I love your web site!
We recently moved into a new house in the Phoenix, AZ area and we are seeing a lot of small (1/4 to 1/2 inch) bugs in the house that look a little bit like the silverfish that I used to see back in Virginia. They are very fast runners and they like to sit high up on the walls – particularly in the corners. They are beige with 3-4 brown stripes running from side to side and they have long thin antennae and what looks like antennae off the rear of the bug as well. They are extremely soft-bodied and, when threatened, their first response is to try to crawl deeper into the corner rather than simply run.
My camera will not let me zoom in close enough to get a decent photo, so I hope my description is adequate.

After reading more about silverfish and firebrats, I suspect that these are the latter. Oddly enough, we don’t find them in the damp areas of the home as much as in the dry. We do not find them in sinks or drains or in greater quantities in the bathrooms or kitchen. Right now, I can find 2 or 3 of them in the living room and each bedroom, parked at the ceilings. The house stays pretty dry (<30% humidity most of the time) and there are no signs of moisture anywhere. They do not seem to be more active at night and they do not seem to hide during the day. The body is less carrot shaped than indicated in the drawings and photos I’ve seen on the web, with a slightly more rounded rear. My wife calls them “trilobites” because of their prehistoric appearance.

Hi Bob,
I am inclined to agree that you probably have Firebrats. They are very primitive insects and your wife likening them to trilobytes is interesting.
