An easier solution is to make small open packages, envelopes, of
boric acid mixed with chalk and place the packages in the display,
for a slow kill.  For faster results mix boric acid with substances
that are particularly attractive to silverfish they will come and
eat the boric acid and die.

In the US you can purchase boric acid at your local pharmacy. If
boric acid is not available at the drug store try a jewelers supply
house boric acid is commonly used as flux with hard/silver and gold
