Neonicotinoids are especially dangerous to bees and other insects because they are absorbed into plant tissues and distributed to new growth, including pollen collected and eaten by bees. This class of insecticide is known for its persistence in plant tissues and the environment, remaining deadly for months or even years. An increasing amount of evidence links neonicotinoids to the decline of bee populations worldwide.
The best advice: Purchase plants from local growers who don’t use synthetic chemicals—or start your own plants from untreated seeds. Learn more about the Friends of the Earth BeeAction campaign at foe.org/beeaction.
