Steve,
We are now up to 28 stores. No, our research centers have just worked on keeping them out of cars. You can't do it all. I suggest using a live trap and then drowning the rats.After they have chewed all of your plants and garden cushions they are not cute any longer. It is hard to say what type of animal you have in your yard. We are researching only on pack rats and their behaviors. They also carry the germs and viruses.
I started trapping them were we live and was shocked how many I have caught.It is terrible to relocate and animal as it is a strange habitat and don't know food and water sources and other animals in most cases are the alpha. Termination is the kind thing than a slow death.
