We had the pest guy out this morning. He said that traps work only for mice, and not rats, and that the county is mandating that all rats and groundhogs be killed anyway since there is such an explosion this year. I asked him if ripping out our patio would do any good, and he said that it wouldn't, because they will dig under anything new we put up. We don't really have the money to have our concrete porches ripped out and relaid anyway... And there is nothing we can do about the A/C unit. Anything we put up to "block" the entrance they would dig under anyway.
If we lived in a rural setting I wouldn't have any problem with this. We lived in the northern Rockies for many years and living with mice, birds, deer, elk, and antelope were just a part of our life. But here in the city I cannot abide rats in my tiny back-yard. They are big enough to carry rabies, and they are destroying my small yard/play area for my daughter. I'm going to convienently forget about the groundhog living under my front porch

He's not bothering anybody.
The pest guy said a house-cat wouldn't do any good, but I know from experience that even well fed domesticated cats will keep mice away, I assume it's the same for rats. I guess we'll get a cat, even though I feel my daughter is too young for one right now, but I feel like he/she will keep the rats outside. My delimma is what to do about the outside rats, I don't want to let a cat outside.
This is just another reason I hate city living, there is no co-existing peacefully with wildlife. My neighbor has told us that she will call the health department if we don't set out bait, I was hoping there was a better way to get rid of them, but they are pretty well evolved little creatures.
I really don't want to hire an exterminator, the cost is high, the poison is dangerous (even though he says it's not), and I am opposed to killing things. I also really don't want rats or the health department sticking their nose into my home. WWYD?
