How to control a silverfish infestation

The Silverfish (Lepisma saccharina) is a nocturnal invertebrate who enjoys foraging in kitchens and bathrooms. During the day, silverfish hide behind bath panels, skirting boards and wall paper. Indeed, any small crevice provides a secure hidey-hole for this little creature. So, in order to learn how to control a silverfish infestation, we need to gain an understanding their behaviour and movements.

Silverfish: Distribution and Habitat

Silverfish are found throughout the world. Indeed, they are closely linked with human activity. They favour the following parts of your home:

  • Bathrooms
  • Kitchens
  • Pantries 

Therefore, these are the areas where you should focus when you are trying to control a silverfish infestation. Ironically, silverfish cannot escape from areas with polished or shiny surfaces. So, you will often find the little creatures trapped in sinks, baths and china. 

The biology of silverfish

The adult silverfish is a silver grey wingless insect. The adult has long antennae and three tails. The female lays up to 90 eggs in foodstuffs and food storage areas. The nymphs take around one year to fully develop. The adult silverfish grows up to 20mm in length and it is conical in shape.

The impact of Silverfish infestation

Silverfish, on the whole, are a harmless home invader. So, why should you control a silverfish infestation when they do not spread disease or infection. Unfortunately, however, they do damage manuscripts, papers, textiles and dried food packaging. Moreover, they enjoy feeding on the protein filled gums and binding pastes found in fine textile and leather products. In addition, this insect will invade packets of dried food that have been stored in damp pantries.

How to control a silverfish infestation

Silverfish in small numbers do not pose a significant problem. Unfortunately, trying to control a larger silverfish infestation is difficult. Books, papers and manuscripts can be stored in a dry environment. However, it is difficult to reduce humidity levels in kitchens and bathrooms. The installation of an effective dehumidification system is the only option.

The do it yourself approach

When it comes to controlling a silverfish infestation, there are a number of organic pest control options:

  1. Cedar. Silverfish are repelled by the smell of cedar oil and cedar wood shavings.
  2. Cinnamon. Place ground cinnamon, cinnamon sticks or cinnamon oil in infected areas.
  3. Citrus fruit. Silverfish are repelled by the scents of orange or lemon peel. In addition, a spray of lemon juice and water can be used on the infected area.
  4. Cucumber. Silverfish do not like the smell of fresh cucumber peel shavings.
  5. Cloves. The clove contains eugenol which is a natural insect deterrent.
  6. Salt. Silverfish are attracted to, and enjoy eating, salt. Unfortunately, for the silverfish, eating salt will cause them to dehydrate and die.

There are harsher silverfish infestation pest control treatments that are available over the counter.  There are a variety of liquid spray formulations available that will eliminate silverfish. However, proceed with caution because these formulations are poisonous and toxic. The ingredients may be harmful to children, pets and adult lungs if inhaled.

Moreover, there is a good chance that the infestation will not be eradicated. The homeowner will probably not have the necessary equipment or expertise to achieve a blanket coverage of the infected area.  In addition, personal protection during silverfish pest control is of paramount importance.  

The importance of PPE

In order to control a silverfish infestation, Personal Protection Equipment should include:

  • Protective clothing. All in one pest control suits are freely available online. Usually, these suits are disposable and they can only be used for one pest control application. However, if the pest controller requires more comfort and repeated use, a double thickness, breathable suit would be the best option.
  • Eye protection. Pesticides may get into the eyes in any situation where spraying or fogging is involved.
  • Masks/respirators. In order to limit the absorption of pesticide vapours, fumes and other unwanted particles a respiratory mask should be worn.
  • Gloves. Gloves will protect the hands from pesticide contact and injuries during spraying. Furthermore, there should be no gaps between the gloves and the protective clothing.
  • Shoe protection and safety boots. Foot protection is important during spraying and to prevent insecticide spills damaging your feet.
  • Helmets. A safety helmet is mandatory in any environment where chemicals are being used and there is the possibility of falling objects.
  • Ear protection. Ear muffs not only protect the ears from excessive noise but they prevent unwanted particles from entering your ears. 

Vital human organs are at risk of damage if the correct Personal Protection Equipment is not used.
