It's insidious, if you spend time in nature you are exposing yourself to it. The ticks will be on tall grass, falling from trees, crawling from the ground. How can that be avoided?
During summer we have to check ourselves for ticks every single night, my girlfriend lives in a house inside a wooded area, I have a big garden on my house where deers are commonly spotted (this past month I've been visited by one every single day).
No, it's not easy to be avoided if you leave the house, just laying on my lawn or garden grass is enough to get me paranoid about it. My housemates have already found 3 ticks stuck to them.
Please, if you know an easy way to avoid all of this I'd love to hear it but so far I only know to be cautious and vigilant.
I'm late to this so don't know if you'll see it, but I live in rural New England and ticks have become ever more horrendous here, yet I haven't had a single one in, a decade at least? The big thing for me has been getting a solid set of permethrin utilizing full coverage clothing (look for branding like "Insect Shield"), including socks and a hat with neck protection, combined with occasional judicious usage of repellent (I suggest 20% picaridin instead of DEET, something like Sawyer Products which has almost no smell and won't melt polymers that deet will). Having clothing that one can just put on for going out and boom high protection makes it so convenient vs applying repellent that I never fail to, and it has done exactly what was promised. They don't last forever, after 50-70 washings they need to be replaced, but if using them in a focused way for outdoor usage that can last a good while.
I'd still absolutely leap at a vaccine if available, but physical/chemical protection does work so the trick is making it convenient enough and enough of a habit to be 100% consistent about it.
How? Just working in my garden for an hour or two and I have a a good 1 in 4 chance of getting a tick bite.
