  • Banish Biting Bugs

    SELF-CARE CORNER

    Insects like mosquitoes and ticks may annoy you during a summer barbeque or camping trip. But an effective bug repellent does more than avoid an itchy inconvenience. It may help prevent you from getting sick. Mosquitoes and ticks may carry diseases that are dangerous to humans. Many ticks carry Lyme disease and mosquitoes may spread the West Nile and Zika viruses.

    To help keep mosquitoes away, use a repellent that’s been proven safe and effective by the CDC. Look at the label and choose a repellent with one of these active ingredients:

    *  DEET

    *  Picaridin

    *  IR3535

    *  Oil of lemon eucalyptus

    *  Para-menthane-diol

    The CDC recommends tick repellents that have one of the following active ingredients:

    *  DEET (20 to 30 percent): use on skin and clothing, but not under clothing.

    *  Permethrin: use on clothing and gear only.

    In addition to a repellent, there are other ways to avoid bugs:

    *  Avoid wooded and brushy areas when possible.

    *  Walk in the center of trails.

    *  Wear clothing that covers arms and legs.

    *  Minimize time outside at dawn and dusk, when mosquitoes are most active.

    *  Throw out standing water in tires, buckets, birdbaths or other outdoor items at least once a week.

    *  Do a full-body check for ticks after spending time outside.

    What to do if you spot a tick

    If you find a tick on your skin, it should be removed as soon as possible. Here’s what to do:

    *  Don’t panic.

    *  Use fine-tipped tweezers to grasp the tick as close to the skin’s surface as possible.

    *  Pull upward on the tick slowly and evenly. Don’t twist the tick or try to yank it out quickly.

    *  If parts of the mouth remain after you’ve tried to remove it, use the tweezers to try and get them out. If you can’t get them out, leave it alone so the skin can heal.

    *  After you’ve removed the tick, clean the bite area and your hands with soap and water, rubbing alcohol or an iodine scrub.

    *  If the tick is alive, don’t try to crush it. Instead, put it in alcohol or an airtight bag or container. You can also wrap it tightly in tape or flush it down the toilet.

    *  Ticks can also be removed by your doctor if you can’t get it out yourself.

    *  If you’ve been bitten by a tick, contact your doctor for follow-up care.

  • Quit Bugging Me

    WELL-BEING

    As you enjoy the great outdoors, you may not see a bear, but you might encounter biting and stinging critters such as ticks, mosquitoes, and other insects.

    Bring along your own make-at-home first aid kit that includes assorted bandages and basic medicines such as a 1 percent hydrocortisone anti-itch cream, suggests Dr. Janyce Sanford, an ER doctor at the University of Alabama at Birmingham.

    Use insect repellant with DEET. Include tweezers to remove ticks (the best way is to pull straight up in an easy motion). And if anyone is sensitive to bee or wasp stings, carry an epinephrine auto-injector (EpiPen) when camping or hiking.

    Find out who in your party knows CPR before you might need it. Carry emergency supplies of food and light, and make sure you practice common sense.

  • Why Do Mosquitoes Always Bite Me?

    MEDICAL NEWS

    It has to do with how you smell, but scientists still don’t know why some breeds are attracted to different smells, said Jason Pitts, professor of biological sciences at Vanderbilt University.

    The source of the aromatic compounds that produce body odor are bacterial colonies that exist on human skin, particularly in dark, moist areas such as the armpits and between the toes. Pitts and his colleagues have discovered that mosquito antennae are filled with hundreds of tiny odor receptors, which are individually tuned to detect specific odors.

    Just as mosquitoes may love you, they may not love natural repellants such as clove oil, citronella, lemon grass, eucalyptus, castor oil, peppermint, lavender, and cedar oil. But almost all of these are less effective than the synthetic repellant DEET, and they need to be reapplied more frequently.

    Bet you didn’t know these pesky insects have a long-range system that allows them to track down potential prey from more than 100 yards away. The mosquitoes do so, in part, by sensing the carbon dioxide in human breath. When we exhale, our breath contains more carbon dioxide than the surrounding air, and mosquitoes can detect this difference-especially if you’ve had a beer or other alcoholic drink.

    To avoid mosquito bites, CDC gives the following advice:

    *  Use an insect repellant when you go outdoors. The FDA approves ones with DEET, picaridin. IR3535, and oil of lemon eucalyptus. Follow the product label’s directions.

    *  As much as possible, wear long sleeves, long pants, and socks. For extra protection, spray clothes, not your skin, with repellant that contains permethrin.

    *  Avoid outdoor activities from dusk to dawn or take extra care to use insect repellant and protective clothing during these times.

    *  Keep mosquitoes outside the house. Use screens on windows and doors or use air conditioning.

    *  On a regular basis, empty water that collects in outdoor buckets, flowerpots, pool covers and bird baths. Mosquitoes like stationary water.
