When I was little, and regularly played on hillfarms, in among bracken, long grass, etc., camped along lochsides, etc., we never had ticks. Not once.
The first tick I ever got was up Loch Aweside when we camped beside the river to do white water kayaking in my late teens. Never saw another one until nearly twenty years later.
You know what changed ? they stopped the use organophosphates to dip sheep, and the deer numbers kind of exploded.
Suddenly every where folks go now they have to be aware of ticks, even in suburbia.
I dread finding them in my garden, but if I do, I'm going to find someway to kill them off. Even if I have to buy quail and keep them for a couple of seasons. It'd be worth it to be tick free.
