Dog Ticks Types and Information
There are eight different species of ticks that attack dogs, but most people know them all as “dog ticks”
or “wood ticks.” Practically all of them also bite human beings. Several carry Rocky Mountain spotted fever and tularemia, or rabbit fever. All have somewhat similar habits and life histories and must feed on blood to reproduce.
The American dog tick, the most widely distributed and abundant, is found particularly along the Atlantic and Gulf coasts, in the Mississippi Valley, and along the Pacific Coast south of Oregon. It carries Rocky Mountain spotted fever and tularemia, though these diseases do not occur everywhere and only one tick in several hundred is actually infected. An engorged female deposits 3,000 to6, 000 eggs in a mass on the ground, and the seed ticks and nymphs feed on meadow mice and other rodents. The adults feed on dogs, other large animals, and human beings. Larvae and nymphs can live a year without feeding and adults over 2 years.
The best way to control these and other ticks is to immerse or wash the dog regularly twice a week in a derris dip (1 ounce of mild soap and 2 ounces of derris or cube powder to each gallon of warm water). The liquid will keep for 2 or 3 weeks in a tank in a dark place, but if no dipping tank is available the dog can be washed thoroughly in a tub. In lieu of dip, derris, or cube powder may be applied as a dust. Ticks can also be removed individually with tweezers and dropped in turpentine or kerosene, care being taken to prevent infection. Destruction of rodents, keeping vegetation closely cut or grazed, burning over, and spraying vegetation with nicotine sulfate are all useful control measures under certain circumstances.
Other ticks described are the Rocky Mountain spotted fever tick(Rocky Mountain region), the Pacific coast tick (California and southern Oregon), the black-legged tick (Eastern and Southern States),the California black-legged tick (Pacific coast), the Gulf coast tick(Gulf and southern Atlantic coasts), and the lone star tick (Eastern States as far west as Texas). For each of these, certain of the control measures recommended for the American dog tick are applicable.
Two other ticks require different treatment. The spines ear tick, which gets deep into the dog’s ear, can be killed with a few drops of derris or cube powder mixed in medicinal mineral oil and dropped into the ear; or a mixture of pine tar and cottonseed oils may be used. The brown dog tick, which occurs all over the United States, can live entirely indoors in heated buildings, needs no other animal except the dog on which to complete its life cycle, and is especially difficult to eradicate. The derris dip should be used at 3-day intervals. Wooden kennels should be sprayed with undiluted creosote oil and metal kennels with triple-strength creosote dip (or a blowtorch may bemuse along cracks). In dwelling houses, pyrethrum-kerosene sprays and powder may be employed to combat infestations.
