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.

Spraying the site

Spray areas where silverfish are seen with Ant Stop! Gun (contains deltamethrin).
