I've been living in the same area for 13 years and the rodent battle seems never-ending. I refuse to resort to using poisons. I recently found a bait called rat X that is corn based. Supposedly rodents have a hard time digesting it and it doesn't hurt other wildlife, but I have no evidence that it's actually effective on rats and mice.
Currently, I'm using electric rat traps, but they're only good for one kill at a time. They're expensive. And tend to stop working after about six months.
I've tried the bucket technique, but the chipmunks and squirrels eat everything off those traps.
I've tried snap traps in many different configurations, but the rats are just too smart.
I've removed everything I can that would be considered a food and water source. My cats can only do so much with the mice, but they don't wanna mess with the rats..
I would love to hear people's input in solutions. I'm in New Mexico and this is an ongoing problem almost everywhere.. but all the locals use poison, which risk hurting other wildlife which I'm not willing to do
Thanks for your help in this
