Gardeners Warned Against Using Slug Pellets to Protect Hedgehogs
Gardeners have been urged to avoid using one common product in their gardens to protect hedgehogs, which are now vulnerable to extinction in the UK, according to the RSPCA. With summer heatwaves following weeks of unpredictable weather, many people are keen to enjoy their outdoor spaces, but certain gardening practices pose serious risks to these animals.
The RSPCA describes hedgehogs as “an important part of the ecosystem” and “a gardener’s friend” because they eat beetles, caterpillars, worms, and other invertebrates that can harm plants. However, hedgehogs seeking sanctuary in gardens can face danger from tools and products meant to control pests.
Slug Pellets: A Hidden Danger to Hedgehogs
Guidance issued by the Royal Horticultural Society (RHS) urges people to avoid using slug pellets, which are small, poisonous baits scattered around gardens to protect plants from slugs and snails. When pests consume these pellets, they stop feeding and eventually die, but the toxins can also harm hedgehogs.
The RHS states: “Dig around in the back of the garage or shed to make sure you don’t have any old metaldehyde-based slug pellets lurking there. These are now banned due to their high toxicity to wildlife, so must be disposed of safely at your nearest recycling centre.”
Metaldehyde slug pellet sales are banned in the UK. Most traditional brands have been replaced with ferric phosphate, which is certified for organic growing and is safer for wildlife and pets. Gardeners are advised to check for any old metaldehyde pellets and dispose of them properly.
Legal Protections and Conservation Status
Under the Wildlife and Countryside Act 1981, it is illegal to kill or capture wild hedgehogs using traps, nets, or poisons. The Natural Environment and Rural Communities (NERC) Act 2006 lists hedgehogs as a “species of principal importance in England and Wales,” requiring public bodies to take steps to conserve them.
The RHS also warns that hedgehogs are nocturnal and should generally only be seen at night. If a hedgehog is spotted during the day, even if it appears healthy, it may be in trouble. The society advises calling the British Hedgehog Preservation Society at 01584 890 801 for guidance.
Safer Alternatives for Gardeners
The RHS notes that “slugs and snails have many benefits in the garden, so it’s best to tolerate a level of damage by the minority species that do feed on live plants.” Though not a mainstream food source, hedgehogs may consume slugs or snails, and any toxicity from slug pellets present in those prey would be passed on.
Gardeners are encouraged to use wildlife-friendly methods, such as encouraging natural predators, using barriers, or opting for ferric phosphate pellets. By avoiding harmful products, gardeners can help protect hedgehogs and support their conservation.
