How to tackle silverfish infestation and underlying moisture problems
Their presence 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 be a sign of serious moisture problems.
Moreover, while silverfish are harmless to health, they can cause damage in our homes by feeding on materials containing starch, such as books, wallpaper, or clothing.
They love humid places
Silverfish shimmer silver 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, and basements, and also near washing machines, dishwashers, or places with leaks.
High humidity is an ideal environment for silverfish, but unfortunately, it is also a condition conducive to the development of mould, wood rot, and the deterioration of walls, which can lead to serious and costly structural damage to the building.
The causes of excessive moisture can be varied. They often result 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 over time becomes a serious problem.
How to get rid of silverfish?
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.
