agreed try all other options before tearing my apt up lol. also im not sure of your finacial situation but you could purchase a rigid see snake to locate the exact spot hes at and tear out that small area if its the last resort. i lost one under my tub and i purchased it to locate him and it was awesome. they will show u anything in any small craks or walls. its a wand with a camera in it that attaches to a hand held lcd screen. they go for around 220.00 to 300.00 bucks but u can usually find them on ebay a little cheaper.
