Which pesticides are listed as toxic to wildlife?

• A. Mexacarbate and Carbaryl
• B. Sevin and Aldicarb
• C. Carbofuran and Aldicarb
• D. Mexacarbate and Sevin

Answer: (C)

Pesticide labels include wildlife toxicity warnings, telling applicators when a product can pose immediate or serious harm to birds, mammals, and other non-target wildlife. Carbofuran and aldicarb are well known for their high toxicity to wildlife, with low LD50 values for many species and rapid adverse effects if wildlife are exposed through direct contact or through contaminated food or water. Because of this, their labels clearly indicate toxicity to wildlife and place strict usage restrictions to minimize harm to non-target organisms. Other common insecticides like carbaryl (Sevin) and Mexacarbate may be toxic as well, but they do not carry the same explicit wildlife-toxicity designation on their labels in the context of this question, so they’re not the ones singled out as toxic to wildlife.
