Good choice. Many a night you have probably lain awake while one of these insects chirps a "lullaby." You stumble around in the dark in hopes of finding the culprit, but alas never do. Before you know it, you're wishing for the death of all household crickets. So, what's so great about these little black symphonies anyway?

Well, generally speaking crickets are good for two things: eating and good luck. Many entomophagists enjoy eating crickets, and there are hundreds of recipes out there with crickets in the dish. Many cultures, including in the United States, believe these insects bring about good luck. Some cultures believe that stepping on a cricket will bring rain, others believe crickets bring money and hope.

Besides keeping you up at night, crickets can also nibble on your plants, but these insects only live between two and three months, so damage to your foliage will be minimal. Another interesting fact about crickets is that their song becomes louder and faster as the temperature rises. Think of their chirps as little cricket thermometers! And if you're the romantic type, keep in mind that the male cricket is really just serenading his lover — maybe then you'll be less inclined to wish the death of him. And hey, who would want to interrupt such a romantic moment, anyway?!
