Mosquito Bite Prevention Treatment:
An ounce of prevention is worth a pound of cure... I had dreadful reactions for 20+ yrs. Swelling and incomprehensible itching. The kind that can drive you half mad and make you want to claw a hole in your body. And I thought I'd tried everything over the decades; every potion, lotion, even hot spoons. Nothing worked. If there was one of these devil tormentors within a 10 mile radius it seemed to find me. I finally found relief in Vitamin B1 (Thiamine) in 400-500mg taken daily, no less. The remedy came from a pharmacy in Thailand. Allegedly mozzys don't like the smell, though we can't smell it. It shocked me it worked so well. I got the odd bite but it didn't swell, remained tiny, and barely an itch. Before I'd have 12+ welts with tormenting itching. Now I only get 1or 2, no welts, and no bother.
Friends who travel in hot mozzy infested areas were impressed too. They'd start taking it a week before their trip. But taking the right dose seems vital. If the dosage was skimped (300mg or less) it didn't work. Some take it in divided doses am/pm but I just took it all at once, so can't comment if that's more effective. I've also read Vitamin B1 is not a systemic mosquito repellent, but I am can attest it works great for me. Cheers.
If you have pots and pans or small ponds of rainwater in your yard squirt a very small amount of any hand dishwashing liquid on them. This breaks the surface's attention of the water and mosquitos cannot land on the water to lay eggs. This trick really works and reduces mosquitos if you collect rainwater or have small ponds of water in your yard.
VITAMIN B FOR MOSQUITOES
I used to attract Mosquitoes. I had Banana Trees in Kona with big leaves that held rainwater at the leaf stem. When I went near the trees in the rainy season, they would swarm all around me. I used skin so soft to repel them. That works if you put it on your skin every day. I was told about vitamin B and started taking a full complex of vitamin B, two tablets every day. That stopped the Mosquito bites. Some would swarm near, and occasionally one would land. But no bites. After a while, I reduced to one tablet every day. I went about ten years without one bite taking complete vitamin B every day. The only exception was when I was moving recently, I received a mosquito bite before I moved, and after I moved, I received a second bite. Vitamin B is a stress vitamin, and the move was more stressful for me.
Our granddaughter came to Hawaii once a year during the summer, and immediately she was attacked around the Banana plants. We gave her two vitamin B a day for three days. After that, we reduced it to one pill per day. She wasn't bothered again until she went home to Tennessee. After a few bites at home, she started taking vitamin B, successfully deterring Mosquitos.
I know a few tests that have been made discounting the effect. It has worked for me. Good luck.
