Silverfish (scientific name: Lepisma saccharina) are discreet insects that are harmless to human health, but they can cause minor problems in homes, libraries, offices and other environments. Despite their small size, silverfish (also known as silver bugs) have curious habits and a feeding preference that can damage objects such as books, papers and fabrics.
In this article, we will explore what silverfish are, their habits, and the most common places where they can be found. If you have an infestation of these, learn about the best products to eliminate silverfish.
What are Silverfish?
Silverfish are small insects with flat, elongated bodies, belonging to the order Zygentoma. Their popular name derives from their silvery appearance and shape, which resembles a miniature fish.
Main Features:
Size: They measure 8 to 12 mm when adults.
Color: Silver or grayish, with metallic reflections.
Body Shape: Elongated and flattened body, with small scales that give it a shiny appearance.
Movement: Fast and similar to that of a fish swimming, which also justifies the name.
Most Common Places Where They Are Found:
Silverfish prefer dark, humid environments with little air circulation. These factors provide the ideal environment for their reproduction and survival.
1. Houses and Apartments:
- Bathrooms: Humidity and heat make bathrooms ideal places.
- Kitchens: They can be attracted to food scraps, crumbs and sugar.
- Attics: Dark, poorly ventilated environments are perfect for their proliferation.
2. Libraries and Offices:
Silverfish are notorious for infesting libraries and offices due to the abundance of paper and glue. Old documents, books, and cardboard boxes are favorite haunts of these insects.
3. Warehouses and Depots
Places where there is an inventory of materials such as paper, fabrics and packaged foods can attract these insects, especially if the humidity is high.
4. Cabinets and Drawers
Clothes stored for long periods and natural textile materials (such as cotton and wool) can be damaged by silverfish.
5. Structural Spaces
Gaps in skirting boards, cracks in walls or false ceilings are common hiding places for these insects, allowing them to move around unnoticed.
Signs of Infestation:
Silverfish are small and active at night, which can make them difficult to spot. However, there are a few signs that may indicate their presence:
- Small holes or irregular marks in paper, fabrics or stored food.
- Shiny scales left where they move.
- Direct viewing in humid environments or when moving old objects.
