I'm thinking that in the future you won't have to ask the GF forsome time in the woods alone.

Fill the tub with very hot water, a gererous dose of bleach and take a good long soak. You'll survive.

I hope you and the GF are at the "very intimate" stage of your relationship because no matter what you do now you and she are probably going to need each others help . You may think you got them allbut a few days/weeks from now you more than likely will discoverone or morewhere it is impossible for you to see it or get ahold of itto remove it without assistance.
