In the Northeastern United States, deer ticks are carriers of the Lyme disease bacteria and can pass the disease onto adults or children by biting. The good news, though, is that it takes a day or two after a tick attaches to the skin before Lyme disease will spread. Therefore, it is super important to do regular skin check on anybody in your household during the aforementioned months, especially if you spend a lot of time outdoors or have animals that go outside.
