When I was younger mosquito bites didn't seem to bother me so much. There was hardly an itch and not much swelling either. Now they itch strongly and swell up more. I wonder if the mosquito saliva has become more "poisonous" in the last years? Luckily I don't get bitten much.
This boils down to having an 'adaptive' immune system. A mosquito will inject a cocktail of 20 or so proteins, including something to block platelets, something to block your immune system and something to stop your blood from clotting. The immune system is very good at reacting to foreign proteins, and the more you are exposed, the better your immune system can react. This means your immune system gets 'tuned up' to react, and so you can get a stronger reaction more quickly. But not everyone's immune system will adapt in the same way.
Monika asked the Naked Scientists: When I was younger mosquito bites didn't seem to bother me so much. There was hardly an itch and not much swelling either. Now they itch strongly and swell up more.

I am no expert but have known someone with your reactions only in reverse and they found she was deficient in certain vitamins and when they corrected the deficiency her reaction became less severe and very tolerable.. but when she was down again then her bites were worse.. once regular monitoring began they were able to have her increase her uptake of certain foods to bring up her levels and prevent such serious effects.
Eating better is always a good thing, I'm eating a lot of veggies, YUM. Perhaps I should have my vitamin levels checked, worth a try.
Monika as far as I know that i's mainly the female mosquitoes
Here too sometimes both winter and summer.. not every winter but many when the cold is more mild.
Or citronella into your clothes or in your food then it's in your
Thank you Naked Scientist for the answer om the show!
Dear all, first let me start with saying that I am doing a report on mosquitoes with my friend (we are in our last year of high school) and we did an experiment, where we tested if consuming garlic, alcohol and vitamin B would have any effect on mosquitoes. now I am wondering if you could give me a more detailed answer as to what exactly attracts the mosquito (to us, human beings)? and do you perhaps know what components are in the saliva of a mosquito? (if this is too general; I would be mostly interested in the Anopheles kind - Anopheles Atroparvus - to be exact) I am looking forward to hearing from you soon! Greetings M.
