The hedgehog eats the slug that ate the pellet. Poison climbs the food chain one meal at a time.
What to avoid, and how it hides on a label
The slug eats the pellet, the hedgehog eats the slug. Banned for outdoor use in the UK in 2022 for exactly that reason: birds, toads and hedgehogs were dying second-hand.
A systemic insecticide is in the whole plant, pollen included. The EU banned outdoor use of the main three in 2018 for the bees; the same molecules are still sold for gardens in much of the world, imidacloprid most of all.
What to prefer
A hedgehog and a thrush are slug control. They need somewhere to sleep and something to eat, which is the untidy corner.
Slugs stop feeding; the predators that eat the slugs are not poisoned in turn. Less effective, and that is the trade.
Ten minutes, no chemistry, and you meet the night shift of your own garden.
The pick, honestly
This is the one card where the best product is no product. If you buy anything, buy the ferric phosphate kind and read the active ingredient, not the front.
No brand is named here yet. When one is, it will carry the date a person checked it, and it will never move the pick: there is no ranking to move.
If that is too much today
If you cannot go without, the bees are home by dusk and the flowers are where they feed. It is a smaller change that removes most of the harm.
The chain
pellet → slug → hedgehog → fewer helpers → more slugs
