Neonicotinoids are a type of pesticide used on a wide variety of crops in this and other countries. They can be long-lasting, effective against many insects, can be applied via seed coatings, and are less toxic to mammals than other pesticides. Those first three attributes are why they have raised many concerns among conservationists and environmentalists. Lots of insects are beneficial to us and even those that are bothersome can be important food for other creatures, especially birds. Birds eat seeds as well as bugs.
