I came across this page that talks about using tobacco for poultry http://sustainableseedco.com/Poultry-Package.html "Historically many homesteaders would soak tobacco leaves in water and even boil the mixture down. They would take this and spray/paint it in the coops to kill mites, lice and all manner of bugs. Care must be taken not to get it on your skin, so wearing gloves is always a good idea. Homesteaders would also dry the leaves, then grind them into a powder and dust poultry during mite season. They also put it in the next boxes for the same reason. Again, wearing a face mask when dusting your chickens is a must. Obviously you do not want to get it in the chickens eyes or mouth no matter what you use." I was wondering, does anyone else do this and do you think it is effective?
