Which tick species is most commonly indoors?

• A. Brown dog ticks
• B. American dog ticks
• C. Gulf Coast ticks
• D. Lone star ticks

Answer: (A)

Some ticks are especially adapted to living inside buildings because their host spends a lot of time indoors. The brown dog tick fits this pattern well, as it is highly associated with dogs and can complete its entire life cycle inside homes, kennels, or shelters when conditions are warm and dry enough. This indoor preference means you’re more likely to find a stable indoor population of this tick than of others that rely more on outdoor environments like yards or woodlands. The other species tend to be more outdoorsy, turning up indoors mainly when they hitch a ride on a host, rather than establishing a lasting indoor presence.
