Homemade slug repellent

Updated February 21, 2017

Slugs in garden and lawn areas can do a lot of damage to your flowers and plants if left to slither free. Many commercial slug repellents use toxic chemicals to kill or keep slugs away, but some milder options also are effective. By making your own homemade slug repellent, you will save time and money and know exactly what additives are getting into your garden soil.

Slug juice

Make a batch of slug juice to spray around the perimeter of your lawn or garden to keep slugs, flies and even cats and dogs out of your garden. Put on some rubber gloves, capture four or five live slugs and drop them into a manual grinder. Pour 250 ml (1 cup) of water on top of the slugs and begin twisting the handle. Grind the slugs into a mush and pour the remains into a bowl, straining out the solids with a piece of cheesecloth. Pour the remaining liquid through a funnel into a spray bottle and spray the slug juice around the perimeter of your garden or lawn. Keep your gloves on at all times because the juice has a foul smell that you will not want on your hands. It is this foul smell that will keep pests away from the areas you spray.

Water method

Slugs thrive in moist environments, and there is a good possibility you provide one for them. If you water your lawn and garden at night, the slugs will thank you for it. Slugs are most active at night and need moist soil to go about their destructive ways. Water your gardens early in the morning instead and allow the sun to dry the soil throughout the day. By night-time the soil will not be a desirable place for the slugs. This can cut down on the slug damage in your garden by up to 80 per cent.

Seaweed control

If you live in a coastal area, gather some seaweed for use as a slug repellent. Place the seaweed around your plants as a protective barrier. Pile the seaweed 10 cm (4 inches) deep and wait for it to dry. When the water evaporates, it'll hardly be noticeable. The seaweed shrinks as it dries up and becomes very salty. Slugs avoid salt at all costs because it kills them, so you won't have any problems with slugs crossing this barrier.
