It drives me nuts when crickets get in the house, and it seems they only want to "sing" at night, when you're trying to sleep. I truly believe that they are ventriloquists also, since they are never where they sound to be. I've never been able to hunt one down, based on his vocalizations!
My son's cats are good at keeping the cricket population down in the house. They eat them - all except for the legs, which I find on the kitchen floor!
