Natular® SC is a liquid suspension concentrate larvicide used to control mosquito larvae in standing water, with the active ingredient being spinosad. Spinosad is a naturally derived insecticide from the soil organism Saccharopolyspora spinosa that acts as a unique feeding inhibitor, causing paralysis upon ingestion. Natular SC is applied using various ground or aerial equipment and is formulated to be highly effective against mosquito larvae while having low toxicity to mammals, birds, fish, and beneficial insects. It is toxic to non-target aquatic invertebrates, so care must be taken to avoid contaminating water sources.
Spinosad is highly toxic to aquatic insects, including dragonfly nymphs, and can cause significant mortality in these non-target organisms at concentrations used for mosquito control. Studies show that spinosad applications have resulted in substantial losses of dragonfly populations, as well as other aquatic insects like mayflies and diving beetles. Therefore, while spinosad is an effective insecticide for specific pests like midge larvae, its use in environments where dragonflies and other sensitive aquatic insects are present should be approached with caution due to its severe impact on these beneficial species.
