Silver Fish

Silverfish feed on most types of human food and appear to prefer starchy materials. They can cause extensive problems by damaging valuable books, photographs, paintings, plaster and other household items containing starch or cellulose. You will often find it’s the outer, shiny layer of photos that are most damaged.

Silverfish are nocturnal and discreet pest and infestations can go unnoticed for long periods of time until substantial damages have been done. They will also restrict their activities to relatively undisturbed areas such as bookcases, storage rooms and ceilings, where they may damage paper, fabrics and other materials.

In the Philippines though, silverfish can also survive in most environments due to the high humidity and can often be found in dark, damp areas such as kitchens, bathrooms, basements and attics.
