Do Slugs Bite? Debunking the Myth in a Nutshell

slug biting on a stem

When discussing the potential for slugs to bite, the answer is not entirely straightforward. While some species of slug possess rudimentary teeth-like structures called radula, they use these primarily for scraping and consuming vegetation. These radula are generally not strong enough to puncture human skin. However, there have been rare cases in which a slug bite has caused a burning sensation but that is an exception and not the norm.

It is important to remember that slugs are generally harmless creatures that pose little threat to humans. While the possibility of a slug bite cannot be entirely ruled out, the likelihood of one causing significant harm is minimal.

Common Misconceptions About Slug Bites

Slug Irritation or Allergic Reaction

One common misconception about slug bites is that slugs can cause skin irritations or allergic reactions. In reality, slugs do not have teeth or biting mechanisms to bite humans. Instead, the irritation people may experience is caused by the slug’s slime, which contains proteins that can cause mild irritation or an allergic reaction in some individuals. This irritation is usually temporary and can be easily treated by rinsing the affected area with water and applying an over-the-counter corticosteroid cream if necessary.

Confusion with Other Insect Bites

Another misconception about slug bites is that people often confuse them with bites from other insects, such as ants, mosquitoes, or spiders. This confusion arises because the symptoms of a slug’s slime irritation resemble the symptoms of insect bites in some cases. These symptoms can include redness, swelling, and itching.

To differentiate between a slug irritation and an insect bite, consider the circumstances in which the encounter occurred. If you were handling a slug or found one on your skin, it is more likely that any irritation or discomfort is due to contact with the slug’s slime. If you did not have direct contact with a slug, it is possible that an insect bite could be the cause of your symptoms.
