does cologne attract bugs and mosquitos?

Answer 1

Bugs yes, mosquitoes no.

Bugs like bees and flies are attracted by sweet smells.
The only thing a female mosquito is looking for is the carbon dioxide in your breath.

Bugs can be attracted by a wide range of things. There is a plant that blossoms like and smells like a pile of manure just to attract flies for pollination. A wide range of smells could have a wide range of effects on insects.

I have seen a lot of bees hanging around soda cans, because of the sugar. I have even known a guy who got stung, in the mouth, when a bee fell into his soda can. So if it smells like sugar then the bees and flies will come.

The female mosquito is missing a protein that it needs to create her young. Otherwise she feeds off of flowers like male mosquitoes do. To make the protein requirements to reproduce the female mosquito needs fresh blood and they are adapted to finding it. One adaptation is that they can "see" CO2 in an animal's breath. All animals exhale CO2, and only living ones continue to breath. So if it is exhaling CO2 there is an extremely good chance that the female mosquito can get the blood and the protein in it that she needs in order to breed.
