Fighting mites and lice...
This is a problem I have had a lot of contact about, it is an ongoing problem for poultry keepers.
They come in the form of feather mites, mites, red mite, leg mites, lice, louse, but they can all be treated the same way
Mites - Small dots that live in wood, so hen houses cracks, corners, perches but feed on the hens over night. If there are no wooden parts they live on the hens, they also do this if there are too many mites in hen house already. These mites will leave your hens with feather loss, anaemia, poor egg production and in severe cases death
Red Mites - Small dots that live in wood, so hen houses cracks, corners, perches but feed on the hens over night. If there are no wooden parts they live on the hens, they also do this if there are too many mites in hen house already. These mites are aggressive feeders and will leave your hens with feather loss, anaemia, poor egg production and will eventually cause death.
Louse/lice - Larger than mites, and clearly obvious when you look under feathers. They live on hen all the time, cause irritation, featherloss, anaemia, and poor egg production
Louse eggs
Leg mites - These are almost invisible mites that live beneath the scales on hens legs. They cause severe itching and pain, and eventually push up the scales and deform their legs, this can result in loss of toes, feet, and cause severe infection and death.
Any hen is vulnerable to mites or lice, they thrive in wet and warm conditions. Often parasites are transported to your hen house by straw, hay and bedding, and other times pigeons, pheasants, wild rabbits and birds.
Like everything there are hundreds of brands and potions claiming they work to kill mites and lice. We have tried most of them ourselves.
The best powders and sprays are those that have insecticide in, everything else takes a long time to work over a number of weeks.
At LHR we use the below products.

The best cure is prevention, if you use the above products monthly mites and louse will never take hold.
If you do have a problem already treat and then treat again in a weeks time to cover any that may have escaped.
Good luck.
