I use to trap rats (4 legs) in a jaw type spring trap. Peanut butter with hominy grits mixed in is the most effective bait.
Like blowing up balloons....Coke would be good in a bowl as well....if they would drink it.I have a tray of homemade rodent killer in my barn. Either they are in hiding or dead.
Mix together:
1 cup sugar
1 cup flour
1 cup baking soda
Put in a tray with water nearby. They will be thirsty.
I meant coca-cola
I have no issues in my garage,but a friend has a commercial shop with many rats in the hood.I bought him 3 plug in jobs and they helped along with the always loaded pellet pistol.The best is the little execution chamber that gets plugged in! A little peanut butter on the metal back wall and 1 is found every morning!
