Neem oil is a great natural way to get rid of them.

Put about a tablespoon or so of Neem oil into a spray bottle with slightly warm water (maybe 8-10oz) and a couple drops of dish soap. Shake it up and soak them.

Only thing I'd caution against with this is spraying your produce or herbs, because the Neem does have a scent that could throw off the flavor of things. Looks like a lily of sorts here so you'd be fine
