My son lives in Pennsylvania. I live in Florida. He is always calling me about the mosquitos near his home. He says that they are "so bad, that we can't even have a family dinner out on the deck.". I saw this item and told him about it. He looked at the reviews, thanked me for the suggestion, and said I should keep my money in my pocket. I said, "In my opinion, it's worth trying. You can always return it if it doesn't work, and you have 90 days to try it out." He was convinced to try it. A few days later he called to say that he received it. A few days after that, he called me asking me if I could buy him another one for the other side of the deck!
