Most pure Neem once mixed has a shelf-life of around 4 days. We add a plant-based oils to the blend that extends the shelf-life of the Neem to 18 months, as well as acting as a wetting agent so the nozzle won’t clog up. These oils also extend the potency of the Neem on the plant after spraying. We do not use any synthetic preservatives in the mix.
Is it safe to use around children and pets?
