歐盟於2018年禁止在戶外普遍使用類尼古丁類殺蟲劑。一項研究表明，法國以昆蟲為食的鳥類，如烏鶇和蒼頭燕雀的數量增加了2-3%。這顯示禁令確實起到了作用。然而，類尼古丁類殺蟲劑在美國仍然被廣泛使用。

The use of neonicotinoids for outdoor general purposes was banned by the European Union in 2018. Research shows that populations of insectivorous birds in France, such as blackbirds and chaffinches, have increased by 2–3%. This suggests that the ban has made a positive difference. However, neonicotinoids are still widely used in the United States.
