Old carpets, the sleeping places of cats or dogs or any dirty un- fiwept corner may hold the eggs of the flea. The young breed in cracks and crevices, feeding upon organic matter there. Eventually they come to live as adults on their warm-blooded hosts, cats, dogs, or man. Evidently destruction of the breeding places, careful washing of all in- fected areas, the use of benzine or gasoline Flea which transmits Bu- in crevices where the larvae may be hid are j^ plague fr0m *** the most effective ...methods of extermina- tion. Pets which might harbor fleas should be washed frequently with a weak (two to three per cent) solution of creolin. Bedbugs are difficult to prove as an agent in the transmission of disease but their disgusting habits are sufficient reason for their extermination. It has been proven by experiment that they may spread typhoid and relapsing fevers. They prefer human blood to other food and have come to live in bedrooms and beds because this food can be obtained there. They are extremely difficult to exterminate because their flat body allows them to hide in cracks out of sight.
