The answer to 'why do I have tick' is that ticks are common pests that can infest homes and yards, especially in areas with lots of vegetation or wildlife. Ticks feed on the blood of humans and animals, and they can transmit diseases like Lyme disease, Rocky Mountain spotted fever, and ehrlichiosis.
Some common causes of tick infestations include having tall grass, shrubs, or leaf litter in your yard, as these provide ideal habitats for ticks. Pets that spend time outdoors can also bring ticks inside the home. Symptoms of a tick infestation include finding ticks on your body or pets, experiencing tick bites, and noticing an increase in tick-borne illnesses in your area.
