That reminds me of a friend in Vancouver, back in the early '90s, living on a 2-story houseboat in the harbor....she raised crickets in the living room, so that from her bedroom upstairs she could hear the crickets chirping at night, which soothed her at bedtime and helped her sleep. Based on the times I slept over, I came to agree that her arrangement made sense; I did feel soothed. Just like I did as a child, listening to the crickets outside chirping through the screened bedroom window, with the stars twinkling above. Maybe I'll look into raising a few crickets myself one day....better than warm milk, perhaps.....
