When it comes to household pests, John Hodgman recommends either bathroom knives (e.g. for axolotls) or fire (e.g. for Scotty dogs). I'd say go with whichever you have proficiency in.
Of course, if you have some Sweet-Sweets, you could always get the yukkuri on your side and use 'em to draw aggro from Than'Garr Almorak the Semi-Speakable. Always a worthwhile endeavor.
