Pellets are a complete con, don't waste your money!

They take a long time to poison the slugs and in the meantime while the slugs are dying they are an easy target for all the natural predators like birds, hedgehogs and beetles.

A single hedgehog can eat its own bodyweight in slugs every night. So for every hedgehog you kill by using pellets you can literally get thousands more slugs.

The only time slugs get out of hand is when the natural balance is upset - often for example when someone is using pellets. Use an organic alterntive like nematodes and you'll save time and money.
