Fact Files: Silverfish
What are those creepy little silvery bugs?
Scientific Name: Lepisma saccharina
Silverfish are primitive, wingless insects that measure about 2cm long, including the long tail filaments. The most common house species is covered with smooth glistening silvery scales, hence the name. They develop slowly under house conditions and can live for several months without food but typically live up to four years.
Silverfish appear to have no negative effects on agriculture or horticulture but can cause domestic damage eating foods or other materials that are high in protein, sugar, or starch. They eat cereals, moist wheat flour, glued paper, wallpaper and book bindings, starch in clothing, and rayon fabrics.
Silverfish are nocturnal, feeding at night, so they are not often seen by day.
The silverfish lives and develops in dark, damp, cool places, especially bathrooms and laundry rooms. Large numbers may be found in new buildings in which the masonry is still damp. Silverfish are often brought into new homes in cardboard boxes, books and papers from infested sites. Because silverfish need and seek moisture, they are frequently found trapped in sinks and bathtubs. They may also be found in bookcases, around closet shelves, behind skirting boards and window and door frames. Other likely places to find silverfish are areas of carpet behind and under heavy pieces of furniture and where the carpet extends into walk-in wardrobes. Regularly inspect these areas to keep on top of any possible problems.
