I do, too, but there's a lot of cali to cover. are you in teh mountains? by the coast? in the foothills? on the valley floor? up way north? what kind of creepy crawlies are common around your area. like i said, they eat bugs alot of times... might be more "humane" just to let the bugger go on his way, though. also, remember, he's not warm-blooded... needs to stay at a quasi warm temperature... too hot or too cold'll kill him.
does he look like one of these guys?
