Hedgehogs under Pressure, the Role of Rodenticides on Their Decline

Erinaceus europaeus, commonly known as the Western European hedgehog, is a well-known and widespread mammal in Europe. These small spiny mammals are insectivores and play a significant role in controlling invertebrate populations. However, they face several threats, including habitat loss, road accidents, and encounters with certain chemicals, including rodenticides. Rodenticides are chemical agents used to kill rodents. These compounds are often designed to be attractive to rodents but can also be consumed by other animals, including hedgehogs, either directly or through the ingestion of poisoned prey. Unfortunately, secondary poisoning through the consumption of poisoned rodents is a significant risk for hedgehogs and other non-target species. The ingestion of rodenticides can lead to severe health issues and even death. This brief review aims to present the impact that rodenticides have on European hedgehogs (European Erinaceus, Linnaeus 1758).
