About 6 months ago I noticed a new friend in my apartment. It lived in my bathroom and only came out during the night (not sure how it knows when it is nighttime if there are no windows in the bathroom). I called him Jimmy. Seems harmless. About 8mm in length. Moves fast but is not running away scared. It has now moved to the kitchen. I think it has 6 legs, antennae and a weird double tail.
Here are pictures, low quality because it is tiny and my phone camera is not so good.
I live in Ireland.
