My first theory being busted, let’s try this:
How long does it take mosquito bites to go away?
How often and for how long are you bitten?
Me:
30 minutes
Daily in the Summer for 20 years.
Why do people keep giving this answer in minutes or hours? I don’t get bitten that often but they cause visible marks and itching for a week or so when I do. That is the experience of most people as far as I know yet the freaks 
here keep answering completely differently.
I want to find out why I am different from all of you, and you laughh at me.
Mrs. Plant has a bad reaction to mosquito bites. They last for days. Mine just a few minutes. She is from New England, so I thought maybe “foreign” mosquitoes mess you up more than your “local” ones. It does not appear to be true.
So maybe we build up immunity if we are bitten a lot.
Thanks for participating.
Mosquitos don’t seem to bite me as much as other people, and when they do, they leave no mark, and it does not hurt or itch. I never worried aout mosquitos or used bug spray until I began hearing more and more about diseases.
As an example, last Sunday we were sitting outside with some friends. Someone said “There’s a mosquito on your arm.” I saw it and squished it - it was full of my blood. Absolutely zero redness, swelling, pain, or itching.
I spend a lot of time outside gardening, golfing, and walking my dogs. So I assume I get bitten several times a week.
How long does it take mosquito bites to go away?
Immediately/no effect on me. When I was younger I used to get the itching and bumps. That stopped around the beginning of high school.
How often and for how long are you bitten?
I grew up living in the woods, near a marsh, in rural Minnesota. I lived there until I went away to college. So, during mosquito season I was probably bitten about once every 4 minutes.
1.) Anywhere from a few days to a week. (Sometimes the bites can swell up to dime- or nickel-sized.)
2.) I got bitten a lot during the summer as a kid/teenager (early '80s through late '90s, let’s say). Now I get fewer bites because (a) I’m not outside all day during the summer, (b) I haven’t had a chance to go camping for a few years, and (c) when I am outside, I tend to remember bug spray if I’m going to be somewhere with mosquitoes.
1.) At least 3 days, but usually a week.
2.) Not very often. Once a month or so I’ll forget to bug spray myself before an evening outside, and then I’ll get at least ten bites, but I try to avoid that sort of thing. When I was a kid I was constantly getting bitten from June to September.
And my reaction? Bad.
When I was little, the first mosquito bite of the season would become a huge inflamed patch as big as a pancake. (The summer when the first mosquito hit my face was pretty bad. Fortunately, three-year-olds don’t really get embarrassed.) Nowdays, I get hard little lumps instead of flat patches, but I can’t say it’s much of an improvement.
about two weeks to totally clear, but a day or two of itching, relieved by using peroxide.
Daily in summer (and here, we can have summer-type weather for 4-5 months).
I have a theory that it may depend on the particular species. When we vacationed in the Florida Keys (first time for me), we were dining outside in the evening and I ended up with quarter-size red marks, more like welts; I don’t recall how bad the itching was. I don’t think I was even aware of the bite until later in the evening. When I asked a resident about it, he said you become immune after awhile. Don’t know if he knew what he was talking about, but I didn’t have that experience on future visits to the Keys. Here in northeast Florida, the skeeters are very small, but I can feel the bite. I was outside today for just 15 minutes, and my legs are itching like crazy now. I’ve been here for five years and I’m not “immune” yet, so I’m doubting the “immune” theory. Maybe individual chemistry? Hubby doesn’t have much of a problem with them. Maybe some of us just taste better than others.
