I've noticed a bug crawling around my bathroom for the past few months. It seems there are more than one after finding one near the front entrance of my apartment. I live in a basement in Ontario Canada and I'm curious to know what these critters are. The pictures attached are of a couple that I've managed to catch. They are a half centimeter (0.2 inches) and they move quite quickly. They are silver looking but once you turn them over they are white on the bottom. They move like a centipede and they do not have a hard exterior. They are quite easy to squash. They tend to avoid light so that when I turn the bathroom light on they scurry off to underneath the baseboards. Once I notice them its usually too late to track them down but I often find them hiding for instance under the bathroom mat.
I've only noticed them during the winter but that could be coincidence.

Any ideas what type of insect these are?
