Fungicides - fungi.
Larvicides - larvae.

How long do pesticides stay in the body?

"Older pesticides like DDT can stay in the human body for years, even decades," Landrigan said. But Dr. Josh Bloom of the American Council of Science and Health says these chemicals have been used in the U.S. for at least 60 years and pose no risk.

What happens if you breathe in pesticides?
