How to Get Rid of Black Slugs: 10 [Natural] Ways to Repel and Control These Pests

The black slug, also known as the European black slug or the black arion, is a large terrestrial gastropod mollusk in the family Arionidae.

This species is native to Europe but has been introduced to other parts of the world, including North America and Australia. They are considered pests because they feed on a variety of plants and can cause significant damage.

Slugs are soft-bodied, slimy creatures that can often be found in gardens and yards. They play an important role in the environment by decomposing dead plants and animals, but they can also be pests as they feed on living plants.

This pest can cause serious damage to gardens and crops as it consumes large quantities of food.

What is the black slug’s life cycle?

The black slug has a life cycle that goes through four stages: adult, eggs, juvenile, and adult. Adult slugs will overwinter either as adults or eggs. They will hibernate in the soil, under plant debris, or in mulch.

When the conditions are right in the spring, adults will emerge to start feeding and mating. The dormant eggs will begin to hatch, and the juveniles will grow into adults. Adult slugs lay their eggs in moist areas like under rocks, in compost, mulch, or soil.

These slugs lay eggs in the soil, and the eggs take about two weeks to hatch. The young slugs feed on plant roots, and the adults can lay eggs throughout the growing season, so multiple generations overlap.

Where do slugs come into your garden from?

Slugs come into your garden from dark, moist areas during the day. They are often drawn to gardens by the moisture and the darkness. You can help to reduce the number of slugs in your garden by making sure that you eliminate these conditions.

Though they are often out of sight, slugs come into your garden from a variety of places. They can migrate from other gardens or yards or even hitch a ride on plants and trees. You can also inadvertently bring them in on tools, pots, and other gardening supplies.

Slugs generally come out at night to feed on a variety of things in your garden. They can travel up to 1,000 feet from their original home in search of food, water, and shelter.

Therefore, they often go unnoticed because they come out at night and hide during the day, so many people are confused when they see plant damage that seems to have appeared overnight.

What do slugs eat in their diet?

Slugs are a generic garden pest that can cause a lot of damage to plants. They eat a variety of plants in their diet, but they prefer shady, moist areas where they can find plenty of food.

Slugs will eat anything, but they have certain favorite types of plants. Some of the plants that slugs like to eat are hostas, beans, squash, cabbage, lettuce, tomatoes, and seedlings.

– Fill with fresh beer before sunset

– Dump the contents of the trap into the compost bin – beer and all

If you’re using a reusable trap, just rinse it off and put some beer in it to bait the slugs. When you feel that the trap is full, dispose of it in the trash. If you’re using disposable traps, just throw them away when they’re full.

Alcohol (beer) free DIY slug traps
