I've studied Wygodzinsky's 1972 paper on North American silverfish* and can confidently suggest that this one is in the genus Ctenolepisma, but I don't think its tails are long enough to be "C. longicaudata". At 10mm body length, this is probably not a full adult. Photographed in my garage, where they are numerous.
