@SW-User It run under my bed when I came back and turned on the light (first time I've noticed it) and then I was like "well, might as well clean this place so I can move the light (since it obviously repels them) and then kill it with a shoe or something but while I was cleaning I noticed it laying on its back on a place I was standing 5 secs ago. A slipper was the closest I had so I rammed it with a couple of not-so-brave screams. I hope never to encounter it again...at least not in the next couple of months.
I'm sorry I killed it but those damn bugs are just so fast - there's no way I could catch it (especially not with those small, hysteric movements) and throw it out peacefully.
