The number of callouts for the nocturnal insects silverfish surged during winter, pest control provider Rentokil has said.
November 2021 to January 2022 saw a 79% increase in callouts due to the insect compared to the same time the year before, with 52% of infestations in Dublin.
Silverfish are nocturnal insects that are silver or grey in colour, measuring approximately 10-12mm in length with tiny scales and two antennae and have a tapered, tail-like appearance.
The insects are likely to be found in dark, damp, and humid areas such as bathrooms, basements and attics.
Rentokil have warned that silverfish can lay up to 60 eggs per day, so a few insects can quickly result in a much larger infestation.
They said their eggs are" usually difficult to locate", as they are often hidden in tiny cracks or crevices.
The bugs feed on both starch and cellulose so infestations can result in damage to books, photographs, paintings, plaster and other household items.
They also feed on human debris such as dead skin and hair.
Rentokil said a common sign your home or business may be infested with silverfish is finding unexplained holes in books or items of clothing.
They also gave the following tips on how to avoid an infestation:
- "Deny them food by vacuuming and keeping dust and debris to a minimum.
- "Store food in containers with tightly sealed lids.
- "Homes and businesses should also dehumidify their premises through the use of fans, dehumidifiers, or by opening windows to air them out.
- "Make sure all cracks in walls and skirting boards are filled."
Richard Faulkner, Advanced Technical Field Consultant for Rentokil said that silverfish aren't dangerous but can lead to damage of household items.
"Like many pests during colder periods of the year, silverfish move indoors to seek shelter and warmth inside homes and businesses.
"While silverfish aren’t dangerous, they can become a major inconvenience because of their appetite for starch and cellulose, which can lead to them damaging valuable items by feeding on them."
