So theres a GDKC in my camp

Packing up to leave my camp which is a travel trailer and heard something crawling underneath it when I got out of the shower. Thought it was a rat so go outside and crawl underneath to see if I can find where it got it.

Trailer has an insulated subfloor which is jut a layer of insulation with a heavy tarp like material on the bottom. Was looking for hole and then saw the tell tale imprint of satans spawn slithering on the tarp. I beat around on the tarp with a pole trying to push it to a corner where I can cut a hole with a pole saw and get the fricker out then look to my left and see the biggest rat snake I've ever seen poking his head out a hole staring at.

I beat around some more but it didnt come out, I backed out and sat there for 10 min or so hoping it would come out but no sign of it. Ended up running to the store and bought a couple bug bombs, stuck four of them in the sub floor and set them off hoping either to drive it out or suffocate the devils creation. waited another 20 min and nothing came out beat around some more and couldn't get it to move. So rolled out hoping either its dead or it snuck out while I went to the store.

Heading back down Thursday should I prepare flame thrower? Really don't think I'll be able to sleep if that spawn on satan is slithering around under the floor regardless if it can't get into camp or not.

TL:DR Huge rat Snake in subfloor of travel trailer, not 100% sure its out or dead, should I start looking for new camp?
