If you live in a climate that’s even the slightest bit rainy or wet, then you know all too well about slugs and snails and the damage they can inflict on a garden.
The wetter, rainier and more temperate your climate is the more likely you are to have an issue with slugs. Slugs like to hide in moist, dark, shady spots in the daytime and then come out in the evening, rainy days and through the night.
They’ll come out in the daytime too if it’s cool and wet enough. They have a voracious appetite for your garden. You’ll need to have an attack plan in place to defend against them.
What to do and how to combat them is always the question for many gardeners.
Slugs and snails are similar creatures, both in the Mollusc family, and can essentially be treated the same when it comes to control and eradication of them.
They love Hosta, Lilies, Strawberries, Marigolds, Delphinium and so many plants that we usually have in the garden. They’ll eat almost anything.
For your attack plan, you can choose from a wide variety of remedies ranging from barriers to deterrents to poisons and traps.
They can all help you deal with the slimy little icky creatures. If the slugs live in a favourable environment, slugs can reach 6″ – 8″ long. Over the years they have destroyed hundreds of pounds of my garden and harvests. I’m not a big fan of them.
Strategies and Solutions
Thankfully, we have several options when it comes to getting rid of them.
At one point in the past, I was told to put Marigolds all around my garden because they repelled slugs. I planted them in front and all around my lilies in the early spring as soon as I could get them from the stores.
Well, it did work, but not quite as planned. The slugs loved and devoured my marigolds!
So in the end, the slugs stayed off my Lilies, which is ultimately what I wanted but the Marigolds became a sacrifice but still acted as the barrier they were originally intended to be.
Corry’s metaldehyde powder works well but you need to make sure your domestic pets don’t get into it. It’s a true pesticide.
Use it every week or so throughout your rainy season, depending on how fast the powder deteriorates. By doing this you will kill all the upcoming generations of them and not have an issue.
Iron pellets present as Ferric phosphate is the best option if you don’t want to use chemical pesticides. The iron is a natural element found in soil, so the uneaten bait just gets absorbed into the soil.
When the slug or snail eats the iron they immediately stop eating, which instantly stops them from destroying your garden. They will then crawl off to die within one week and there is no mess to clean up.This type of slug bait is what currently use in my garden.
The slugs are attracted to the yeasty sweetness of beer or ale. Don’t use lager, it doesn’t work. They are attracted to the trap, they drink the beer, they fall in and drown. That’s it.
You’ll need to empty it of the bodies everyday and put in new beer. Designs such as this sunflower pictured here are very effective. If you do this consistently you will have a huge impact on their population and greatly reduce their numbers.
Copper Mesh or Copper Tape
Copper works by creating a little electric shock on the underside of the slugs and snails. The idea is that they will be less likely to cross the barrier.
Copper can be expensive and it loses its power after a while and eventually doesn’t shock the slug.
Along the way I’ve heard that it’s possible to use your own hair from your hairbrush or use the hair from your dog or cat after your brush them.
Make a barrier of this and they slugs will not have an easy time crossing that because the hair gets stuck in their slime.
However, personally I’m not so sure I want clumps of hair all over my garden.
Ground up eggshells are very sharp and uncomfortable for the slug to crawl across. They will be deterred by a wide barrier of eggshell around your plants, containers and garden area.
The eggshells have sharp edges and the slugs will choose an easier path first before they choose to go across the sharp barrier to your yummy strawberries.
This one works but you need to keep the eggshells fresh and the barrier unbroken. Re-establish your barrier after a heavy rain or if it gets kicked or disturbed in any way.
But also note that this method does not consider the slugs that are already living within the boundary you set with your ring of eggshells.
Ducks love to eat slugs and slug eggs! If you don’t own any yourself, do you know someone with a farm or who owns a few ducks? Ask if you can borrow them for a few hours here and there over the summer.
The ducks will get some bonus ‘free range’ time when they visit your garden and they get a to have a yummy snack of slugs and slug eggs at the same time. They root up the eggs with their bills and eat the adults in one gulp happily.
This duck method of dealing with the slug issue works well but they do require some control.
They have the capability of eating your plants and causing some damage to young seedlings when they walk around. They tend to trample more than they walk.
If your garden is small then only leave the ducks out there for a little while at a time, maybe 10 minutes at a time, but keep an eye on them. Once they run out of slugs and slug eggs they will turn their attention to the plants in your garden. Take them out of your garden when you notice them turning their attention from the slugs to the plants.
If your garden is large, then they can stay out there for longer each time but still keep an eye on them. This method only works with ducks, don’t use chickens, geese or turkeys.
Leave a comment and me know what you do to get rid of the slugs you deal with.
Thankfully slugs are easy to control with consistent effort to control them such as the suggestions listed above. The best part is that your garden will quickly recover after the removal of the slugs and start thriving and blooming again.
If you employ even one of these methods of slug control you will likely see a great reduction in their numbers and much less damage to your garden. It’s best to use a couple of the methods in conjunction with each other to see the best results.
If you live in a wet climate then you will always have slugs and snails but knowing what to do about them is key. Your garden will be saved and free to happily grow all season long without the threat of any more slug or snail damage.
