Which ticks are found living indoors more often than other ticks?

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

Answer: (C)

The key idea is how tick habitat and host preferences shape where they’re most commonly found. The brown dog tick is notably adapted to indoor life and can complete all life stages inside homes or kennels, often staying in the same area where dogs rest. This indoor tolerance means they’re found living indoors more often than other ticks, which are mainly outdoor feeders that inhabit grasses, brush, or wooded edges and only occasionally end up inside.

The other ticks shown are typically outdoor ticks, associated with outdoor environments and wildlife. They may bite indoors if they’re brought inside on a pet or person, but they don’t establish indoor populations as readily as the brown dog tick.
