How much yeast is necessary to produce the same amount of carbon dioxide that I exhale? I think I might have bed bugs. I read that bed bugs are attracted to $\ce{CO2}$ and heat, I also know that yeast produces $\ce{CO2}$ as a waste product. Knowing that, I did some research and found this article on intructables.com which creates a "trap".

My gut instinct is that a 1/2 teaspoon of yeast will not produce anything close to the amount that a person exhales, but I don't know My question is, how much yeast would I need to create the same amount of $\ce{CO2}$ that I exhale on average in a day, per day?

What I know so far:


We exhale $\pu{0.02 m^3/h}$ while resting or low activity (Oscar W. Richards and Florence W. Haynes, Plant Physiol. 1932, 7 (1), 139–144.)
This graph (Figure 3 and 4 of above citation) shows the average $\ce{CO2}$ production per minute by yeast, but I don't know enough about chemistry to know what the units are or how to convert them to something useful (in my case, "useful" would be I need to buy x grams of yeast).


The trap definitely works as I've caught 2 in 24 hours. However, catching them isn't my interest (I wouldn't be able to get rid of them all with a trap). 


However, please don't be distracted by the bugs. The bugs themselves aren't the problem of this question; I'm trying to determine the quantities. I'm fairly naive when it comes to chemistry, but in my mind this shouldn't be a hard problem to solve. Unfortunately, I don't know how do the conversions or read the paper's to arrive at the answer but I'm still actively trying to figure this out.
I think this is a chemistry question, so I will answer it here.

First, I would question whether the amount of $\ce{CO2}$ is relevant or the concentration (or if more convenient, partial pressure). There is no way for the bed bugs to integrate over the entire trap vs. the bed. If you have a concentration gradient from bed to trap, it should work.

Second, yeast is a catalyst. The amount of $\ce{CO2}$ made depends on the amount of available food (the yeast will multiply to keep up). In the simplest terms, if you want the yeast to produce as much $\ce{CO2}$ as you do, you have to feed it the same amount of food that turns into $\ce{CO2}$. 

Because yeast and humans have a slightly different diet, you have to interpret "same amount of food" a bit. In human metabolism, all carbon from foods with calories (i.e. not fiber) is used in biosynthesis or ends up as exhaled $\ce{CO2}$. In an adult who doesn't gain or lose a lot of weight, you can estimate the amount of $\ce{CO2}$ produced from the amount of food taken in. In yeast metabolism, depending on the conditions, either most carbon turns into $\ce{CO2}$ (when there is plenty of oxygen) or into ethanol (when there is a lack of oxygen). For bed bug traps or baking, you want the former, while for brewing, you would want the latter.

For practical purposes, though, I think the total amount of $\ce{CO2}$ is moot (see my first point). As long as you have a source of $\ce{CO2}$ in the trap and remove the source of $\ce{CO2}$ in the bed (i.e. sleep elsewhere) and keep the room warm, there should be a nice $\ce{CO2}$ concentration gradient for the bugs to follow.
