Home warning: Silverfish infestation signals hidden moisture issues

Silverfish in the house may signal a serious moisture problem within our four walls. Discreet and usually not causing fear, is the silverfish a reason for concern?

Silverfish, also known as fishmoths, are small, silvery insects that may seem harmless at first glance. Although they do not bite humans or spread diseases, their presence in the house can indicate significant moisture problems.

Moreover, silverfish, though harmless to health, can cause damage in our homes by feeding on materials containing starch, such as books, wallpaper, and clothing.

Silverfish's silver shimmer is due to tiny, shiny scales covering their bodies. These small, primitive insects love moisture. They feel most comfortable in places where the air humidity exceeds 75%. This is why they are most often found in bathrooms, kitchens, basements, near washing machines and dishwashers, or places with leaks.

High humidity is an ideal environment for silverfish, but unfortunately, it also promotes the development of mold, wood rot, and wall deterioration, which can lead to serious and costly structural damage to the building.

Excessive moisture can have varied causes. It often results from ventilation problems, leaky roofs, leaking pipes, or household appliances. Even a small oversight, such as ineffective bathroom ventilation, can lead to moisture accumulation, which becomes a serious problem over time.

Getting rid of silverfish is not easy, but the key to success is eliminating the cause, i.e., excessive moisture. Here are a few steps to take:

The first step is to improve ventilation. Make sure all rooms in the house are properly ventilated. Regularly airing out the bathroom and kitchen and using fans can significantly reduce the moisture level.

Remember to address any leaks. Check if the roof, pipes, and household appliances have leaks that could cause water seepage.

Get air dehumidifiers. Dehumidifiers help maintain the appropriate moisture level in high-humidity areas.

Various home remedies can deter silverfish. You can use cedar chips, cedar oil with water, cinnamon, or cloves. These natural substances can deter silverfish, though their effectiveness may vary.

In some cases, professional chemical agents or the services of a pest control company may be necessary. However, it is important to exercise caution, as some agents may be harmful to humans and pets.
