Okay, here's the plan: Equip yourself with 4 100cc vials of holy water and two bottles of good cheap cabernet sauvignon (sp?), and some borax. Ask your neighbor to borrow his/her weedwhacker, an umbrella, a vinyl record turntable, three boxes full of nothing but mismatched lids to tupperware containers and a flamethrower (if your neighbor is one of the normies, you may substitue the flamethrower with a standard groundhog eliminating grenade or one of those cool bar-b-que lighters taped to a can of hairspray. )
Bless yourself with the holy water (just in case) and very quickly drink all the wine (just in case, in case). Grab the flamethrower/grenade/lighter and hairspray combo and start manually eradicating the bastards. Splash a little borax about for show. If this doesn't work, take all the rest of the crap you borrowed from your neighbor and have a garage sale. For some reason, garage sales are a great way of passing along evil entities, making your home more of a rest stop than a permanent residence. The End.
(Please note that if you're dumb enough to actually attempt to tape a can of hairspray to a bbq lighter and you blow yourself up, you totally didn't hear that idea from me, dig?)
