Pesticide use in gardens causes harm to a wide range of wildlife including hedgehogs, birds, amphibians, and invertebrates through direct toxicity and food chain effects.
Garden pesticide use causes harm to wildlife at multiple levels: direct toxicity to target and non-target species, secondary poisoning through food chains, and destruction of habitat and food resources. Wildlife-friendly pest management using physical barriers, biological controls, and tolerating some pest damage achieves most garden goals without these welfare costs. Pesticide-free gardening is achievable for the majority of garden management tasks.
