Silverfish is not a fish; it is an insect, an Old World invertebrate belonging to the phylum Arthropoda of kingdom Animalia. Silverfish have a pair of antennae on their head, which assists them as a sensory organ in picking up motions and vibrations. These silver fishes occur in damp or moist areas in houses. Their occurrence is considered as a sign of either a dirty house or some other underlying problem. They feed on starch from the old books and newspapers and hence are considered very important decomposers. Belonging to the genus of Lepisma, a silverfish is scientifically known as Lepisma saccharina, where the species name saccharine originates from the word Saccharum or starch (sugar).

In order to get rid of a silverfish infestation, pest control and pest management are the only suggested solutions. Here are some of the most interesting facts about the silverfish insect for your perusal. Afterward, do check our other articles on huntsman spider facts and praying mantis facts as well.

How do they reproduce?

Silverfish breeds throughout the year in their suitable habitats. Before mating, they perform a ritual courtship display which is divided into three phases. These rituals last for over half an hour, after which the male deposits sperm in the female gonad. A female silverfish at a time lays around 60 eggs in the crevices of the house. After silverfish eggs hatch, larvae are born, wherein the nymphs resemble adults. They molt and develop a shiny metallic body. These juveniles turn into adults in the span of three months to three years after birth.

Are they dangerous?

These insects are very docile. They may cause infestations but are not dangerous. Silverfish bite is a myth as they do not bite humans; hence they are not really dangerous to live, but they do pose a danger to human property such as woods, fabrics, garments, paper, containers, and upholstery. They also do not bite pet animals. A sign of silverfish infestation is its droppings that are black and spherical in appearance, like pepper.

Would they make a good pet?

These insects are solitary, and also they are very small in size. They live in dirty areas and are not meant to be taken as pets. They live and breed in large numbers, and hence if taken as pets, they might escape and feed on all your stuff! Hence it is not advisable to take them as pets in any condition but rather get rid of them by using traps, insecticides, or any other suggested methods. While they are not poisonous, you must keep your cats or dogs away from this insect.

What are silverfish attracted to?

Silverfishes are found in old books, newspapers, and fabric. Since these materials are made up of sugars and proteins, the silverfish pest decomposes these into simple sugars and amino acids which they feed on for nutrients. You can have a silverfish in your house if there are areas with a lot of humidity or moisture, such as the laundry room or basement. These insects can climb up the bed as well.

How to get rid of silverfish?

There are a few ways one can use to get rid of silverfish pest infestation.

Get rid of old newspapers and fabrics. Make sure that there are no damp and moist places in the house.

Put up a container full of starch with tape on the outer surface in which the silverfish may crawl in and may not escape. Use essential oils or vinegar to repel these insects from clothes and books. Cleaning the hair thoroughly with a suitable shampoo is essential to get rid of silverfish in the hair. Avail of professional fumigation and pest control services to get rid of silverfish.
