Silverfish
Silverfish are a small, wingless insect measuring normally 20mm or less in length. They have three tails or cerci and their body is covered in tiny silver scales. It's name comes from its silvery blue colour along with its fish-like appearance and movements.
Silverfish are commonly found outdoors under bark, rocks, leaf and plant compost, in soil and animal burrows. They also can live inside homes in dark, humid, crevice-ridden environments – especially bathrooms (take away these elements and it will not be able to survive). They feed on fungi and plant materials. In homes they like to feed on starch rich substances such as paper, book bindings, wallpaper glue and sometimes photographs.
