 Slug Lives Matter

Slugs are part of Mother Nature’s clean-up crew; they return nutrients to the soil for the benefit of plants (and gardeners!). Here, some slugs feed upon, and thus recycle, a discarded corn cob.

Folks really need to change their attitude towards wildlife in their yards. Humans cannot exist on this planet without the organisms that do the jobs required to keep our environment running properly. Therefore, instead of constantly grousing about wildlife, they really need to learn to show more respect and gratitude for these critters.

 

Let’s look at an example from the Internet of a gardener’s complaint about slugs, and examine the poor “solutions” given by the garden columnist to address this complaint.

·    Gardener: “I, too, have been waging the war with the slugs over the years. I wouldn’t mind if they ate an entire leaf one at a time but they are like greedy slobs at a smorgasbord going from leaf to leaf nibbling a little bit out of each.” (Something to consider: No one would ever talk about people behaving “like greedy slobs at a smorgasbord”. Perhaps we’d think less badly of wildlife if we didn’t use name-calling for wildlife either.)

 

The garden columnist offered a list of Band-Aid solutions. Rather than addressing the underlying cause[s] of the problem the gardener is complaining about, his recommendations serve only to interfere with the proper functioning of the environment.

·     “Do not leave any decomposing plant material laying [sic] about.”

·     “Remove dead leaves promptly.”

·     “Cultivate your soil regularly.”

·     “Boards, rocks and stones can also make good hiding spots. Remove these if slugs are a problem.”

·     “Keep your lawn neatly trimmed. Slugs will often use tall grass as a hiding spot.”

 

One of the “jobs” a slug performs is that of recycling decaying plant and animal matter. This vital activity provides nutrition for your plants by returning essential components to the soil your plants are growing in. In other words, its activity feeds your plants so you don’t need to spend money, time, and effort applying chemical fertilizers.

 

Therefore, the worst thing you can do is to remove all decomposing plant material, including dead leaves, as advised in this published list. If you don’t leave a slug’s preferred food in place, it has no choice except to turn to your plants when it’s starving.

 

Now, if you are trying to “live in harmony with nature”, the point of the writer’s column, you are not supposed to be killing the organisms out there. And yet, the advice to “cultivate your soil regularly” is suggested for just that purpose.

 

Mixing up the soil regularly, either with a rototiller or a hand cultivator, chops up or otherwise injures critters within the soil, or exposes them to light and drying air that they are trying to escape by living within the dirt. Additionally, you might expose eggs that will either dry out in the sunshine or get eaten by predators, both of which negatively impacts the perpetuation of life.

 

The suggestion to remove rocks and stones that comprise a natural part of the environment because slugs hide there is not exactly living in harmony with nature either. And keeping your lawn trimmed so slugs can’t hide in tall grass is a very poor idea for the health of the grass itself. People cut their grass so short that it’s unable to grow longer roots to survive drought, and is also not even able to shade the ground to conserve moisture.

 

The last suggestion made by the garden columnist is the worst of all: “If these all fail, Safers Slug Bait is my go-to solution. It’s an eco-friendly product and targets the slugs without harming other organisms.” Whoa! This person could not have made a more egregiously wrong statement if he tried.

 

The active ingredient in this product is sodium ferric EDTA, which is also known as sodium ferric ethylenediaminetetraacetate.

It’s a salt that “works by interacting with and destroying hemocyanin, a copper-based compound found in the blood of molluscs [slugs and snails] and arthropods [insects, spiders, and both land and marine crustaceans; emphasis mine] which is used to carry oxygen.”

Therefore, this poison will kill any of the kinds of animals I’ve listed above within brackets, which is a far cry from being “an eco-friendly product [that] targets the slugs without harming other organisms”.

 

Mind you, Safer tells you that its product “[c]an be used around pets and wildlife”. Indeed, even Wikipedia tells you, “The compound is much safer than Metaldehyde and does not pose a significant risk to birds, pets, or humans so long as the bait is not consumed [emphasis mine].”

 

Well, it may be unlikely that humans would ingest this pesticide, but the likelihood is much, much higher for spiders, land crustaceans (pillbugs), and some kinds of insects to eat this substance. And I’d be very surprised if a bird wouldn’t pick up this bait and swallow it, either because it thought the bait was food or the grit it needs for grinding food in its gizzard.

 

It’s wise to keep in mind that pesticides are typically nonselective poisons that can kill far more creatures than you might expect. Why not create a nature-friendly garden that supports life on Earth instead of destroying it?

 

NATURE ADVICE:

 

You shouldn’t believe most of what you hear or read about pesticides. They are often described in terms that make them sound totally harmless, but since when is killing animals harmless? It’s cruel and inhumane to these organisms, which should be taken into account even if you don’t want them around.
