Mosquitoes generally feast on dweeb lords.

Several factors.

1. Genetic trait that attracts mosquitoes and biting insects.

2. Dietary sugars including no-sugar supplements.

3. BO and FO as well as high metabolism that produces significantly higher body temps and CO2 volume in breath.

BO = Body odour. FO = Foot odour.

Mosquitoes find their prey using three senses:
First by CO2, as mammals will be releasing it in big quantities (though they also bite reptiles). Second, by body smell, which as others here have mentioned, diet and genetics may dictate how it is affected. Third by shape (that’s when they are already there) and are trying to figure out where to stick it.

The first one is hard to fix, so for the second I’ll recommend icaridin or, if not available DEET, and in gel form not spray. DEET can be a skin irritant, hence why is less preferred.

Spray though is sometimes used when applying it to clothing, as it also may have your smell attached to it.

For the third one, I haven’t seen conclusive data but a lot of observational studies: from wearing light-colored ample clothing that doesn’t define the limbs to (I guess) wearing stripes like a zebra.

And a lifetime in humid climates like the Bayou.

I was once told by a doctor that everyone gets bitten about the same amount, but some people just don’t get a reaction.

I’ve definitely heard there’s a genetic element where some people just smell or taste yummy to them. I don’t have any research or anything tho. From personal experience, I think I get bitten more if I’m eating much sugar, or drinking alcohol, possibly because of a slightly higher body surface temp, or smell/taste different with more blood sugar.
