I avoid grass all together- especially in the woods.
If I'm going off trail I cram my jeans into my boots and shake everything out before getting in the car. Ontario ticks are just a part of the experience now :/
My body helps me with this goal by being ridiculously allergic to all grasses.
Or avoid the trails all-together. Given the 30th anniversary of Trainspotting this seems relevant: https://youtu.be/xtbS_PdA198?si=8ba8Fp8_uzdpIq6J.
I’m pretty wary of ticks, when you go for hikes just do a body check after. Also, I tend to go with long pants (even in summer, I dislike bugs more than the sweat).
Plus a lightweight windbreaker can help to cover upper body. Plus it limits sun exposure which is also harmful.
