Silverfish, small, wingless insects known for their shiny, grey or silver scales and long, narrow bodies, are appearing more frequently in UK homes this late summer. These creatures, which are about the size of a fingernail, are often described online as "unpleasant" or "little buggers" due to their tendency to invade homes. Their increased presence is linked to the current weather conditions, which provide the ideal combination of warmth and humidity for their survival. According to Paul Blackhurst, head of technical academy at Rentokil Pest Control, silverfish are attracted to dark, damp, and warm environments such as bathrooms, cellars, and attics. As the weather cools in late summer and early autumn, these insects tend to seek shelter indoors. September is often referred to as "silverfish season" because the combination of high humidity (over 50%) and mild temperatures creates the perfect conditions for their activity. While the British Pest Control Association (BPCA) states that silverfish do not bite humans or spread diseases, their presence can be a nuisance. These insects feed on starch and cellulose, which means they can damage household items like books, photographs, and clothing. One common sign of a silverfish infestation is the discovery of tiny, unexplained holes in these materials. The appearance of silverfish can also signal underlying dampness or moisture issues in a home. To prevent infestations, it is recommended to maintain cleanliness by vacuuming regularly to remove potential food sources such as dust and crumbs. Storing food in airtight containers and reducing humidity through ventilation, dehumidifiers, and fixing leaks can make a home less attractive to silverfish. Sealing cracks and gaps in walls and skirting boards can also help prevent them from entering. If an infestation is already present, over-the-counter sprays may help manage the problem. However, for more serious or recurring issues, it is advisable to consult a professional pest controller. These experts can apply targeted treatments to effectively eliminate silverfish and prevent their return.
