Bed bugs were a problem that humans thought they had got under control, but recent years have seen a 500% increase in their occurrence. Previously confined to hotels and transport hubs, they are increasingly becoming common in peoples homes, and as they are easily passed from person to person, they can be easily spread. Bed bugs generally emerge at night and draw blood from humans by piercing them with twin tubes. One side anaesthetises the wound and the other side draws blood. The result is a raised, itchy lump on the body, which can take up to a week to appear after the initial bite. Though they will heal of their own accord, anti-histamines are often administered to control the intense itching, whilst hot water can also help alleviate the symptoms. Ultimately, the cause of the infestation must be treated in order to prevent reoccurrence.
