Chlorophyll will keep mosquitos and other bugs away. I have found that by taking a small amount of liquid chlorophyll ( 1/2 tsp ) or a capsule or two that mosquitos are no longer a problem. That applies to most mosquitos. About 3 yrs. ago we had a rare strain in Texas that it would not keep off. By taking the chlorophyll we have no problem when fishing or sitting outside in the evening. It even worked in Minnesota on a fishing trip. It also helps with body odor and that is a plus in the hot summers around here. It takes 2 or 3 days to get built up enough in the system, so use your bug spray until then.
