Silverfish Control


Silverfish can live in most places, but they are attracted to dark, damp areas like basements, kitchens, bathrooms, garages, and attics. Since they are nocturnal and move very quickly, an infestation can go undetected for a long time. Silverfish feed on paper items, glue, clothing, and food such as flour and rolled oats. Since they thrive in high-humidity environments, we recommend considering a dehumidifier and repairs to any water leaks throughout the house.

If you’re treating your home for a silverfish infestation, you should prepare by doing the following:

  1. Throughout the unit, move all furniture away from the walls by about 12" to 18".
  2. Clear the floor area of all closets so that baseboard areas can be accessed.
  3. Remove everything from the lower kitchen cupboards (from the counter top down). Place these items on the counter or table. After treatment, do not wash the shelves, simply line them with new paper, either shelf-lining paper or wax paper before putting the dishes or food product back. This will provide a layer of protection between the pesticide and your dishes and/or food product.
  4. In the bathroom, remove everything from under the sink. These items can be placed in the bathtub. After treatment, do not wash the shelves, line them with new paper same as above.
  5. After treatment, everyone must be away from the home for a minimum of 4 to 6 hours. If anyone in the home is pregnant or nursing, less than 1 year of age, or having severe allergies or respiratory problems, these people should stay away for a longer period of time, generally 24 hours.
  6. All pets must be removed from the home for a minimum of 4 to 6 hours, except birds which should be removed for 24 hours. If you have fish tanks, you should cover the fish tank with plastic, a towel or a sheet and unplug any fish filters as they pump outside air into the water the fish live in.
