Yucky! You remind me of my daughter..I would collect the slugs in a can and smash them outdoors for good measure..If you can't find help..a good silicone caulk will do the job..be sure and have a smoother to smooth the bead.. and do remove extra residue on surfaces where it isn't wanted.. quickly..Good Luck!
Watch your step
My wonderful DH’s commanding officer just emailed me, he’s coming over after work to do slug-related caulking and coroner duties, lol! Woo hoo! A colonel that makes house calls!
