In one sentence, describe what the following article is about: Diaphragm calls, or mouth calls, are tricky to use, but their range makes them popular with turkey hunters anyway. Unlike box and slate calls, they aren't held in your hands. Instead, a mouth call is a rubber or latex organ that fits in the mouth, up against the palate. Single-reed calls have the best range: you can make a wide variety of noises, and make those noises carry farther, with them. However, they're hard to learn. Double-reed calls are a bit more limited, but they're much easier to use. Since mouth calls don't require the use of your hands, they're convenient, but require learning a different set of motions. Find a quiet place where you won't be interrupted, and get your mouth used to the way it feels to have the call inside it. Here are some exercises you should try. Start by placing the call in your mouth. Keep the open end facing outside, then push the call up to the roof of your mouth with your tongue. Exhale so that the air is forced between your tongue and the call. Press your tongue hard against the reed, then blow. You will produce a higher sound this way. Now press more gently. With low pressure, the sounds will be lower tones. Exhale syllables, such as "chuck" or "pip," between tongue and reed. This will help you hear the distinct sounds they produce. Now that you've gotten the idea of how it feels to manipulate the call, you'll want to ensure a custom fit. If it feels a little too large in your mouth, carefully trim along the edge with clean scissors, then pop it back in to check the fit. Remember to trim conservatively--you can always cut more if you need to. The classic yelp isn't hard to do with a mouth call. Try saying the word "chuck" repeatedly. Experiment with different volumes and pitches to mix it up, and remember: a yelp is the first call you'll learn on the mouth call, but not the only one. Toms are usually the ones who cackle (or gobble), while hens are the chief cutters. There may be a sex difference in the way these sounds are deployed, but the motion for each is the same. Simply place your call in your mouth, and say "kit kit kit" several times. Make the sound quicker for cackling. Try listening to recorded cackles and gobbles until you feel you can get it right. Slow the sound down a bit to cut. Purring is especially tricky on the mouth call. Some mouth call users prefer fluttering their lips around the call (as if they're blowing a raspberry), while others roll a syllable in the back of their throat (as if they're gargling). Experiment to figure out which works best for you.
Summary: Buy a single or double-reed diaphragm call. Practice moving your mouth. Trim the call to fit your mouth. Begin yelping. Cackle and cutt. Practice purrs.

Remove the hair catcher or filter from an affected shower drain and clean it out thoroughly, removing all the hair tangled inside it. The key in destroying the drain fly's breeding ground is removing all hair, grime, and debris that the flies might lay their eggs in. Pour 1 to 2 gallons (4 to 8 liters) of warm water into the drain to moisten it slightly. Note that this is only needed if the drain is not used on a regular basis. Drains used on a daily basis are moist enough without taking additional measurements. Work a metal pipe brush into the drain, extending it as far down into the drain as possible. Twist the brush while slowly moving it up and down to remove grime from the sides of the pipe. Insert a plumbing snake into the drain and twist it through the pipes to pull out clumps of grime that lie further down. Apply roughly 4 oz (125 ml) of the cleaner around the edge of the drain. Applying the cleaner to the edge of the drain allows it to coat the sides of the drain and pipe as it glides down. Gel cleaners are formulated to remove organic matter. You could also use enzyme or bacterial drain cleaners to remove organic material. Vinegar, boiling water, and bleach are traditional remedies for getting rid of drain flies, but many experts insist that these methods are not effective. Baking soda and vinegar poured down the drain may kill the flies; it will clean the drain at least. You may need to repeat the same dosage of drain cleaner once a day for five to seven days total. After the drain cleaner has sat in the sink for several hours, flush it through with plenty of water. Use a plunger to remove any remaining organic matter trapped in the sink.
