The method described involves:
- Filling a glass jar with oatmeal.
- Wrapping the outside of the jar with tape to create a climbing surface.
- Leaving the jar overnight in areas where silverfish are active.
The starch in the oatmeal attracts the insects.
Once inside, the smooth glass surface makes it difficult for them to escape.
3. Treat Visible Nesting Areas
If a concentration of silverfish is discovered in a particular area, some homeowners use ethyl alcohol as part of their cleaning routine.
Always follow manufacturer safety instructions and use products only as directed.
Because alcohol is flammable, proper ventilation and careful handling are essential.
4. Reduce Moisture in Your Home
Controlling humidity is one of the most effective long-term strategies for reducing silverfish populations.
Silverfish depend heavily on moisture for survival.
Helpful steps include:
- Repair leaking pipes.
- Improve bathroom ventilation.
- Use exhaust fans regularly.
- Open windows when possible.
- Reduce basement humidity.
- Dry wet surfaces promptly.
5. Use Baking Soda to Absorb Moisture
The original tip suggests placing baking soda in problem areas to help absorb excess moisture.
While it is not a direct treatment for silverfish, reducing humidity may make the environment less attractive to them over time.
