Identification and lookalikes



A silvery, scaly body is characteristic of the common silverfish. Firebrats are related but commonly mottled. Do not confuse either with a centipede, which has many pairs of legs along the body.
What silverfish eat
They can damage starchy materials, papers and some stored goods. Moisture, shelter and accessible food can support indoor populations. Different species tolerate different indoor conditions.
What to do next
To get rid of silverfish, inspect hiding places, fix dampness, reduce clutter and protect vulnerable papers and foods. Monitor activity before adding a pesticide; an occasional insect may only require physical removal.
