Be sure to treat outdoors around the perimeter of the home, especially around the immediate foundation, windows, doors, and eaves.
For silverfish, treatment of the attic (if one) and the closets is especially important. Niban Granules - http://www.epestsupply.com/product/NI... works well in attics, are resistant to summertime heat and will kill cockroaches and silverfish. Simply scatter it out in the attic, paying particular attention to eaves, etc.
Ants are a different story. Most ants have a particular habit or eat /feed on particular things, such as honeydew, aphids, etc.
Depending on the species of ant, spraying could make things worse. Especially in the case of carpenter ants. The only thing I recommend for ant control in which I don't know the species of ant is the KM Ant Pro and Gourmet Liquid Ant Bait - http://www.epestsupply.com/product/KM...
The KM Ant Pro will kill ants in almost every situation if given enough time. It replaces the ants natural food sources (sweets / proteins) and gives them a toxic dose of boric acid. The Ant Pro System will wipe out the entire colony and also help intercept new invading ants from outer areas.
