It’s been a hot summer and with that comes those annoying little insects with a high pitched whine, mozzies. Isn’t it interesting though how they seem to favour some people over others for their blood meals that result in excruciatingly itchy bite marks?
Scientists reckon about 20% of people are especially delicious for mozzies, and in this article we’ll look at a few of those factors make them so attractive.
About 85% of people secrete a chemical signal through their skin which indicates to mosquitoes which blood type they are. Mosquitoes favour secretors over nonsecretors and prefer blood type O more than type A with type B falling in between.
Mozzies find their victims by smelling their lactic acid, uric acid, ammonia and other substances expelled via their sweat. They’re also attracted to higher body temperatures. So if you’ve been sweating it out, you’re more of a target. Genetic factors also play a role in how much uric acid you secrete, so not too much you can do about that.
Scientist have found that drinking just one bottle of beer can make you more attractive to mozzies, although they aren’t sure why!
It is estimated that genetic factors account for 85% of the variability between people in their attractiveness to mosquitoes, and that's regardless of some of the other factors mentioned above.

We quite often say that our Ecomist Insect Killer with Natural Pyrethrins kills and “repels” insects.
In this month's Blog we're going to explore the repellant effects of pyrethrins a bit further.
This will remove any irritating saliva that still remains on your skin and help the bite to heal without infection.
Most mosquito bites do not hurt, and so you may not detect them for several hours. Icing the area helps control pain and swelling.
