Lepisma saccharina

Scientific classification
Kingdom: Animalia
Phylum: Arthropoda
Class: Insecta
Order: Thysanura
Family: Lepismatidae
Genus: Lepisma
Species: L. saccharina
Binomial name
Lepisma saccharina
Linnaeus, 1758

Lepisma saccharina (commonly called the fishmoth, urban silverfish or just the silverfish) is a small, wingless insect typically measuring from half to one inch (12–25 mm). Its common name derives from the animal's silvery blue color, combined with the fish-like appearance of its movements, while the scientific name indicates the silverfish's diet of carbohydrates such as sugar or starches. It belongs to the basal insect order Thysanura, and the species is estimated to have existed for over 300 million years, originating in the Palaeozoic Era.[1] Often misidentified as a silverfish is the house centipede, another house-dwelling arthropod that exhibits rapid, fluid movement.

Diet

The favorite food of silverfish is any matter that contains starch or polysaccharides, such as dextrin in adhesives. These include glue, book bindings, paper, photos, sugar, hair, and dandruff. Silverfish can also cause damage to books, tapestries, and textiles. Silverfish will commonly graze in and around showers, baths, and sinks on the cellulose present in many shampoos, shaving foams and so on. Apart from these cases, the damage caused by silverfish is negligible and they have no direct effect on human health beyond psychological distress to those who are frightened or disgusted by their appearance. However, they also have a bite which may cause irritation but has no long term effects. Other substances that may be eaten include cotton, linen, silk and synthetic fibres, and dead insects or even its own exuvia (moulted exoskeleton). During famine, a silverfish may even attack leatherware and synthetic fabrics. In extreme cases, silverfish may live for a year without eating. Polysaccharides (sometimes called glycans) are relatively complex carbohydrates. ... Dextrins are a group of low-molecular-weight carbohydrates produced by the hydrolysis of starch. ...

Reproduction

The reproduction of silverfish has only recently been studied. The male lays a spermatophore, a sperm capsule covered in gossamer. Having located the spermatophore via a variety of biochemical signals, the female takes up the spermatophore for fertilization, which will then result in a fertilized egg.[citation needed]the young are white in color. A spermatophore is a capsule or mass created by males of various invertebrate species, containing spermatozoa and transferred in entirety to the female during sex. ...

Elimination

In buildings, silverfish can only exist in sufficiently humid, crevice-rich environments. If these two conditions are removed, the silverfish will not be able to survive. Other measures that may be taken to eliminate silverfish, at least temporarily, include the following: Humidity is the amount of water vapor in air. ...


Non-lethal

  • By far the most effective way to be rid of silverfish for sure is to keep an area or room tidy, limiting the possible number of breeding grounds they have.
  • Ensuring showers, baths etc. are rinsed clean and free of any residual toiletries that may attract hungry silverfish.
  • Leaving the bathroom door open after a shower to lessen the humidity
  • The scent of a sal ammoniac solution should drive away silverfish within 24 hours.[citation needed]
  • To capture silverfish, trap in small glass containers -- silverfish cannot climb up the smooth inside walls.
  • Silverfish can also be caught by sprinkling plaster on a wet white cotton cloth put in a corner overnight, near the silverfish's hideout.[citation needed]
  • Leaving a fingernail clipping (incidentally shaped similarly to silverfish) on the ground appears to ward them off.

  • It is important when filling crevices in which silverfish are living or may potentially live to use a filler material which is either toxic to insects, or does not contain materials which would supply the silverfish with a source of food.
  • A 1:1-ratio dispersion of borax or boric acid and sugar is a reliable bait to kill silverfish (relatively non-toxic to non-insects).
  • Adults can be killed by freezing, but it is difficult to kill the eggs.

Silverfish and Firebrats: Identification, Biology and Control - Harvard University (928 words)
Silverfish and firebrats belong to a very primitive group of soft wingless insects, evolving on earth even before the cockroach.
All silverfish and firebrats are vegetable eaters, some are subterranean or live in caves, and others are found in ant and termite nests.
The small dark feces of silverfish and firebrats are visible to the eye, and their scales can be identified with a hand lens.
Silverfish and Firebrats, HYG-2108-94 (1087 words)
Silverfish and firebrats eat a wide variety of foods, including glue, wallpaper paste, bookbindings, paper, photographs, starch in clothing, cotton, linen, rayon fabrics, wheat flour, cereals, dried meats, leather and even dead insects.
Silverfish and firebrats have flat, elongated bodies 1/3 to 3/4 inch long and broad near the head, tapering toward the rear-somewhat "carrot" shaped.
The silverfish adult is about 1/2 inch long with a uniform silvery or pearl-gray color, whereas the four-lined silverfish is about 5/8 inch long and the back displays four dark lines the length of the body.
