Yes, I use bleach and it's literally been a life saver for me. I'm deathly allergic to ants. I go into anaphylactic shock which can cause death by suffocation within minutes. If I'm at home when I get a bite, I apply a cotton ball soaked in bleach and it prevents an allergic reaction. It's a whole lot easier than rushing to the ER or injecting epinephrine and Benadryl and then sleeping it off for the next 12-18 hours.
Disclaimer: This may not work for everyone. If you're allergic to ants, be sure to keep epinephrine & Benadryl around just in case.
