Wow, you are up early, 6:00 is my normal waking time. 3:30 is a bit too early for me.
I know poison will work if I shove it down the holes but having my dogs eat it is another fear. I would go crazy if they were harmed in any way. We had poison in the large black traps and the hens must have tossed the box around and got some poison out, I found little bits scattered all around their run one day.
Before we put poison out last year, we used to have chipmunks and now the chipmunks are gone. I have to wonder if they ate it. Probably. I used to love seeing the chipmunks.
We got filmed to be part of an animal series on rats, but our segment never aired. They weren't able to film the rats at all and guess we weren't exciting enough for them. Now it seems we are overrun. These were the guys who came to our house. The film crew was here for about 2 months on and off. http://animal.discovery.com/tv/rat-busters-nyc/about-the-show.html
Donna, nothing to do with rats, but I found stepping stones for my garden on craigslist. Going to pick them up tonight. Craigslist rocks!!
