House Fire !!!! It works every time.
I heard that borax works too. Boric Acid in trays....
Otherwise there are toxic sprays at your local hardware store.
Personally I'd rather have bugs than fill my home with chemicals, but
the boric acid is pretty safe for humans unless you got kids who will
eat it or pets.... In that case, maybe you can hide it. Silverfish
hide in old books and other paper. Put the boric near bookshelves.

Decades ago I lived in an apartment that had a bad case of silverfish (no
roaches, thank heaven). I laid down a good, healthy bead of the foaming
RAID along all the baseboards, and around the toilet and all the pipes that
came and went. Then I repeated it. The silverfish were about 99% gone after
that. I'd find the odd one here and there, mostly killing them, but the
masses evidently decamped to more friendly units.
My mother lives in a seniors' home that has cockroaches. She came up with
the very clever idea of placing masking tape in certain locations with the
sticky side exposed so that any crawlies must travel over it to get where
they're going. It works! The crawlies get stuck on the masking tape, where
they may be administered capital punishment at her leisure.
Silverfish seem to like to use water and sewage pipes as highways. Perhaps
you could try my mother's idea in the appropriate places.
Last time I saw silverfish I bought several cans of aerosol bombs and
set them all off at the same time at different places in the house
including the attic. Leave the house for a while after that. Never
saw any more silverfish after that. I have done the same for
cockroach infestations at a rental. Seems to work quite well.
