Heck I forgot about this for a second, but I killed a rat with raid wasp spray a few years ago, that stuff is bad medicine.
Hear Ya!
I did the same thing with a can of Brake Cleaner. I opened one of my portable buildings that I keep garden tools in...and saw a large field mouse (almost as big as a rat) run up along the top plate of the wall and stop in the corner.
There was a can of brake fluid there on the floor so I soaked him down real good and that mouse dropped to the floor, wiggled for about 15 seconds and expired.
Didn't expect that! I was hoping he would just run out of the building, but it killed him in less than 30 seconds.
