Here's what you can do to get rid of some common critters. * Bedbugs. These guys can hide under your mattress and behind your headboard. Their calling card is a cluster or line of itchy, raised bites that seem to sprout overnight. Although you may not see the actual bugs - since they're nocturnal - you'll know they've been there when you see the tiny red dots they leave behind on your sheets. So how can you fend off bedbugs? Wash your clothes and bedding in hot water and tumble dry everything on high heat. Also, call a licensed exterminator to determine if your home needs to be fumigated. * Ticks. Deer ticks - which can carry the bacteria that causes Lyme disease - are about the size of a sesame seed, but expand to the size of a sunflower seed after drinking your blood. Dog ticks - which can carry the bacteria that causes Rocky Mountain spotted fever - are about the size of a match tip, but can grow to the size of a grape. You can go to "tickencounter.org" if you're not sure what bit you. How can you remove the tick? Use a pair of pointy tweezers to grasp it where the mouth parts are embedded in the skin and pull it out with slow, steady pressure. Save the bug in a jar filled with rubbing alcohol. If an infection appears - like a red bull's eye around the bite - or you develop flu-like symptoms, the doctor will want to know what bit you. * Fleas. Their calling card is small, red bumps on your ankles or legs, and chances are, they've jumped ship from Fido or Fluffy. What should you do? Use a flea comb to inspect your pet. If you find fleas or their droppings - they look like dirt particles - vacuum all carpets and upholstery, and wash your pet's bed and toys in hot water. Talk to your vet about the best way to treat Fido or Fluffy's fleas.
