Come on, SE,...If it has beady little eyes and a tail, the waste the disease spreading little 'baby rat' making machines...buy a bunch of old fashon rat traps and let them have at it...you can even put one of those little bells and put on it so you can even 'call' the time of death....
Nothing good about a rat, unless they are used for snake food...but I am not fond of snakes either!
Oh! Yeah! Be sure to put some newspaper under the rat trap, because if the little bugger gets poped just right, the blood and brains sorta splat about a bit... and you can just wrap up the whole mess and toss it.
