And some people react more strongly to mosquito bites than others. Frankly, though, I think these work only if the mosquitoes are not too populous, and if you apply the stuff frequently. For some reason, black and white fabrics particularly seem to attract the bugs. Once you're bitten, you can try a couple of things. I use a bit of Red Tiger Balm dabbed on the bite to distract myself from the itching.
Some people use aloe vera.
If you can reduce your allergic responsiveness through changes in your diet or mental attitude, mosquito bites may not bother you so much. It's something you can experiment with. Try eating garlic or reducing the protein in your diet. High levels of protein can irritate the immune system, aggravating your reactivity by making it more difficult for cells to recognize foreign materials in the body. You also may want to try taking vitamin B-1 regularly during the summer months.
