How tall is your crawl space?
You have a trap smart raccoon. Set a mouse trap in the cage trap, when it goes off it will startle the raccoon making it move enough to set the cage trap off. Leave the raccoon in the trap for at least 24 hours next to where it is entering your crawlspace as it's probably a female with young already. They will crawl away from where they are back to mom and you can collect them all, otherwise you will have several dead young raccoons stinking up the house later.
I got one last night out at my house. He was hanging out by the barn and getting ready to go under. But, I may have started a war. I think his buddies came back and ripped out my bird feeder last night. I feel like this is going to be a long and bloody battle.
It's been 3 days with coyote **** and electronic noise making thingy without a peep coming from below. I think he's gone. Wish you success HS in your war.
