Snails and slugs
Is this a case of ‘to-may-to’ ‘to-mah-to’ or is there a difference between snails and slugs? Both snails and slugs belong to the phylum Mollusca and class Gastropoda. The class name is derived from the Greek word gastros and podos, meaning stomach and foot, respectively. This name is the simplest explanation of their biological structure. Their slimy, squishy bodies are essentially one giant stomach on a single foot. They travel by scooting on this muscular “foot.” This muscle continuously secretes mucus that facilitates their motion. Upon drying, it produces a silvery slime trail that indicates any pest’s recent presence. The mucus prevents their cells from losing moisture to the surrounding dry soil. This also saves them from being sliced open by sharp or pointed articles in the earth. The only difference between these two creatures is the fact that slugs are homeless!
Slugs are homeless snails!
Unlike snails, slugs do not carry a spiral shell or their ‘home’ on their back. This can be beneficial to slugs, as it allows them to squeeze into tight spaces. Unfortunately, it does leave slugs more vulnerable to their surroundings.
How Can I Stop Slugs From Entering a Flowerbed?
The best way to keep slugs out of an area is to stop them early in the season.
In the early spring, rake your flower beds and ornamental plants to remove leaves and other debris. This will also disturb and remove slug eggs at the same time.
Also work to remove any areas where slugs can shield themselves from the sun. Remove boards, flat rocks and other objects where slugs hide. Even large pieces of mulch can protect a slug. Likewise, don’t pile mulch more than 3 inches high.
An immediate option for keeping slugs out is to sprinkle diatomaceous earth around the border of the area. Slugs do not like to cross over territory covered with a rough or sharp texture that diatomaceous earth creates. An even better option is to sprinkle TERRO® Ant Dust around your ornamental plants. This will kill slugs and many other harmful plant pests, including ants, crickets, cockroaches, ticks and wasps.
Folk remedies suggest protecting your plants with a ring of crushed egg shells or sand, but this doesn’t work. In fact, snails appear to be attracted by the smell of eggs, and sand doesn’t bother them (unless they’re stuck in a desert). Coffee grounds and copper strips, two other commonly suggested folk repellents, don’t work either.
I Picked Up a Slug and Now My Fingers Are Slimy. What Do I Do?
While it may seem like a good idea to wash off slug mucus, don’t do it! Their mucus reacts with water, causing it to spread. Instead of washing it, rub your hand and fingers together. This causes the mucus to ball up (much the same way as rubber cement would), and it is then easy to pick off your skin. Once you’re satisfied that you’ve pulled up the slime, you should then wash your hands for sanitary reasons.
Is It Cruel to Put Salt on Slugs?
There are a lot of myths surrounding how salt kills slugs, some people say that they melt the slugs or that it causes instant death. These myths are not strictly true, salt kills a slug by dehydrating it.
Salt can kill a slug almost instantly, but it takes a great amount to do so, and it is still not instant, nor does it seem to be pain-free. Salt mixes with the slippery solution that coats a slug, this solution is extremely saline, meaning that it has very little water content.
Osmosis acts to fix this and masses of water are drawn out from inside the slug. This means that using salt to kill slugs is a long process that is very painful for the slugs.
As well as being quite cruel in nature, there is another reason why you shouldn’t use salt to kill slugs. Sprinkling salt on slugs, when they are outside on your plants, can damage your plants as well.
The increased salinity in the soil can prevent your plants from growing and sometimes even be fatal to them. Therefore, there isn’t much of a benefit to killing slugs in this way.
Salt does not belong in the garden and usually damages more than it helps.
Salt causes great harm not only to slugs and snails, but also plants and other, more beneficial creatures in the garden.
Killing collected slugs and snails with salt is not an appropriate method, as they die slowly and painfully.
Not only does this make for a gruesome sight, it is also highly questionable in terms of animal welfare.
However, one interesting possibility is to use salt in combination with double-sided tape to protect especially potted plants, at least for a certain time.
Why does salt kill slugs?
Throwing salt on a slug is one way of killing them. But why do slugs dry out and die when exposed to salt? The slugs die because of a process called osmosis, which occurs when a solution meets a permeable membrane.Advertisement
As you’re likely aware, slugs are pretty moist, sticky, slimy, water-filled creatures. The cells of its skin are extremely permeable, so when you sprinkle salt on a slug, it easily mixes in with the water that the slug continuously secretes.Advertisement
As the salt and water mix to create salt water, the slug will secrete even more water from its body in an attempt to dilute the salt water solution covering its body. If you use enough salt, the slug will secrete too much water and die of dehydration. This is why salt kills slugs.Advertisement

Does Salt Impact Other Garden Pests?
Slugs are not the only ones that have strong reactions to this substance. Here is a short list of some other pests that are affected by the presence of salt.

Ants do not dislike salt, on the contrary, they love the stuff. They will leave scent trails for the other ants in their nest to be able to navigate their way to the salt. Whilst you can use salt to act as a trap for the ants, the possibility of attracting these insects is something you should be aware of if you are planning on using it to deter slugs.
