Clean up all plant debris. Slugs hide in such places as under stones, planks, flowerpots, and damp places, therefore minimize these areas.
Cultivate soil as soon as possible in the spring to destroy dormant slugs (in the form of eggs).
Watering in the morning is strongly recommended to watering in the evening.
Slugs avoid borders of sand, lime, ashes and mulch of wood shavings (preferably oak).
Set out saucers (or sink coke cans or beer cans minus the pull tag) of beer or fermented grape juice, which will attract them. Salt can be added to this to dehydrate them, and flour can also be added to make them stick in the liquid. Immerse saucers or cans in the soil so the top of the can or saucer is at surface.
Instead of beer, try 1 tbsp. sugar in 2 litres lukewarm water and 1 tsp. yeast.
Collect slugs by putting lettuce or cabbage leaves on the garden and collect them early the next morning.
Fly screen or sheet metal about 10 cm wide will provide an effective barrier against slugs. It should be set in the soil on its edge to a depth of 5 cm, and surround the plant.
- Diatomaceous earth.
- Metaldehyde dust, can be put under boards and leaves.
- Metaldehyde dust (Green Cross) “Slug Destroyer Pellets”. Do not let it touch the plants.
- Application is best in warm, moist conditions. Rain following the baits, decreases the effectiveness.
Poison bait, 20 lbs/acre of:
- 1 pound Bran
- ½ ounce Metaldehyde
- 2 tbsp. blackstrap molasses
- 1 pint water
These poisons should not be used in the presence of dogs, cats and birds, as they too are attracted to them and will also be poisoned.
