Your letter to the bugman:  So I found this critter in a shed in Wisconsin.  It’s about an inch long (maybe more).  It doesn’t look like anything I’ve seen, and it was able to hop, almost like a cricket.

Silverfish

Dear Quinnell,
You have Silverfish, a common household pest.  According to BugGuide:  “often found indoors in warm, damp environments; the Common Silverfish (
Lepisma saccharina) is frequently seen in bathrooms and kitchens, whereas the Firebrat (Thermobia domestica) is usually found in basements around furnaces and in insulation around hot water and heating pipes; these and other species also occur outdoors under bark, in leaf litter, caves, ant nests, deserts, etc” and preferred foods include “omnivorous: starchy foods, cereals, moist wheat flour, glue on book bindings and wallpaper, starch in clothing made of cotton or rayon fabric; outdoor individuals eat lichens.”

Your letter to the bugman:  Hello Bugman,
Can you help identify this for me. This bug was crawling across my wooden desk. The body was about 1 cm in length, not including the antenna or tail. This is the second one I’ve seen in the past couple of days.

This is a Silverfish, a common household pest that will eat just about anything organic it finds in the home, including the wallpaper glue and the glue in book bindings.  We will postdate your submission to go live at the end of the month while our staff is out of the office for the holidays.

Update December 30, 2017:  Thanks to a comment, we now realize this is a Firebrat.

Common Silverfish

Dear Jordan,
This is a Silverfish, a common household pest that is generally found in dark, damp locations.  Normally we do not attempt species identifications on Silverfish, but we believe, based on this BugGuide image, that your Silverfish is
Lepisma saccharina, the Common Silverfish.  According to BugGuide, the habitat is “indoors in warm, damp environments such as bathrooms and kitchens, or in damp basements; rarely encountered outdoors” and they eat “crumbs and food scraps, dried meat, cereals, moist wheat flour, glue on book bindings and wallpaper, starch in clothing made of cotton or rayon fabric.”

Hi. Can you please identify this for me?  I keep finding these bugs in my bathrooms mainly.  Occasionally on the ceiling and they keep scurrying back to the wall.
