I hate slug pellets, I would never use them, not even the organic kind, slug pellets are incredibly detrimental to wild life killing lovely hedgehogs (a natural predator of slugs and snails) in a horrid, drawn-out and painful way. If like me, you want to want to protect our wildlife and help preserve the natural balance of nature, there are many ways you can protect your precious plants from slugs and snails.
Slugs and snails are fleshy, succulent beings, they have a protective slimy layer which also enables them to move around, and they don’t want to cross anything that’s sharp or abrasive or will dry out this protective layer. So by using sharp sand, course grit, sawdust, ash, soot, crushed eggshells, and diatomaceous earth as barriers around your plants you’ll naturally be deterring slugs and snails. Human hair and horse hair are also excellent at keeping slugs and snails at bay, as is garlic granules or garlic wash – these two will need to be reapplied after any wet weather, pine needles and copper tape can also be used, there really are so may effective natural remedies you can use. You can also purchase nematodes – naturally occurring microscopic predators of slugs and snails used in a concentrated form, and very effective at controlling the types of slugs living in the soil, so they are very effective if Keeled slugs are eating your potatoes. Nematodes are very effective in wet weather when many remedies fail. Slug nematodes aren’t as successful in areas where manure is used as a fertiliser, so do bear that in mind.
Please do remember that all of these deterrents will need to be regularly reapplied and in the case of the copper rings and tape, regularly rubbed over with sandpaper to keep the surface fresh and free of oxidisation.
Here are some other natural predators of slugs and snails: frogs, slow worms, shrews, ground beetles, centipedes, Marsh flies, newts, ducks and chickens. Garden birds, especially Song Thrushes, Mistle Thrushes and Redwings are natural predators of slugs and snails, eating them all year round, these birds have declined dramatically since the introduction and widespread use of slug pellets, hedgehogs have also declined significantly, let’s do more to help these wonderful creatures, by stopping using slug pellets and making our gardens more wildlife friendly!
Garlic Wash Recipe
To make garlic wash; take two bulbs of garlic and crush the cloves, place the crushed garlic in two pints of boiling water and boil for a few minutes. Leave the mixture to cool, then strain it and bottle. To use garlic wash: dilute one tablespoon of garlic wash to a gallon of water; apply by watering over your plant’s leaves on a dry day. Garlic wash is very effective, but only in dry weather, once it rains you’ll need to reapply. It’s important to use fresh garlic, older garlic will be far less effective.
