In Broward, mosquito control workers will be spraying larvicide in neighborhoods in central Broward over the next two weeks. The spray is harmless to humans and pets.

Mosquito larvae thrive in containers around people’s homes and grow in standing water and even containers as small as a bottle cap.

Recent rains helped to create good conditions for the mosquito larvae to grow.

The big fear from the adult mosquito is diseases like Zika, yellow fever, and dengue.
