Vacuum the house thoroughly to remove silverfish eggs. Empty vacuum and promptly dispose of the debris.
Make a 50/50 mix of boric acid and flour,powdered sugar, or quick oats. Place the mixture in paper cupcake holders or old jar lids around the house. (This is great for ants too.)
Vacuum more frequently than usual for about 3 months as silverfish eggs can take up to 2 months to hatch.
