Silverfish are environmental indicators. Their presence  indicates a
suitable environment for them to breed some place in the building.
They are not necessarily living in the storage area but just
harvesting food there. For example they may be  living near some
plumbing where moisture occurs inside the walls or in an areas close
to where water is used. There are some base board sticky tapes that
have been used, also keeping storage containers off the floor may
also help.
