It sounds like you’re referring to “tick riders”. These are USDA/APHIS employed agents that are specifically looking for cattle fever ticks which is another vector we had pushed back into Mexico that has made a comeback in recent years. There is a permanent quarantine zone along the border that is monitored for cattle fever ticks.
