If you’re battling a silverfish infestation, there are a few ways you can go about killing them. You can use a combination of chemical and natural remedies to get rid of them.
One way you can kill silverfish is to create a barrier around your home. Block their access to food and water. Make sure the area around your home is free of clutter and that there is adequate ventilation.
Another option is to use a dehumidifier. Dehumidifiers work by drying out areas that are consistently wet. Silverfish are known to thrive in damp, dark places.
If you have a damp basement, you might consider putting in a dehumidifier. However, you should be careful to avoid adding more moisture to the environment.
One of the best ways to repel and kill silverfish is to add citrus fruit peels to your home. The citric scent of the peels will repel most pests.
Other options include sprinkling salt in areas where you notice the presence of silverfish. Essential oils can also be used to discourage the insects. For example, lavender or cedar oil are good repellents.
Boric acid is a simple and effective household cleaner that you can use to kill and eliminate silverfish. Sprinkle it around your home, including in the attic. However, you should be aware that boric acid is toxic if consumed by pets or children.
Another option is to apply a dusting of insecticide in storage boxes, light fixtures, and electrical outlets. However, this approach may not be suitable if you have a lot of clutter.
