I could walk out my back door in Western Maine, snap off a few emerging asparagus spears, and be a Lyme disease patient. The ticks that transmit that disease at this time of year are smaller than the period at the end of this sentence. As I don't particularly want to be picking asparagus with my hands covered in pesticide, I'll take the chance.

Mosquitos who transmit Zika are daytime mosquitos, they are far easier to see than tick nymphs and far easier to repel or discourage.

Certainly I'm way past the age of being concerned about childbearing, but I was never much concerned about Dengue Fever in the islands, either. Transmitted by the same mosquito species, but daytime sailing keeps one out of the reach of those critters.

Caution is one thing, fear is another. Everyone gets to decide what risks to take.
