Have you ever seen a slimy creature crawling around your garden and wondered what it was? Chances are, it was a slug! These soft-bodied creatures are common in many parts of the world and can be found in a range of environments, from woodlands to gardens. In this article, I am going to answer some questions you might have about slugs, including whether they can be poisonous, how to handle them safely, and how to prevent them from invading your garden or home.
What Is A Slug?
What is a slug and what do they look like? Slugs are a type of mollusk, which is a phylum of invertebrates that also includes snails and clams. They have soft, elongated bodies without shells and are typically brown or gray in color. Slugs are known for leaving behind a slimy trail as they move, which helps them to navigate and stay moist. You might also notice pairs of antennae at the front of a slug’s body, which help them to sense their surroundings.
Are Slug Poisonous?
Firstly, it’s essential to differentiate between poisonous and venomous slugs.
Poisonous slugs are those whose skin secretions contain toxins that can cause harm when ingested or absorbed through the skin.
In contrast, venomous slugs inject venom into their prey or predators, typically via a stinger. While venomous slugs are relatively rare, poisonous slugs are more commonly encountered.
One of the most infamous poisonous slugs is the leopard slug (Limax maximus). These slugs can be found in Europe, North America, and Asia and often live in wooded areas. Leopard slugs produce a milky liquid that contains small amounts of toxins, which can cause skin and eye irritation in humans. While contact with this slug’s secretion is not typically lethal, it can cause discomfort and inflammation.
An example of a highly venomous slug is the blue-ringed octopus (Hapalochlaena), which is native to Australia, Indonesia, and the Pacific and lives underwater (no need to panic! You won’t find this slug in your backyard!!). This slug packs a deadly punch, as its venom is incredibly potent and can cause paralysis or death in humans. The blue-ringed octopus’s bright blue rings serve as a warning to potential predators to stay away. It is critical to avoid handling or coming into contact with this slug, as even a small dose of its venom can be deadly.
However, despite these two examples, the majority of slugs are not poisonous at all. In fact, most slugs are entirely harmless to humans. While some people may experience skin irritation or an allergic reaction to contact with certain species of slugs, these instances are relatively rare and usually not life-threatening.
There is also a common misconception that slugs secrete toxins to protect themselves from predators, such as birds or mammals. However, this is not entirely true, as slugs often use their slime to make themselves less appealing to predators or to facilitate movement.
Truth is, slugs play an essential role in many ecosystems as decomposers, and without them, the food chain could be disrupted.
How to identify a poisonous slug?
If you want to identify a poisonous slug, it’s important to look for specific markings or features on the slug’s body such as bright colors, slimy trails as some can indicate venomous slugs.
Next, observe the behavior of the slug. Poisonous slugs tend to move slowly and have a zig-zag movement, while other garden slugs move in a straight line. Slugs that try to climb plant stems or the sides of containers are more likely to be venomous than non-poisonous slugs, as the former is searching for prey or a place to hide.
An essential factor in identifying a poisonous slug is to pay close attention to the environment around you. Poisonous slugs thrive in moist environments like gardens and water sources. They tend to be active during the night and are more prevalent in the warm and humid seasons. If you notice a lot of salamanders or other amphibians moving away from an area, it might be because of potentially dangerous slugs.
How to safely handle a slug?
If you happen to see a slug that you believe might be venomous, do not touch it! If you need to handle a slug, it’s best to wear gloves or use a tool such as tongs. This will help you avoid any toxins it might be carrying. If you do come into contact with a slug, wash your hands thoroughly with soap and water. If you experience any symptoms such as skin irritation or breathing difficulties, seek medical attention immediately.
