I live in Tampa Bay Florida. I am very prone to mosquito bites. Not a single one and this is my second year using para'kito.
I bought it for my 16 month old because he hated being sprayed and I didn't want him to breathe in all those toxins anyways. I'm pretty happy with this product.
I ordered this for my daughter as she is always being bitten by mosquitoes. When my daughter wore it at camp, where bugs are the worst, she had it on her left wrist. She ended up with 1 mosquito bite, on her right calf. I would say that you may want to consider two for better protection.
