Location of insect bites
Bites and itching on the scalp are usually ue to head lice.
Bites, at night, on the face, neck, arms and feet, i.e. on those parts of the body which normally stick out from the bedclothes, may be due to bed bugs: but of course they may be gnat or mosquito bites.
Tiny itching ‘dots’, mainly on arms, legs and neck, are caused by red poultry motes.
Red spots, usually very irritating, particular in the armpits, on the inside of the thighs and between the fingers may be due to itch mite.
Bites in series or groups, on the stomach or back, under a trouser belt, or under any restriction, are usually flea bites.
Bites and itching around the genitals (or in the armpits) are normally due to crab lice. Characteristic blue spots may appear due to discoloration of the skin caused by the crab louse’s salivary secretions.
Bites, at night, on thighs or shoulders will often be flea bites. Fleas like to crawl in beneath the body, and bite where it is in contact with the bedclothes.
Bites on the legs will usually be made by fleas, which sit on the ground and jump directly on to the legs.
