There are stages to the life cycle of ticks that can be exploited as the weakest link in reducing an areas population.
There has to be soft-skinned mammal hosts for the progression of nymph stages to successfully result in the adult tick that feeds off big mammals.
It's during those multiple feedings, three or five or more, while maturing that they can pick up infectious diseases.
So - birds, mice, ground squirrels, rabbits... providing nesting material imbued with a pyrethrin-based insecticides (cloth/cotton balls in paper towel tubes is a start) or adding diatomaceous earth to an areas' dust-bath spots, spraying nest sites and/or having a way to get game to pick up dusting or drench effect at bait stations...
Sure it is not a perfect cure but in a couple of summers it can drastically reduce the adult tick population.
