Mouth part is much longer than brown dog tick mouthparts.
Brown dog ticks seldom attach to humans. Permethrin clothing treatment kills ticks and deet-based skin repellent helps repel them. Note the circular dark spot above the mouthpart . . . The shield does not change as the tick engorges and it is the key component, along with mouthparts in identifying different ticks. Because the engorged deer tick is often confused with the brown dog tick, we have included the same photo series so you can compare the two species.
