There has been a sharp increase in silverfish infestations in Ireland during the November-December period, with the insects seeking shelters indoors due to the colder climate.
New figures released by Rentokil show a 32% increase in the number of callouts for silverfish over the period when compared to the previous year.
Silverfish are nocturnal insects that are silver or grey in colour, measuring approximately 10-12mm in length with tiny scales and two antennae.
The insects can lay up to 60 eggs per day, so a small outbreak can quickly become a large one. Their eggs are usually difficult to locate, as they are often hidden in tiny cracks or crevices.
If left untreated, an infestation of silverfish can result in damage to books, photographs, paintings, plaster and other household items as they feed on both starch and cellulose. They also feed on human debris such as dead skin and hair.
A common sign to watch out for is finding unexplained holes in books or items of clothing.
Home and business owners are most likely to find silverfish in dark, damp, and humid areas such as bathrooms, basements and attics.
Due to the colder winter conditions, the insects seek warmth and shelter indoors which has led to the rise of infestations.
Dublin accounted for the most silverfish callouts (42%), while homeowners in Kildare (16%), Limerick (8%), and Cork (6%) also experienced issues.
Richard Faulkner, Advanced Technical Field Consultant for Rentokil said: “The most recent rise in silverfish callouts we have received is most likely a result of the cold weather. Like many insects, silverfish seek shelter and warmth inside homes and businesses during the wintertime. While these insects are not dangerous, they can become a major inconvenience because of their appetite for starch and cellulose, which can easily lead them damaging valuable items by feeding on them.”
Rentokil advises following these tips to reduce the likelihood of a silverfish infestation on your premises:
- 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.
