Gardeners often ask, “How do I get rid of slugs naturally?” since chemical slug killers aren’t just damaging to the environment, but also to your garden. Pesticides shouldn’t be used around edible crops since they may impact human health.

The most reliable ways to get rid of slugs naturally include: diatomaceous earth, encouraging predators, growing resistant crops, & adjusting the watering schedule. Setting up beer traps and installing borders of copper strips around plants will also reliably get rid of slugs.

There are several other methods for slug control too. Understanding how to apply the different slug control methods and how to save different crops against slugs is the key to ensuring there’s no further slug damage in your garden.

Slugs eat leaves, flowers, fruit and anything else that comes in its way.

Seedlings suffer the most damage when slugs visit them, decapitating them and leaving only stems sticking out of the soil.

If you’re tired of watching slugs and snails play havoc in your garden, it’s time to take action.

A combination of natural techniques are often used to get rid of slugs in the garden.

Sprinkling salt on slugs kills them but be sure not to apply too much salt to plants as it can negatively impact them.

Applying nematodes to the soil is also effective in getting rid of slugs.

These soil-dwelling microorganisms act as a parasite inside the slug’s body once they are consumed, paralyzing them and killing them eventually as a result of dehydration.

Nematodes need to be combined with water before applying to the soil, with the soil temperature being at least 41°F to work.

Slugs are a common existence in gardens at springtime.

Though getting rid of slugs once they appear is a time-consuming task, creating a garden that deters these creatures naturally is a much better solution.

One approach is to plant slug repellent plants around the garden, among your flower, fruit and vegetable plants to deter slugs.

There are many plant varieties, primarily those with a strong smell or prickly texture of leaves, that deter slugs.

Wormwood, fennel, anise, rue, and rosemary are some popular choices to keep slugs out of the area.

Additionally, planting white clover attracts ground beetles to your garden which are natural predators for garden slugs.

So growing clover around your garden can also help keep the slug population down.

While there are several kinds of slug-killing formulas available in the market, toxic pesticides aren’t good for your health if applied to edible crops, disrupt the beneficial wildlife in your garden and harm the environment.

Instead, many gardeners try to look for non-toxic, natural ways to keep slugs off their precious plants, causing little or no harm in the process.

An effective natural method for slug control is to apply some sort of natural slug-repellent around your most vulnerable plants.

Any prickly material, including crushed eggshells, diatomaceous earth, and pine needles make it hard for the slugs to crawl over.

Spread such material around the plant as a boundary to keep out the slugs.

While diatomaceous earth loses its efficacy when wet and will thus need to be reapplied after rain, this is not the case with eggshells and pine needles.

While sprinkling salt around the plants works in the same way, making it harder for slugs to crawl with prickly salt under their body, gardeners advise against creating salt barriers. 

When salt dissolves in the irrigation water or rain and seeps into the ground, it acidifies the soil, making it hard for plants to thrive or, sometimes, even survive.

How To Get Rid Of Slugs Organically

While it’s true that slugs and snails can inflict heavy damage on your garden, chemical control isn’t the only effective option to get rid of them.

Many non-chemical, eco-friendly techniques are just as effective and quick in getting rid of slugs.

If you live in a coastal region and seaweeds are easily accessible, you’re in luck with your slug problem.

A popular organic slug control method is to introduce seaweeds to the garden.

Seaweeds naturally repel slugs.

Create seaweed borders around the plants in your garden that are most susceptible to slug damage.

When these seaweeds dry with the sun, they become rough, preventing slugs from crawling over them with their slimy body to reach the plants.

Sprinkling sharp sand around the plants also repels slugs and protects your vulnerable crops.

How Do You Keep Slugs Off Strawberries Organically

How Do You Keep Slugs Off Strawberries Organically

If you find small, deep holes in ripe strawberry fruits, typically just under the cap, you’re most likely dealing with slugs.

Slugs are most active during damp weather, around the same time that strawberries start ripening.

If you don’t want to give away the bigger part of your beautiful strawberry harvest to these pesky creatures, it’s worth making an effort to keep slugs off the plants.

Remove leaves and other plant debris and mulches from around the strawberry plants to eliminate slugs’ ideal hiding spots.

Water deeply, but less frequently to prevent wet soil which slugs prefer to crawl over.

In addition, creating copper barriers around the strawberry plants is a very effective method to keep slugs off organically.

Copper interacts with the slime given off by the slugs’ bodies to create symptoms of the nervous system similar to an electric shock.

This unusual effect keeps the slugs away from copper bordering your precious strawberry plants.

How To Keep Slugs Out Of Your Garden

How To Keep Slugs Out Of Your Garden

The key to keeping slugs out of your garden is to make the area inhospitable for the pests.

Slugs like damp, dark places so make sure your garden has as little of these as possible.

Water the garden in the morning, so the soil has plenty of time to dry up before evening, when the slugs become active.

Remove mulch to prevent slugs from seeking shelter under them during daytime.

Rake the garden in early spring to get rid of plant debris and to expose slug eggs to predators.

All of these gardening practices will make your garden less attractive to slugs, ultimately helping in keeping them away.
