: I know deer transport the ticks over a wider range, but the main
: carriers of the disease spirochete are field mice. So how does
: preventing ticks from hitching a ride on deer keep the little
: critters from thriving on mice where they're already
: established?

Maybe it just helps to prevent spread to previously non-infested field mice?
