Why Do Mosquito Bites Itch So Much?

How much do you love that the weather has warmed up? It puts me in such a great mood, since I am spending so much time outdoors. I have to say though, those pesky mosquitoes buzzing around, trying to bite me, send me running indoors to safety more often than not!

I don't know what it is about me, but I must have pretty tasty blood because I get eaten alive. What I want to know is why mosquito bites itch so much!

Did you know that it's only female mosquitoes that bite you? They eat mostly nectar, but when it's time to make eggs and lay them, they need to eat protein (aka - your blood). When the mosquito stabs her needle-like mouthparts through the skin of her victim, she injects her saliva, teeming with digestive enzymes and anticoagulants to help her drink more quickly. Your body sees that as an enemy and produces histamine to ward off infection. That little pink bump left on your skin is an allergic reaction to the mosquito's saliva.

Fit's Tips: After you realize that you've been bitten, try with all your might NOT to scratch that annoying itch - it'll only make it itch and swell more. Wash the area with soap and water, then apply calamine lotion, cortisone, or any other anti-itch cream to the infected area. An ice pack may also help.

If you have any other remedies for dealing with itchy mosquito bites, tell me below.

I'm a huge fan of making the "X"in the bite. It does work, but sometimes you need to do it over again. kerneschick - I'll have to try that with the dryer sheet. I heard that keeps mice away too (if you have a problem with that).

okay how about avoiding being bit altogether? Grab a Bounce dryer sheet and leave it in your pocket (fresh out of the box), it keeps the mosquitoes off! Also, vanilla extract works. Dab some on with a cotton wonders!

My husband taught me this... and it will sound crazy, but it does work!!! :) After a bite, when it starts to itch, use your thumbnail and press a cross directly over the bite. The deeper the better... How does it work? My theory is that it's the same as using that little electric TENS unit to bypass pain after surgery. It seems that the brain only processes one pain from an area at a time and itch is a form of pain... so the quick, little ouch from the self-inflicted nailcross hotwires the brain to focus on that instead - and it's much easier to take then that terrible longlasting :IRK: itch.

I hate bites... I used this stuff called mitigator once though, and it was like it never happened! You should try it. I order it off

I'm sitting here trying my hardest not to scratch the large red welts on my neck, arms, foot, forehead(!). They bite me in my sleep... I *hate* waking up to that buzzing sound. Argh!

ugh, i hate mosquito bites! they're so unbearable. and i'm highly allergic, so I get all these red bumps everywhere. And of course, they have to like my blood. If I'm out in a group and there's mosquitoes, then i'm the first one to get a bite - always.

It's mosquito country down here in Fl. I also get the large, red welts from mosquitoes and they suck!

I am also highly allergic and get giant red welts! Who knew there were so many of us! I use a cortizone cream from my allergist to stop the itching, but you can find some non-script strenght creams at the drug store.

I use Absorbine Jr. it stings if you've scratched, but stops the itch and heals them quickly.

Julieulie--- I get the same thing! I remember coming home from camp as a kid and my mosquito bites would turn into large red lumps that were really hard. They usually left a bruise when they went away.
