Defender™ Snail & Slug Pellets

There's nothing quite so disappointing as checking on your latest vegetable, herb and flower seedlings to find half of them have gone! Vanished overnight, no trace, simply GONE. The usual suspects are snails and slugs, whose voracious appetites may see them consume dozens of young plants in a matter of hours. Tried and true Defender pellets will soon have them under control.

  • Fast and effective control of snails and slugs
  • Bran based to attract pests away from your seedlings
  • Scatter lightly and often for best results
  • Resealable packaging
  • Use a bait trap to protect pets

Scatter rather than heap

Pellets work best when scattered lightly around young plants to protect them, rather than in heaps, which could be attractive to domestic and native animals

Bran based

The pack can be resealed after opening to prevent moisture getting into the sachet and affecting the pellets, It is also showerproof - storing packs outside where pets and children could reach them, however, is not recommended


600g and 1kg packets, with or without child-resistant cap

Suitable for

Eradicating snails and slugs around all plants including vegetables, herbs and ornamentals

Not suitable for

Do not leave pellets exposed on the soil when domestic pets are present - use a bait trap (available from most hardware stores)

Do not use if it is raining or rain is expected - the bran-based pellets will absorb moisture and break down before snails and slugs have had a chance to find them

How it works

The active ingredient metaldehyde is poisonous to snails, slugs and other gastropods
It works on contact or by ingestion (pest eating it)
It is soluble but it is not absorbed by plants and does not enter the food chain

How to use

  • Sprinkle pellets lightly around plants to be protected
  • Don't place them too close to plants - the idea is to attract snails and slugs to the baits and away from your seedlings
  • Apply every few days - the pellets degrade when exposed to weather and the active ingredient is soluble, washing into the soil when you water or it rains

For a complete guide on how to use Defender Snail & Slug Pellets, always check the packaging

When to use

Whenever snails and slugs are present, especially after planting out young seedlings. Sprinkle around the garden after rain, when snails and slugs emerge to eat.

Safety Information


  1. The pellets are dangerous if pets consume enough of them
  2. If a pet has eaten snail pellets, seek urgent veterinary attention
  3. Symptom onset is rapid and small dogs may deteriorate rapidly if veterinary assistance is not sought quickly
  4. MAKE SURE you take the pack with the pet to the vet
  5. Poisoning most often occurs when a hungry pet, mistaking the pellets for pet food, knocks down a packet and wolfs down the contents

Pets and wildlife are not at risk from consuming snails that have already been killed by the snail pellets, because the product will have been metabolised and rendered harmless in the snail or slug gut.
