Managing silverfish infestation

Did you know that silverfish eat clothing, books, wallpaper and our own food?

While they’re not usually as dreaded as spiders or cockroaches, silverfish are still a nuisance that many homeowners have to deal with every year. These little crawlers won’t spread germs or bite you, but they can really be a pain in one’s life as they create damages in our personal belongings and homes.

Silverfish feed on any carbohydrate they can find. This can result in damaged wallpaper, fabrics and clothing, and almost anything containing starches or glues. They can cause extensive damages to the valuable books, photographs, paintings, plaster and other household items containing starch or cellulose. They also cause yellow stains, lowering the value of your home.

Silverfish lay eggs all year round unlike most pests.

Silverfish get their name from the insect’s silvery, metallic appearance and fish-like shape, long thread like antennas and movements. Silverfish are found throughout the U.S. and are typically seen in moist, humid areas in the home, such as living rooms, bedrooms, bathrooms, basements and attics, garages and shake roofs.  In fact, shake roofs are excellent breeding sites for silverfish during the warmer months, as there’s an abundance of moisture, cellulose, starch and dead insects. From there, they can easily gain entrance and move down through the insulation to enter a structure.

Silverfish are also known to infest commercial structures such as offices, stores and libraries.

These nocturnal and delicate pests which can cause an infestation to go unnoticed for a long period of time until substantial damages have been done.

Father’s fury at housing association after a year living in a silverfish infested Westbourne flat

Daily Echo │2nd October 2018

Kamil Sahin and his 10-year-old daughter Cemo have been left disappointed by the way Spectrum has dealt with their issue.

Just last week Cemo was shocked to discover a living silverfish inside a dictionary she was using for her school homework.

“It makes me feel sick,” she said. “If an engineer came here and lifted up the carpet I think they would find hundreds of silverfish.”

Mr Sahin said the silverfish are seen on a daily basis.

Irish homes are being invaded by pesky silverfish insects

The insects can live up to three years and thrive in damp conditions

By Edel Hughes ; Irish Mirror │February 21, 2018

Irish houses are being invaded by pests, with the inclement weather creating infestations of silverfish insects in our homes.

Pest control company Rentokil reported a 171% increase in the numbers of callouts about the small wingless insects in January 2018, compared to the same period last year.

They say infestations of silverfish could be down to the damp conditions the country has experienced, as silverfish thrive in cool, dark and moist areas.

The critters, which can live for up to three years, love bathrooms as they can feed on dead skin, hair and even shampoo.

Insecticides and some biological control practices are being implemented but these are proved to be ineffective.

We need a solution that is effective, eco- friendly and easy to use.

The unique product Combirepel™ manufactured by C Tech Corporation is an anti-insect aversive which repels insects.


Combirepel™ works on the mechanism of repellency. It temporarily inhibits the mating cycle of the insects. The product impairs the ability of the insects to reproduce, that is the insects will not lay eggs or the laid eggs will be infertile. The product causes feeding disruption in an insect by triggering an unpleasant reaction within the insect which might try to feed on the application.

The product temporarily blocks the reproduction system of the insects by hindering the release of the vital hormones for growth.


Combirepel™ is an extremely low concern, low toxic, low hazard, non-carcinogenic and non-mutagenic insect aversive. It does not kill or cause harm to insects as well as to the environment which indirectly helps to maintain the ecological balance.

The product available in the form of liquid concentrate can be mixed in paints in a predetermined ratio and be applied on the interior and exterior of the buildings and structures to keep the silverfish away from these places.

The product is also effective against other pests thus protecting the trees from other pest attacks.


Combirepel™ s available in the form of the masterbatch, which can be incorporated into the polymeric applications like polymeric wires and cables, pipes, etc.
