Bedbugs are small wingless parasites that live in bedding and soft furnishings. They feed on the blood of their victim and are pale coloured when hungry and reddish brown after a feed from their host.
The sting of a bee or wasp is a defence mechanism - it is to protect them from us. The sting is poisonous and painful, and can cause severe reactions. Most people get a painful sensation at the time of a sting, and the area swells and reddens.
Insects that bite do it to get access to your blood as that is what they feed on. Biting insects include mosquitos, fleas, sand flies or midges and bedbugs.
