For the last 2 weeks I've been being bitten by something. It is very tiny (about 2mm long) and black. It bites many times in a single attack and the bites are instantly painful. I managed to see one today by dropping my trousers when I felt it start biting.
Unfortunately I'm reacting really badly to them and they swell up almost immediately. About 3 hours later, they calm down to a large red patch, about 4cm square, but are still really, really itchy.
I'm dosing myself up on anti-histamine and using anthisan cream on the bites themselves, but I obviously can't keep doing this indefinitely.
We don't have any pets, and we have tiles or wooden floor downstairs. I've washed all the bedding.
What is it, and how can I get rid of it! Any bright ideas?
