I have a severe RAT problem.....does anyone have a solution that works well?

Just One Bite brand works great. It used to be available in small packages, but now you have to buy a whole box--around $35 but is worth the price and will last for years. That is the brand name for bromodiolone that Flockwatcher recommended. I have dogs, cats, and 70 chickens and have not lost any to eating dead rats. In fact I rarely get them, and I live on a 110 year old farm. I just keep replacing bait in a locking bait container--it very seldom disappears now.

I agree
