Silverfish
(03/14/2008) Hello! Identification help!
Hi,
I have attached a picture of a bug I have found in my room.
Just curious if you know what it is and a little about it?
Thank you so much!
Matt

Hi Matt,
The Silverfish is a primitive insect that is generally cosidered
a household pest.

(11/19/2007) please help figure out what this is!
I find this bug in my master bathroom. It's always crawling
on the wall, only one by itself but i'll see it once or twice
a week. Sometimes it's on the wall of my bedroom. Any idea
what it is? Please!!!
Nancy

Hi Nancy,
We have received several requests in recent weeks to identify
a Silverfish, but we have not posted a new image of a Silverfish
since it was Bug of the Month in
March 2007. Silverfish are primitive insects that can become
established in homes and become household pests. They are
usually found in dark damp areas and they are known to damage
books by feeding on the organic glue and sizing in the binding
and also do damage to wallpaper. They eat many forms of dry
organic matter and will also feed on sugar, flour, breakfast
cereals, fabrics and insulating materials.

(03/02/2007) What is this?
Hi, there,
Recently I can see this kind of bug everyday in my house.
First I thought it is a House Centipede. But I found there
are not enough legs. Please tell me what it is and how to
control them (I killed 2-3 everyday). Thanks and regards
James

Hi James,
This is a Silverfish, a primitive insect. They are considered
household pests. They are found in dark, damp areas, often
the bathroom and basement. They will eat many things, but
are fond of glue that adheres wallpaper to the wall and the
glue in book bindings. Your timing was perfect and your photo
quite gorgeous, so we are making the Silverfish the featured
Bug of the Month for March 2007.

(01/06/2007) Help identifying a bug
Hi,
I attached a pic of the bug that has been plaguing my room.
I found 8 huge ones around and under my bed (about 2"
long), and have found several smaller (0.5") to bigger
(1 - 2") ones randomly in other parts of my room and
in boxes. Could you please help me to identify it, and if
so would you know any way to keep them from coming back? Thanks!
Kym

Hi Kym,
This is probably the most beautiful image of a Silverfish
we have ever seen. If we could tell you how to eradicate the
Silverfish from your home, we would be fabulously wealthy.
They are found in dark warm places, and can squeeze through
tiny places. They are found inside walls as well. They are
generally considered household pests as they will eat starchy
substances, including book bindings, fabric and wallpaper
glue. They will also eat many food products including sugar,
flour and cereals.

(08/06/2006) silverfish photo
After thoroughly searching your website, it seems I have silverfish
in my apartment (although this is the first one I have seen).
Just thought you might need another photo to post, as most
of the pictures of silverfish seem to be from the top angle.
I live in Richland, Wa (south-eastern part of the state),
and this silverfish was moving slowly across the carpet, and
would repeatedly jump away if I got too close to it. It did
not seem to be a fast runner, as my shoe was still able to
get the better of it. Thanks for your site, it has been very
helpful!
Melanie L.

Hi Melanie,
In addition to the angle, your image shows the silver coloration
nicely.

(03/20/2006) unknown bug sitting on walls
Dear Bugman,
I'm glad that i found your website, i live in Spijkenisse,
The Netherlands and i keep on finding this bug in my house,
always sitting on walls, or running around in the bathroom.
For a couple of years now they seemed to be there. A few years
ago they where only half the size and only apeared in the
toilet and bathroom, always on concrete walls or floor. Now
they also appear in my bedroom. I've tried to catch one but
they are very fast. What i like to know is what this little
bug is, can you help me?
Kind Regards
Nick Dutrieux

Hi Nick,
Silverfish are common household pests that are generally found
in cool, damp, dark places, like the bathroom and under the
sink. They have a reputation for ruining books by eating the
glue in the binding.
Silverfish
(02/20/2006) Squirmies
Hi. I live in Michigan and was curious about this bug. I see
them in the bathroom sometimes along the crack between the
floor and the wall, they are very fast and hard to photograph,(I
had this one trapped for about a week hoping he would die
so I could get a picture). He is still alive although he did
change from brown to a very light color and is about 2.5 cm
long. Not as interesting as some of the other bugs you feature
but I wonder what this one is and if he changes into something
else. Thanks,
Melissa

Hi Melissa,
You have Silverfish, primitive insects and common household
pests that are usually found in dark damp areas.
Silverfish
(01/05/2006) What is this bug?
Hello bugman,
I found a few of these in my apartment. Can you tell me what
it is? Sorry for the blurred picture. It does not stay still.
This one is about 0.5cm but I've seen 1 mm to 1 cm in size.
Thanks much and have a wonderful New Year! From Toronto, Canada.

Hi Yoon,
You have Silverfish, a common household pest.
Silverfish
(12/20/2005) Whats that bug?
Hello bugman, I'm hoping you can help me.
I recently moved into a new apartment, and on the first night
spotted a cockroach in the sink. It was between 1 and 2 cm
long and was certainly a cockroach (no mistaking it). I had
my unit sprayed and did not see any adult cockroaches since
(its been about 4 weeks). I did however, find a strange smaller
bug (5mm-10mm) in the bathroom on 3 occasions over the past
2 weeks. Once it was in the tub, the other 2 times on the
floor. Each sighting was at night, however the bug did not
run from the light. My first guess is it is some sort of cockroach
nymph, as I've looked at pictures of cockroach nymphs and
they seem to share certain features (including a horizontally
striped body). On the other hand, the shape seems to be different,
and my bug seems to have some sort of long tail. Can you tell
me what my bug is? Is it a cockroach? I've attached a picture.
I suppose its hard to tell from the image but the bug was
relatively small.

Silverfish are primitive insects that like damp dark places
like your bathroom at night. They are usually regarded as
household pests and they will eat a large variety of organic
substances. They have a reputation for destroying book bindings.

(11/16/2005) silver fish???
I came across your site about a week ago and was trying to
find out what kind of bugs were the ones I kept on seeing
in my new apartment. Especially by the base of the fridge
and the nearby baseboards. I had just moved in and had never
seen such weird creatures...seemingly intelligent...but nasty
at first look, especially when they runaway soooo fast!!!
it's like roaches on speed or something...someone said they
could be Silver Fish...is that right??? What else do u know
about them??? and how do I get rid of them???? Also...can
they carry any diseases??? how big do they get???
if it doesn't swim why do they call it a fish??? I've enclosed
a close up shot of the BUG....along with a portrait with its
brother...or sister??? thanks for your help
Antonio

Hi Antonio,
This is indeed a Silverfish. They are among the most primitive
insects living today. They are so called because their bodies
are covered with shiny thick scales and also because of the
way they wriggle when they run. they are slippery and difficult
to catch. They feed on dry organic debris, and they eat paper
especially if it contains sizing or glue. They can do considerable
damage to books. They are not disease vectors.
Silverfish
(10/31/2005) What is that bug?
Hi,
I have seen this bug in our new apartment on many occasions.
I cannot figure out what they are. They are pretty small.
This is one is a little smaller than the head of a Q-tip.
They have been found mostly on walls, in dark places, and
more recently in the bathtub. Can you please help me
figure out what this bug is?
Thank you so much!

Hi Kita,
This is a Silverfish and most people would concur that they
are household pests.
Jumping Bristletails
(06/19/2005) Whats My Bug?
Hello!
I hope these photos will suffice - afraid I cant seem to get
a closer one. These little guys show up every time we put
the sprinkler on or when it rains.They are in our house -
as well as being all over outside. These little guys look
grey, but have a very pretty gold to them in the sunlight.
They are about 1/2 inch long. They are soft bodied and don't
seem to have a "shell". They like to jump - about
2-3 inches - when you disturb them. They seem to like darkness
and move a lot during the night. The top right photo is a
scan of the underside of the bug. The rest are digital pictures
taken with a webcam. I live in Williams Lake, British Columbia,
Canada, and I appreciate any insight you might have as to
identifying and controlling (read: keeping out of basement!)
these little guys. Thanks alot!
Christina

Hi Christina,
You have Jumping Bristletails, Family Machilidae, relatives
of Silverfish. They usually live under stones and leaf rubble.
Silverfish
(05/08/2005) What's the bug in the pictures called?
Hi,
We were wondering what the bug showed in the pictures
is called. We found it on a wooden fence in our
backyard. They scurried out when we banged on the
fence, and it was hard to catch them because they moved very
fast.
Thanks a lot,
Pranav & Prag

Hi Pranav and Prag,
We usually get reports of Silverfish from people with household
infestations. They are household pests that like damp dark
areas, usually basements and bathrooms. As yours is outdoors,
it is not really much to worry about. They are very primitive
insects.
Firebrat
(03/16/2005) What this bug?
Hello there,
I was wondering if you could help me identify this annoyance
in our household. I’ve had absolutely no luck with other
sites. I’ve attached a picture for you take a look.
Most of these bugs were sited by old heaters in our basement
apartment. Any help would be appreciated!
Thanks,
Rob

Hi Rob,
You have Firebrats, Thermodia domestica, a type of Silverfish.
It is a domestic species recognized by the mottled pattern.
It frequents warm and even hot places, often in boiler rooms
and near heaters. This habit leads to its common name.
Not Trilobites, but Silverfish
(09/05/2004) strange bug
Hi there, I'm from Edmonton, Alberta. I've found some
strange bugs in my bathroom and I have no idea what they are.
I don't have a picture, but they are about two centimeters
long, grey and they look almost exactly like trilobites (a
prehistoric crustacean extinct hundreds of thousands of years
ago) Here's a picture of what a trilobite looks like,
I hope it will help.
Carla
Thank you very much.

Hi Carla,
Since Trilobites have been extinct for millions of years,
we can eliminate that posiblility. Silverfish are one of the
most primitive groups of insects. They frequently are found
in bathrooms. I'm guessing that is what you have. They are
household pests which damage books.
Ed. Note: We just recieved this notice which
probably identifies Carla's trilobytes.
(01/16/2005) Carla & trilobites
Hi!
I used to live in Edmonton too and I can tell you that those
sure aren't silverfish. Carla has SOWBUGS. They are totally
harmless but really creepy, and they love to live in your
basement. They are also impossible to keep out of your home.
Here is a great link to information on the sowbug, which
is really a crustacean!

Silverfish
(06/30/2004) Bug in my house - Please help
Dear Bugman,
I am so glad that there is a site such as yours. I don’t'
know what I would do if I didn't find your site. I have a
critter in my house that just baffles me. I don't know what
it is and I have gone through the books in the library and
I just can't find out what it is that is living with me. It's
about an inch long from head to tail. It has antenna on its
head and the tail is like a tail of a fish or mermaid with
another set of antennas. It swings form side to side. At the
bottom, it seems to have multiple legs like a caterpillar?
I'm really not that sure, it just seems to slide on the floor.
Anyway, I find it on the walls, in my drawers in the kitchen,
bedroom, bath, on my bed… I can catch it pretty easily,
it doesn’t move too quickly, BUT it does have the capability
to slide right into the WALLS. When I kill it by smudging
it, it just seems to just flakes into pieces. I don't see
it all the time; I see one maybe every other day in a new
location. Would you PLEASE offer any information to see how
I can terminate it?

Dear S.,
You have Silverfish, a common household pest that is difficult
to erradicate. They are very primitive insects. They will
eat most anything, including the glue from book binding or
wallpaper. We have gotten a report that Cloves when spread
around helps to eliminate them.
(04/16/2004)
Ok, I noticed this bug now on several occasions, maybe you
can help. This insect appears to be roughly 1/8" to 1/4"
long, is kind-of silver-grey in color, and looks kind-of shiny.
Almost scaly. The tail comes to a taper. It just crawled back
into a crack in the back of the bathroom cabinet. My wife
and I have seen it them a few times now. I killed one by "flicking"
it with my finger, and it leaves what looks like the same
dusty stuff left when a moth is killed. A sort-of grey dust.
I am a fly-fisherman and am big into entomology and aquatic
insects, and these things are totally grossing me out. No
wings, antennae, did not hop or jump (at least not that was
noticed.
Please help. I don't know if this is nothing, or if I need
to get out a specialist. Since it may matter: I live in Michigan,
have noticed them over the past several months, and only in
the bathroom cabinet (source of moisture?) Plus, I think I
may have a small leak in the roof, and the cabinet would be
very close to where the leak would be (again, possible source
of moisture).
Thank you in advance. I looked for a while and couldn't find
anything at all, on your site or on the internet. Please Help!!!
Grossed Out Homeowner.
Dear Grossed Out Homeowner,
I am putting my money on Silverfish. These are primitive insects
and household pests which eat, among other things, the glue
in book binding and wallpaper.
(04/07/2004)Firebrats?
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.
Thanks!
Bob
Peoria, AZ
Ed.
Note: Several
hours later, Bob sent this email.
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.

SILVERFISH
DEAR WTB,
I HAVE SEEN SILVERFISH ALL MY LIFE AND HAVE BEEN TERRIFIED
OF THEM. I WAS TOLD BY MY
BIG SISTER THAT SILVERFISH WILL TRY TO BURROW INSIDE OF YOUR
EARS. IT THAT TRUE?
WILL THEY HARM PEOPLE IN ANYWAY?
SILVERCHICKEN
Dear Silverchicken,
I think your sister was pulling your leg. Earwigs,
on the other hand, have a reputation for seeking
refuge in ears, hence their name. Earwigs will
not burrow or do any permanent damage, they are just
seeking shelter. No need to fear silverfish or
earwigs.
(01/12/2004)
Hello I live in England and I was hoping you could help
me work out what the bugs I have in my lavatory are .They
are small brown ,worm like and they move by slithering along
the floor they remind me of silverfish the way they move
but are the wrong colour.
thankyou
Angela Thompson
Hi Angela,
Firebrats are close relatives of Silverfish and are brownish
in color. They prefer warm areas, and might be attracted
to the heat in your bathroom. They are similar in habits
to the silverfish, and are also household pests that feed
on starchy substances like book bindings, starched clothing
and wall paper paste.
(9/12/2003)
Cloves for (against) Silverfish
I have a note from some household tips mag that silverfish
don't like clove.
"If you are troubled with silverfish try placing whole
cloves in the closets and drawers."
dunno, but it's worth a try
I only have a couple in the bathroom and haven't found where
they live.
Wow, we love natural tips for pest control. We will
post this one immediately.
These
little things are ratherr shiny, jump great lengths compared
to their size. The one in the picture is about 1/4 inch long
- I've seen them up to about 1/2 inch. We had the house fumigated
for termites 8 weeks ago; these were among the earliest re-entrant
critters. Can you identify this thing?
Thanks, ... Al
Dear Al,
You have a Jumping Bristletail, Family Meinertellidae. They
are related to silverfish and are found in leaf litter and
in old stone walls. Some species invade houses. Most species
are nocturnal, abhor light and are secretive in their habits.
(4/8/03)
Are the legs of the silverfish poisonous? I highly doubt
they are, but my father in law claims they are.
Thanks,

Dear
Colin,
No the legs of silverfish are not poisonous.

Hi, I currently had the most unfortunate experience of discovering
a silverfish in my bathtub. It is one of two that I have
seen sense I moved in in November. My apartment is old with
steam heating and hardwood floors, So the option of dehumidifying
is not really an option. I have spent many frantic hour
on line trying to find out how to get these little darlings
out of my apartment. My problem is this ...I found much
conflicting info on them. Such as "there is no way
of truly eliminating silverfish" to "two silverfish
are nothing to worry about" and "silverfish will
not generally eat clothing" to "you should perchance
silverfish traps to put in your drawers" So what's
the deal? Any info you could give would help. I'm at a point
of hysteria (have you seen a yuckier looking bug) and very
worried about my clothing collection. Thank
you very much and also if moving away and starting over
is my only option at this point I'm okay with that.....:)
Steph
Dear
Steph,
Silverfish, which belong to the order
Zygentoma, are also sometimes known as firebrats because
of their love of warmth. According to expert F. Lutz, "If
such a creature is eating your wallpaper, starched clothes,
photographs or other belongings, your sorrow may be mitigated
by your interest in seeing the most primitive insect you
are likely to observe without special effort. Further damage
may be prevented by fumigating or by liberal use of fresh
Pyrethrum powder". If you move, be sure to not take
along any hitch-hikers. We once had a lengthy correspondance
with Miss Swanlund who was worried that her lovely Hollywood
starlet apartment was infested. She eventually moved, leaving
the vermin behind.
Are
pincher bugs the same as silverfish? And, are potato bugs
the same as earwigs?
Paleojenn1@aol.com
Dear
Paleojenn,
There are many things that
might be called pincher bugs, but silverfish (Order Zygentoma)
are not one of them since they possess no pincher like mouthparts,
nor any other pinching devices. They are small wingless,
primitive insects. Potato bugs or Jerusalem Crickets (Stenopelmatids)
are large, slow moving, burrowing members of the order Orthoptera,
and are related to other crickets. They are large, often
2 inches in length, and have a large head with strong jaws
that can deliver quite a smarting bite, but they are harmless
as they are not poisonous. Earwigs (Order Dermaptera) might
be your pincer bugs since they possess a dangerous looking
pair of pincers on the abdomen that look like forceps. They
are used by the insects to catch and manipulate prey as
well as to fend off enemies.
Another
successful identification!
Hello,
Yes, you are very, very right, because the photos on the
pages you sent me made my skin crawl while the others didn't...
Thank you very much for your help. It's nice to know what
they are finally. They seem to infest the majority of apartments
here in Chicago too, I've found them in three of the places
I've lived in (can they be transported by me or my furniture?).
One last question, I read from one of the pages that they
are good for eating things like silverfish and generally
indicate that there are other bugs they are feeding on.
Silverfish sound particularly horrible, so my question is
should I bother to try to get rid of them, or let them do
what they have to do and only kill the ones I see? Somehow,
even though their temperment seems harmless, they are the
nastiest bugs to me... like I said, they make my skin crawl
like nothing else and it takes me weeks to forget them whenever
I see one. Yuck.
Thank you again for your help.

Dear
What's that Bug,
Last night in yoga class, while
doing a spinal twist, I spotted a silverfish darting across
the floorboards very near my mat. I broke my pose, grabbed
a purple foam block, and squished the silverfish, leaving
its mutilated body on the gleaming hardwood floors. I have
two questions. First of all, is it bad karma to kill a bug
in yoga class? Also, is there any way that I might bring
an infestation back to my home?
Thank you,
Lethal Lotus
Dear
Lethal Lotus,
Though we here at What's That
Bug? are not practicing Buddhists, we are aware that it
is a Zen canon to think of ourselves as one with the universe,
and that includes silverfish. Can't we all just get along?
Was the silverfish harming you in any way? I would strongly
suggest that you do some karmic retribution.
Regarding your second question, to which former HomeBody
of the Month Miss Swanlund will strongly attest, once silverfish
become naturalized, they are nearly impossible for even
the cleanest homemaker to eradicate. The silverfish themselves
do not ascribe to the Zen way of life, hence they are interested
in overrunning homes and eating books with little thought
of how this might affect the human tenants. War is war.
Silverfish are notorious for seeking out cramped quarters
and crevices, especially those of the dark moist variety.
It is entirely possible to transport one of the wily critters
on your person, especially if it should somehow find itself
in an environment not conducive to its needs, like a brightly
lit room full of contorted bodies where the odds of getting
squished are high. It is also possible that one of your
fellow yoga enthusiasts transported the victim of your brutal
attack, and its siblings, to the site of your encounter.
(2/11/02) Hi,
I was restiching
a pair of pants yesterday when out crawled a strange looking
bug. It startled me and frightened me because I hadn't
ever seen anything like it before. It was no longer
than say 4-6 mm. It was basically yellow, but with
other colors on it. It had 2 "thingies" trailing
behind it. It was rather flat and narrow and moved fairly
fast considering it's size. I killed it so I'm going by
a 5-10 second memory recall. The pants are made of
100% polyester, from Guatemala. I realize that I haven't
given you much to work with , but if you can identify it
I'd be appreciative.
Thanks for your time,
Mrs. Irish
It sounds like the dreaded silverfish, a household pest
which will devour any and everything in the house. Sadly,
and much to our embarassment here at What's
That Bug?, the silverfish is our one big failure story.
As much as we tried, it seems we could never figure
out a way for Miss Swanlund, former Homebody
of the Month, to eradicate the pestilence from her tiny
and cozy Hollywood starlet apartment, forcing her to buy
a home and leave many of her prized books and possessions
behind.

Dear
Mr. Marlos,
I understand you are writing a column regarding BUGS for
AH. May I inquire for some information and advice before
the publishing date? Here is the problem. My home has (I
blush to admit) silverfish. They are relatively harmless
when it comes to my person, except that they upset me. But
I fear they are devouring my portfolio as well as books
and papers. Have you run across any way to rid my place
of them? My mother recommended silverfish bait, but I cannot
find any. It must be illegal at this point in time.
Miss S.
Dear Miss S.
Your fears are well founded. Silverfish (order Zygentoma)
are so called due to their shiny, scale-covered bodies and
their wriggling movements while running. They are often
found indoors, behind furniture and among books, and are
very difficult to catch. They eat organic debris and have
a taste for sized paper, often causing considerable damage
to books and wallpaper. They will also eat sugar, flour,
cereals and fabric material. These primitive insects like
dampness, and El Niño has provided an ideal habitat
for them this year. Though I have never heard of silverfish
bait, I can't imagine that your mother would be wrong. Perhaps
she can send you some via post. If that is not possible,
I would stock up on Raid.
