Silverfish are nocturnal insects typically 13–30 mm long. Their abdomens taper at the end, giving them a fish-like appearance.
The newly hatched are whitish, but develop a greyish hue and metallic shine as they get older.
They have three long cerci at the tips of their abdomens, one off the end of their body, one facing left, and one facing right. They also have two small compound eyes.
Silverfish are nocturnal so you may not see them during the day.
You will be able to spot silverfish presence because of what they leave behind including dark areas with small spots of excrement that look like black pepper or Small holes and yellowish stains on clothing, wallpaper, cereal boxes, and other cardboard or fabric materials
Silverfish are considered household pests, due to their consumption and destruction of property and are responsible for the contamination of food and other types of damage.
Silverfish consume matter that contains polysaccharides, such as starches and dextrin in adhesives.
These include book bindings, carpet, clothing, coffee, dandruff, glue, hair, some paints, paper, photos, plaster, and sugar.
Other substances they may eat include cotton, linen, silk, and may even attack leatherware and synthetic fabrics. Silverfish can live for a year or more without eating.
