hehe, vinegaroons are pretty freaky looking for sure. but totally harmless. their tils shoot acetic acid, like vinegar but more concentrated. stings in places like eyes/cuts etc but otherwise totally safe. No need ot kill them , they are harmless to us and are ok at killing cockroaches 
although i too just realized taiwan actually has real scorpions as well. other here said so, but i didnt believe them until this month when i foudn them myself.
see this thread for some pics
