Q. After reading about hydrogen peroxide and Listerine, I wanted to add my method for treating mosquito bites. This was used on me when I was a child. With a cotton ball, dab Cepacol mouthwash on the bites. This stops the itching immediately.

A. We have heard from other readers that applying amber Listerine or hydrogen peroxide immediately can stop the itch of a mosquito bite. Cepacol mouthwash contains some of the same inactive ingredients as Listerine, in particular the alcohol base, eucalyptus oil and methyl salicylate (oil of wintergreen). Perhaps one of these is responsible for the itch relief.

We have also received testimonials praising vanilla extract, plaintain (Plantago major), hot water and even soy sauce to relieve the itch of mosquito bites. More people seem to use Listerine as a repellent, as this reader suggests:

“A spray of amber LIsterine mixed half & half with water makes a pleasant mosquito repellant both on the skin and at picnic sites or wherever the critters congregate.”

    I have always been a walking mosquito buffet. A couple of years ago I ran out of itch cream in the first aid box, much to my distress. Only item in there that came close was a tube of neosporin, the one that is + pain relief. Thought I’d try it since I had nothing to lose.

    Within minutes the itch was gone and stayed gone. My previous experiences with any itch reliever entailed having to reapply every hour or so for several days as the bites would continue to flair up again and again. Now one application of neosporin, and they are gone for good. Now I don’t leave home without my mosquito repellent or my neosporin since Florida is apparently a mosquito sanctuary.

    I soak a cotton ball in regular white vinegar — it really alleviates the itchiness quickly.

    My mom has told me that she uses oregano oil. She mixes quarter teaspoon of oregano oil to three quarters of olive oil together in a bottle and she takes a cotton ball and wipes her legs, arms, and face down. The mosquitos don’t bother her at all. She also uses the mixture and rubs her inside of her nostrils every day and hasn’t been sick in forever.
