Recently, I had an infestation of 'bugs' which managed to die the next day. Now, they are infesting the outside and fly up when you approach them. The top photo shows how tiny they are and what they look like. It didn't 'bite'. No idea if they are bugs, beetles or insects. Read about the differences here. The short story is that bugs suck, literally. I have cunningly managed to miss a close up of its eating equipment, sorry.
