According to Orkin, earwigs do not bite humans; however, the insects possess pincers for defense. The pincers can cause pain and may pierce the skin. If an earwig pinch breaks through skin, it is important to clean the area to prevent the spread of germs.
Premier Termite and Pest Control explains that earwigs are not considered dangerous to humans but can cause damage to outdoor gardens. The insects are typically drawn to decayed plant and animal matter, but certain species may also feed off of live plants and fruits such as strawberries and grapes. Earwigs seek shelter in dark, damp areas and can often be found in garbage cans, outdoor wood piles and mulch bins.
