Preventative sprays?

[Amydeluna00]

Saw this at the poultry aisle.. has anyone used this or any other preventative spray for mites and lice? It’s said to be natural from herbs, can be sprayed directly on the chickens if desired and has no egg withdraw
Not 100% convinced on using DE or the famous Saturday lime

Doesn't do a single thing, neither lime or especially d.e are necessary in most places.
