Bed bugs have been around for hundreds of years, and most kids and adults are familiar with this annoying small sized pest. These pests are drawn by carbon dioxide and warm temperature, and feed on exposed skin as you sleep. Day or night, these can feed at any time. According to their hosts, Bed bugs can adjust their feeding times. Here are some top things that you should know about bed bug bites-
It is a fact that most people are unable to feel the bite of these bugs. However, 50% to 70% of people who suffer from an allergy due to the bites are found to suffer from blisters and severe rashes. Generally, the reaction leads to raised, flat or small bumps, and itchy or red swollen skin. The areas that are bitten can get infected if scratched. Bed bugs have not yet been found to be vectors of diseases.
Various skin reactions are possible
Active substances like proteases, kinins or hyaluronidase are there in the saliva of the bed bug. These might lead to varied skin reactions, such as hemorrhagic nodule, vesicle, wheal or erythema. You have to keep in mind that the reaction to bed bug bites tends to vary from one person to another. Some individuals show no response to the bites of bed bugs. It is true that the person sleeping next to you can be affected differently by bed bug bites, even when you share the same bed.
Secondary bacterial infections
Secondary bacterial infections may arise from the site of the bite. These can result in lymphangitis, cellulitis and/or eczema. From a bed bug bite, occasional systemic reaction may arise. In a few cases, in case of intense bite reactions, there can be repetitive scratching. It can lead to skin lesion, which might get more complicated due to impetigo.
In a few days, most welts tend to heal. However, in some abnormal cases, there can be a persistence of the wound for a few weeks to a few months. Generally, an anti-itching ointment can be useful. However, in case of infected bites, a doctor can be useful.
