Snake got bitten by mouse.

Hi.

My Cornsnake just got bitten by an adult mouse while feeding.
Now it has a little wound right on the neck behind the neck which is bleeding a little bit.
What should i do to keep it from getting infected?

THX

Clean it up and just put some Neosporin on it WITHOUT pain killer. The pain killer is potentially harmful.

neospsorin with OUT! pain relievers

Ok,i could not clean it completly cause he just swallowed the mouse and i didn't want to put him under too much stress,but i cleaned it a little bit and put neosporin without pain killers on it.
But normally he likes to dig himself in after feeding,isn't that harmfull?
I use coconut shavings as beeding.
