Larvicides work by disrupting the development of insect larvae, preventing them from maturing into adults capable of spreading diseases. They can be applied directly to water bodies where larvae breed, such as ponds, marshes, and other stagnant water sources. There are several types of larvicides, including biological larvicides like Bacillus thuringiensis israelensis (Bti) and chemical larvicides such as organophosphates and insect growth regulators.
