I believe they all follow trails of your breath, which is why they can be reliably found above your bed when inside

So its likely about how that smells

Or other trails toward you, while they probably would enjoy your blood in actuality even if they think they’re detecting something related to how the meal would taste or its nutrition levels by proxy

Let me know what you all know!

> So its likely about how that smells

I thought the theory was that they follow the CO2 we exhale.

Yes thats the one, what word would you like to use for that sensory molecule detection

There is still some difference in who they choose to follow or act upon so I’m grasping for where that difference is. Could be something alongside the CO2

Humans exhale all kinds of stuff aside from just CO2, including moisture and other metabolic byproducts depending on what you’re eating. Probably some bacterial metabolic products from our mouths too.

I guess I’m less into the semantic difference between “smell” and “detect” and more whether it’s the CO2 they’re following or something else we exhale regularly.

Yeah I’m curious too, I think thats the right direction to research
