What products are available for larval control of mosquitoes?

• A. Insect Growth Regulator, Biorational Pesticides, and Various Chemicals
• B. Only Biological Control Agents
• C. Only Mechanical Traps
• D. No Products Available

Answer: (A)

Larval mosquito control relies on products that target larvae directly in the water, using different modes of action. Insect Growth Regulators disrupt the development of mosquito larvae, preventing them from maturing into adults and thereby reducing the next generation. Biorational pesticides, such as those based on Bacillus thuringiensis israelensis (Bti) or other natural/biological agents, kill larvae while often posing fewer risks to non-target organisms. Various Chemicals covers traditional chemical larvicides that actively kill larvae, including approved organophosphates and other larvicidal chemistries. Together, these categories reflect the full range of larval-control products available, making them the best answer. Mechanical traps target adults rather than larvae, and saying no products exist is incorrect because multiple larval-control products are widely used.
