Rat Infestation

I'm not sure how many rats you need to have to classify it as an infestation, in my books, one is enough. Coming from Alberta which claims to be rat free, this was my first run in with these critters.

We first noticed the rats when the plants around our house started to die (as you can see in the picture). Next we noticed holes begin to appear around our house and the final straw was when they began running to and fro in our ceiling. We went to go buy some traps but the local store didn't have the good traps that clamp shut when the food is disturbed. All they had was glue. We bought a couple of glue traps, set them near the holes only to discover the that food was taken but no rats were stuck in the glue. A little while later we were able to buy the good traps and we even got some rat poison. Poison was placed in the various holes and that night we heard the trap clamp shut and victory, we had our first victim, a tiny little baby rat. We weren't sure how many rats we had but were pretty sure that these minature rat wasn't the source of all of our problems and not long after we heard some loud scampering in the ceiling and more holes were appearing. The traps were reset and more poison was set out and not long after, snap, another victim, this time a huge rat, maybe the baby rat's momma (pictured). We still don't know how many more rats are left although there is a foul odor coming from the porch outside our house. I have a feeling that poison worked its magic and a rat or rats crawled up and died in the hole. Who knows how long the smell will last, at least they haven't crawled up in our ceiling to die there!
