Silverfish in New Zealand

Silverfish are from the Family Lepismatidae and are white to brown-grey or bluish-silver in color. Silverfish are teardrop-shaped insects that measure up to 12-19 mm in length with three long bristles on their rear. They grow from egg to adult without visible change in appearance.

Silverfish - behaviour and habits

Capable of thriving in most climates, silverfish prefer to dwell in dark, damp areas such as basements, attics, kitchens and bathrooms. They are especially attracted to paper and damp clothing. Silverfish are commonly found in stored boxes in garages and sheds. Silverfish feed on carbohydrates, particularly sugars and starches. Cellulose, shampoos, glue in books, linen, silk and dead insects may be food sources and they have also been found in unopened food packages.

When Silverfish reproduce, they undergo love dances prior to mating - a bit like some humans! Males lay spermatophores, which are taken into the ovipositor of female specimens. Females' egg numbers and habits vary, depending on species. One species lays a few eggs a day where as another species lays clusters of 2 to 20 eggs.

Silverfish Prevention & Control

Silverfish are nocturnal, naughty and move very quickly. They are secretive, and the severity of an infestation may go unnoticed for long periods of time, allowing for exponential growth. Silverfish reproduce quickly. Silverfish are known for their destructive feeding habits, often ruining papers, clothing and wallpaper. They commonly infest dark, damp areas around paper and linen sources. Silverfish infestations can be found in kitchens, laundry rooms, bathrooms, attics and basements.

Silverfish can survive in almost any environment, but they prefer areas with high humidity. Nymphs develop faster in areas that are humid. Therefore, one of the best ways to prevent an infestation is to control humidity. In crawl spaces, open vents and in basements, use baseboards with caulking. Silverfish consume a variety of foods, and stringent housekeeping practices may help prevent an infestation by limiting potential feeding sites.

Signs of a Silverfish Infestation: Most often, homeowners detect silverfish when they find one on the floor or in a sink or bathtub. Their feeding damage also can indicate their presence, along with their tiny pepperlike feces.

However, if your home already hosts a silverfish population, hiring a professional who can create a customized approach is recommended. Traps and insecticides sold in stores will only kill individual insects and cannot address an entire infestation. Some people try to use cinnamon to repel silverfish from certain areas, but it does not kill the insects or their eggs.

Addressing a silverfish infestation requires treatment of both adult silverfish and their harborage. Most do-it-yourself remedies prove ineffective over time, with brief periods of relief followed by another infestation. There are a variety of silverfish traps on the market. However, these traps target individual insects and cannot prevent entire silverfish populations. Silverfish infestations require professional treatment.
