They're ba-a-a-a-a-a-ck! We've been without these things since
November. They reappeared a couple weeks ago when we had a warm
spell, so I'm assuming that they're coming from the attic - probably
through the recessed lights above the whirlpool that they seem to
favor. I've got a couple pounds of boric acid for this purpose, but
how do I get it into their space? I'd like to avoid climbing up into
the attic, particularly because I'm afraid of my reaction if I lift
the insulation and suddenly see a million of them scurrying for
cover. They're harmless, but in large numbers, they're really,
Silverfish love a moist environment. I knew that much so I googled
and this site has some interesting information. For one thing it says
to put the bait in the light fixture. I guess it would be easy enough to
get into there.
You won't be able to properly apply the BA dust evenly in the attic.
There is a boric acid bait from Dekko that is easy to use and would be
able to place where needed. Also placing a Prozap Pest Strip in the
attic above the main area of activity works wonders.
Silverfish are like cockroaches - they eat the refuse we leave behind. But
yes they also eat glue, paper, and anything loosely associated with
carbohydrates and starches. They drink the water we don't mop up - like the
stuff around the sink.
Keep a nice and tidy house, seal up the grains, flours, and other starches
and they'll eventually migrate back outside where they normally live. I
consider silverfish more of an indication that your house needs to be
cleaned than anything else. They're extremely common and utterly harmless -
except that they attract or support predators like centipedes and spiders.
Where are you? I'm in upstate NY and have had silverfish ALL winter long!
They are creepy, even if only one. They look leftover from the prehistoric
age. Someone suggested bait traps to put in the attic. I'm going to try
that. I hate any bug in my house. Do you ever see them in the basement?

Once silverfish make their way to the attic it will be nearly
impossible to get rid of them. They have plenty of food, a nice
insulation blanket to keep them warm and protect them from chemical
attack , and can reproduce faster than you can kill them.
I spotted some silverfish in my second floor bedroom a couple years
ago. Turns out that the source of these bugs were from the outside. A
small opening in the sill plate allowed them to enter into the
basement. There it seems they followed the electrical conduit drill
openings upward and exited out the baseboard on the second floor.
Plugging the opening in the basement stopped them. I believe that the
silverfish were living in the wood mulch around the house. I also
believe that they might have come in the mulch bags I bought earlier
that month. It is also probably not a good idea to store mulch bags in
the garage before using them. Store them outside.
If you can't kill them all, you have to contain them. Its a dirty job,
but go to the attic and find every hole that allow them to get into
your living quarters. Conduit drill outs seem to be especially good
pathways for them. Fill these openings with caulk, foam, or just
fiberglass insulation. You can also, in addition, sprinkle boric acid
powder around these openings.
Impossible to seal off EVERY light fixture, especially can lighting,
electrical plates, plumbing penetrations and baseboards in the home. Gas
water heater closets will have a ventilation cut through the ceiling
into the attic itself.
In NE Pa. I've not seen any in my basement, but the two upstairs
baths have had their occasional visitor.
I have a 5 year old, and if I don't vacuum often, I get every type of
creepy crawly in my house.
