Organic, Pet Friendly Super Slug Killer

Use Doff organic Super Slug Killer to get rid of slugs! Completely safe around children, all animals, birds and wildlife - except for slugs and snails. This product has been embraced by commercial growers, gardeners, environmental groups and government agencies. The pellets control slugs and snails around all edible and non-edible plants.

When to use: At the first sign of plant damage use as directed during late evenings or early morning when slugs are most active.
Where to use: For use on bare soil, around all edible and non-edible plants.
How to use: Use 5g per square metre. Scatter evenly onto moist, bare soil. Repeat treatment may be necessary to maintain control to a maximum of 6 treatments at 5g per square metre, per crop.
How does it work? The pellets swell, absorbing water from moist soil, becoming more attractive to slugs. After consuming the pellets, slugs cease to feed, moving away once and leaving no unsightly traces.

Sluggo® Slug and Snail Killer

  • Certified for Organic use
  • Rain resistant
  • No more messy mucus trails everywhere

Sluggo organic slug and snail killer is a fast, effective way to control these garden pests and make sure you get to eat your produce rather than them!

Enviromentally safe, this easy to use product is ideal for use around both flowers and also fruit and vegetables too. It uses Iron Phosphate as its active ingredient, which is naturally occuring and will actually break down and add nutrients to the soil if it's unused. Water resistant too, the pellets swell up in wet weather, rather than dissolve, and thus become more attractive to slugs and snails. Once eaten, the pests will either burrow underground and die or simply crawl away and stop eating - no more messy slime trails and finding dead slugs and empty snail shells everywhere.

Use plant protection products safely. Always read the label and product information before use.
