been patching holes as I renovate her house, but this one in the garage is elusive, and knows what a trap is. I'm going to have to try a havahart on him next, since he may not have any experience with one. He is also below my power junction box in the wall, and has likely done some line chewing (lost power to half the garage), so I'm going to have to rip the Sheetrock off in that area to get at the nest and assess the damage. There are 7 cats here. Why none of them bother with the rats is one of the great mysteries of this age... I have never had problems with rats anywhere else, but according to other folks on the road, they have pretty much colonized the area. It's been a constant battle - I clean out the population and more arrive from the places that are less dedicated to removing them....
Rats are neophobes - they are suspicious of anything new. If you put down traps leave them in the same place for a while so that it becomes part of the scenery. Patience! you'll get 'em!
