I'm not advocating venturing into Zika land, merely giving over my experience.
I can't recall a single destination I have gone to that my wife and child didn't get bitten up the first day. My son could probably get a mosquito bite in a sterile vacuum chamber.
I just came back from hot and humid Indonesia where I frolicked amongst the outdoor creatures, mosquitoes being one of them. I hung out by the pool at dusk, took walks among rice paddies, and sat outside by a performance whose TA reviews all say to bring mosquito repellent for. And having just landed back in Israel I can say that none of us have gotten a single bite from those blood sucking parasites. I have never had any repellent or method that worked this well so I figured I would share what I used .
I purchased
this for my clothing which I sprayed the night before and
this for my skin which I applied in the morning before heading out.
