Summer means more time outdoors–and more opportunity for annoying critters to bite you. Most of the time, all you’ll get is a little red bump with itching and maybe a little swelling. These insect bite symptoms can be treated easily with anti-itch creams and over-the-counter antihistamines. Occasionally, bites can cause allergic reactions that lead to severe swelling and shortness of breath; if that happens to you this season, you need to be seen by a doctor.
Bed bugs are obligatory bloodsucking. They have mouth parts that saw through the skin, and inject saliva with anticoagulants and painkillers. Sensitivity of humans varies from extreme allergic reaction to no reaction at all (about 20%). The bite usually produces a swelling with no red spot, but when many bugs feed on a small area, reddish spots may appear after the swelling subsides. Bedbugs prefer exposed skin, preferably the face, neck, and arms of a sleeping person.
Bed bug bites can look a lot like other insect bites. Some clues that can suggest the presence of bed bugs include finding red, itchy bites upon awakening - especially if the bites line up in a row on the skin. Bed bugs typically bite at night on exposed areas of skin, so the bites are most commonly found on the face, neck, hands and arms. Although some people develop a bite reaction immediately, others may take two to three days before a reaction becomes noticeable, and not all people have obvious bed bug bite symptoms. A bed bug bite can appear as a tiny puncture wound without a surrounding reaction, and can easily be missed. In fact, 30 percent of individuals living in bed bug-infested dwellings report a lack of bites or skin reactions. This appears to be more common amongst the elderly. On the other hand, other people have exuberant reactions, with large, red, raised and itchy welts. This is especially true if one becomes sensitized to bed bug bites, so that with repeated bites there is an increased risk of an exaggerated reaction to bed bug bites.
