More disconcerting than damaging, silverfish are quite common in houses. They tend to congregate in moist conditions – and you'll often see them in the bath or in sinks.
Silvery in colour, silverfish are about 13mm (0.5in) long, thin and with fine antennae at the front and three tail-like appendages at the back.
Silverfish appreciate damp, humid conditions and so are often found in kitchens, larders, bathrooms and behind loose wallpaper, as they readily eat gums and glues.
Treatment and Control
Try to reduce condensation and the damp conditions in which silverfish thrive.
Several insecticides are approved for use in the home to control silverfish.
