Do House earwigs bite?

Answered by John Hunt

House earwigs, also known as Forficula auricularia, are small insects that are commonly found in homes and gardens. They have a distinct appearance with elongated bodies and pincers on their abdomen. These pincers, also known as cerci, are often the cause of concern for many people. While earwigs do have pincers, they are not used for biting humans.

The purpose of the pincers on an earwig’s abdomen is primarily for defense and mating. When an earwig feels threatened, it may use its pincers to pinch in order to protect itself. However, it is important to note that earwigs are generally not aggressive towards humans and will only resort to using their pincers if they feel cornered or provoked.

In terms of actual harm, a pinch from an earwig can be uncomfortable and may cause a small amount of pain, but it is unlikely to break the skin or cause any lasting damage. The force of an earwig’s pinch is relatively weak compared to other insects, such as ants or wasps. So, while it may startle you, it is unlikely to be a cause for significant concern.

It is worth mentioning that there are over 2,000 species of earwigs, and not all of them have pincers that are as pronounced or noticeable as the common house earwig. Some species may have smaller or less developed pincers, while others may have none at all. Therefore, the potential for pinching may vary depending on the specific species of earwig.

If you do happen to come across an earwig and are concerned about being pinched, it is best to simply avoid handling or provoking the insect. If you need to remove an earwig from your home or garden, it is recommended to use a gentle and non-aggressive method, such as using a piece of paper or a container to capture and release it outdoors.

While house earwigs do possess pincers on their abdomen, they are not known for biting humans. The primary purpose of these pincers is defense and mating. While a pinch from an earwig may be uncomfortable, it is unlikely to cause any significant harm. So, there is generally no need to fear or be overly concerned about being bitten by an earwig.
