Would someone tell me why mosquito bites itch? Hi David - the going to sleep thing hasn't worked - SO :) according to wisegeek... Mosquitoes are a bit like flying syringes. Their large needle nose, called a proboscis, is ideal for quickly landing on a victim, withdrawing a bit of blood and then taking off for the next target. Individuals may not notice a mosquito bite initially, but within an hour or two after a bite, they may have raised red bumps that itch like crazy. When a mosquito bites, she leaves behind saliva that the body reacts to, causing a (usually) mild allergic response in the form of itchiness. Of course only the girlies bite :) and it's not personal... they've developed extreme sensitivity to CO2 in the air, and once a female picks up an increased concentration of it (from as far away as 75 feet) she flies back and forth through the CO2 plume until she locates her victim :) then it's YUMMY time... for her of course :) |

Would someone tell me why mosquito bites itch? Okay, I was going to ask what the larger ecological and evolutionary purpose was for the histamine response, but I suppose it just doesn't matter to them that we itch. I just wish they would take our blood and leave us not knowing about it, but there's no advantage to them in doing that.

Speaking of mosquitoes... http://wwlp.com/2014/07/19/deadly-mosquito-virus-reported-in-eastern-mass/ "Mosquitoes: we’ve talked about them for months, and for the first time this year mosquitoes have infected someone in Massachusetts with eastern equine encephalitis, or triple E." ~Sue~ |

Speaking of mosquitoes... That IS a disturbing development Sue :( I think environmental conditions are getting more and more favourable for these guys - well girls when it comes to being bitten of course - boys just suck on plant sap I think... not to mention the diseases they can carry. :/ |

Good grief! Used to have to rapidly re-submerge myself when swimming in different parts of africa when big things like that were hovering above the water - but they were NEVER that big! |

That thing, GAAAACK is right. The only bugs I worry about are small moths, I setup a text file to see how many moths are coming in and when, I've been doing this since the 18th of this month noting how many got in and that I got rid of, since the 20th I've seen none thankfully. 1 on the 18th and 2 on the 20th and on the 20th they were separated by at least 8 hours from each other.

That thing, GAAAACK is right. Vic, got invaded by moths a couple of summers ago. I hate bugs. :( Took my vacuum cleaner out and killed those Mo*&*^% F@#$%$#. My cats helped also. Only had a couple since then. Serial bug killer, Lynn |

Moths often come into your house with things like birdseed. If you buy birdseed, keep the whole bag in the freezer for about 48 hours to kill the moth larvae. ~Sue~ |

Moths often come into your house with things like birdseed. If you shh - don't tell anyone... I'm off topic... Julie... how big is a dwarf hamster? :) Got a bit cross with one of my cats last night. Normally when I hurtle across the room with my hands outstretched to save a daddy long legs or spider or moth or ladybird (you get the idea :)) my furries all scatter to the four winds. Not Jet last night... oh no! One big fat swipe of his paw and there was one very beautiful but very dead moth. He did have the grace to look slightly ashamed and did seem quite disappointed that it had given up playing so quickly... |
