The brood remains do not adhere to the cells; there- fore, the bees are able to remove them and the disease does little damage. TREATMENT BURNING DISEASED COLONIES It is now commonly recognized that the safest, and in the end the most economical, means of stamping out American foulbrood is to burn the diseased colonies. While this procedure may seem wasteful to those who believe that less drastic measures afford ample protection, it is the only method that leaves no op- portunity for the disease to recur, thus relieving the mind of the bee- keeper. Diseased colonies should be burned as soon as possible aft- er the infection is discovered. Before this is done, how- ever, the bees must be killed. A table- spoonful of calcium cyanide, an ex- tremely poisonous chemical which must be handled with great care, spread on a sheet of paper or cardboard and slipped into the entrance of the hive (fig. 6), which should be left open, will kill the bees in a few minutes. As as an extra precaution additional cyanide may be thrown into the top of the hive, since occasionally the bees fall onto the poison placed in the entrance so rapidly as to prevent the fumes from penetrating all parts of the hive. AH field bees that try to gain entrance to the hive will also be killed. Gasoline is sometimes used to kill the bees. In such cases the entrance to the hive is closed, a pint or more of gasoline is then poured over the top frames, and the hive is closed tightly. After the bees have been killed, the contents of the hive should be burned with the least possible delay in order to avoid trouble.
