Subject: What is this bug?! Are they harmless?!?! Please help!

Hi there! I’m from Windsor, ON Canada and for a while now I have been seeing these small bugs coming in and out from underneith the moldings of my bathroom wall. I never see them during the day but I work midnights so when I get home and I open the light to the bathroom there it is! It sees the light and scurries back into the cracks. The house is only 3 years old and I’m thinking they’re just visiting from outside because the only place I see them coming from is the one bathroom wall that faces the outside. Haven’t come across them elsewhere in the house. What are these bugs? They’re very small and you can’t even tell they have legs unless you look very close so they just look like a very fast baby worm wiggling away. You can get a better look at the colours and shape of it from the photo I will provide. Thanks!

Dear Sonia,
This is a primitive insect known as a Silverfish, and they are common household pests.  According to BugGuide:  “often found indoors in damp environments; the Common Silverfish is frequently seen in bathrooms and kitchens, whereas the Firebrat 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.”  They have plenty to eat indoors.  According to BugGuide, they are:  “omnivorous: starchy foods, cereals, moist wheat flour, glue on book bindings and wallpaper, starch in clothing made of cotton or rayon fabric.”

I’ve been finding these bugs in my bathroom and anywhere that moisture is. Like the kitchen sink or in drying dishes. They are very quick bugs and move so fast!
Do you know what they are?

Hi there,
I’m wondering if you can help me identify this bug? I started noticing them about a year ago, approx once every few weeks, mainly in the bathroom in the middle of the night or early morning. They scurry away when the lights go on. The one in the picture attached is approx the length of a penny, but I’ve started to notice babies!!!! Noooooo! We live approx 30 mins east of Vancouver, BC in a ground floor apartment building. The building itself is approx 20 years old, made with concrete and wood (so I wondered if it is a wood-dwelling bug). They tend to scurry under the baseboards. I’ve seen a few in the kitchen now and I need to stop this scourge! Thanks in advance!

Dear Shannon,
The Silverfish is a common household pest that can be extremely difficult to eradicate.  Silverfish will feed on a wide variety of organic substances in the home, including some unconventional items like the glue binding of books and wallpaper.  Your observations that they are found in the bathroom and at night are very accurate.  They prefer damp surroundings, especially near sinks.

I live in San Francisco in the near the corner of Tennessee and 18th street and found this bug. Can you please help me identify it? There does not seem to be an active infestation, but I wanted to know for future reference.

Hi Alex,
This looks like a Silverfish in the order Zygentoma to us.

Thank you for the Email.  That looks correct and is a big relief.

They are considered household pests.

Yes, I understand.  We have seen a few silverfish around, but compared to when I thought it was a bed bug it seems better to me.

Yes, much better than Bed Bugs.

Hi Daniel
If we ever needed proof that all life on earth originated from the sea then this insect surely must be it. I found it in a wooded area far away from any water source. It looks more like a prawn than an insect. Would you have any idea what it is ? It was about an inch in length and moved quite fast. It was sitting on a leaf as you can see from the photo.

Hi David,
This is a primitive insect in the order Microcoryphia, and the members are commonly called Bristletails.  Compare your individual to this Rock Bristletail pictured on BugGuide.  According to BugGuide, Bristletails are:  “wingless; body cylindrical, brownish or yellowish with darker mottling or irregular pattern; thorax arched dorsally; tip of abdomen with 1 long medial filament and 2 shorter lateral cerci; long thread-like antennae with many segments; eyes large and meet in middle; mandibles articulate at one point only; short lateral styli (rudimentary appendages) on abdominal segments 2-9; able to jump up to 10 cm by snapping abdomen against ground” and they inhabit “outdoor grassy or wooded environments: under bark, in leaf litter, rock crevices, or under stones; not normally found in homes, does not breed indoors, and not considered a pest.”
