Diatomaceous Earth (DE) is a totally natural, chemical free product to use against chicken lice and red mite.
It is made from the fossilised remains of diatoms and is a very fine white-grey powder. The silica shards cut through the waxy exoskeleton surface, effectively drying out the lice and red mites resulting in death.
Puff around the chicken house weekly during warm weather paying particular attention to perches and nestboxes. Add to the chickens dustbath and use on the birds themselves to eradicate body lice.
