How to get rid of a rat in new-to-me truck

[Grumpy old man]

That's his truck now and I'll bet there's a lot more than one ! it's been infested for so long already I don't think I would have even brought that home . They've probably been chewing on every wire and there's no doubt the dash is full of rat treasures , Give it a few days and you'll know if the rat poison worked on some of them it will really start smelling bad , The poison works by making them hemorrhage internally and they will seek out water . I'd tow that away from your house asap ! Buy a BIG snake !
