The answer to 'how did tick get in my house' is that ticks can easily be brought into your home on pets, clothing, or other objects. Ticks are small, blood-sucking parasites that live outdoors in wooded, grassy, or brushy areas. They wait on the tips of tall grass or bushes and latch onto people, pets, or wildlife that brushes by.
Once inside your home, ticks can hide in cracks, crevices, bedding, and furniture, and continue feeding on their hosts. This can lead to tick infestations and increase the risk of tick-borne diseases like Lyme disease, Rocky Mountain spotted fever, and others. To prevent ticks from entering your home, it's important to check pets and inspect clothing and gear after being outdoors, and to maintain a tick-resistant landscape around your home.
