Some species of crickets get pretty big before they get the hard exo skeleton and start chirping. You can probably call some breeders and find out. I'm sure they will be forthcoming and it will help keep you sane.
Wild ones invade my basement in the spring and summer, and my fiancee has been know to throw shoes, boots and even video games in the general direction of their chirping. Now we run the dehumidifier all spring and summer. That drives me nuts (I don't mind the crickets) but I got sick of things getting thrown across the house, so I conceded. hehe.
