“Foul brood” is a contagious disease to which bees are subject. It is caused by bacteria and its presence may be known by the bees becoming languid. Dark, stringy, and elastic masses are found in the bottom of the cells, while the caps are sunken or irregularly punctured. Frequently the disease is said to be accompanied by a peculiar offensive odor. Prompt removal of diseased colonies, their transfer to clean and thoroughly disinfected hives, and feeding on antiseptically treated honey or syrup are the means taken for the prevention and cure of the disease. The antiseptics used are salicylic acid, carbolic acid, or formic acid. Spraying the brood with any one of these remedies in a solution and feeding with a honey or syrup medicated with them will usually be all that is required by way of treatment. It is also said that access to salt water is important for the health of bees.
