Guess I will throw my two cents into the mix. Earlier this summer some friends of mine went on a missionary trip to an area where the different mosquito viruses were active. Naturally they were worried about mosquito bites. Another friend who goes to Haiti on a regular basis said to take Vitamin B 1, two a day before you go on your adventure and then one a day for the rest of the time. I guess Vitamin B 1 emits an odor through your skin that mosquitoes do not like and avoid it.
Extra Thiamine May Make Mosquitoes Think You Stink
A study back in the 1960s indicated that taking vitamin B1 (thiamine) may be effective in discouraging mosquitoes from biting. However, studies since then have been inconclusive.
18 The theory is, taking more vitamin B1 than your body requires causes the excess to be excreted through your urine, skin, and sweat. Vitamin B1 produces a skin odor that female mosquitoes seem to find offensive.
This vitamin is water-soluble, and there is no danger of toxicity—even at high doses—so it is a safe measure to try.
Dr. Janet Starr Hull recommends taking one vitamin B1 tablet a day from April through October, and then adding 100 mg of B1 to a B100 Complex daily during the mosquito season to make you less attractive to mosquitoes. You may also want to forgo bananas during mosquito season, as something about how they are metabolized appears attract mosquitoes.
If you are bitten by any annoying insect use a paste of baking soda and water, to reduce pain and swelling.
Around the house if you have any standing water like a small pond or birdbath you can buy these doughnut shaped cakes that when put in the water kill mosquitoes but do not harm birds or fish or wildlife or pets. They are called "Mosquito Dunks. " I use them in my birdbath.
