Silverfish are a common pest species throughout Australia and prefer to eat items with a high starch content: cotton fabrics, silk, paper, glues, starch in book binding, some synthetic fabrics but they usually avoid woollens.
Silverfish are fairly harmless, but these silvery grey-blue, serpentine creatures aren't pleasant to have around the house. They feed on books, dead skin cells, and other starchy materials and thrive in dark, wet spaces.
You can get rid of silverfish by trapping them, repelling them, killing them with insecticides, or making your home less hospitable.
Description
- Silverfish are wingless insects with 6 legs and long antennae
- They are 8 - 10mm long, with a uniform silvery color over the top surface.
- Their bodies are long and slender.
- Silverfish are broad at their head with a gradual tapering toward their rear.
Problems
Silverfish prefer a dark quite environment and are most active at night. They prefer to nest in largely unused areas:- dusty roof spaces - storage rooms - wall cavities - bookcases - but they may roam extensively around a building in search of new food and moisture sources.
Although they cannot fly they move very quickly and hide in small spaces.
Silverfish require a large supply of starchy foods to survive. Silverfish diets are high in protein, sugar, or starch, including cereals, moist wheat flour, starch in book bindings, cotton fabric and paper on which there is glue or paste. (Old photographs are prone to silverfish attack.)
Management
The following house cleaning and maintenance steps will help to solve a silverfish problem and may eliminate the pests completely.
- Repair any leaky pipes or taps.
- Improve ventilation.
- Use a dehumidifier to reduce moisture in the air.
- Perform regular tidying, cleaning and vacuuming to remove silverfish eggs and crumbs, scraps of paper, debris, and mold.
- Remove any uneaten pet food.
- Clean under sinks.
- Don’t forget to clean crevices too, such as around the base of ovens and refrigerators and along baseboards.
- Fill any cracks that you notice.
- Seal any areas where wallpaper has become detached from the wall.
