Dear 100 Hour Board,
Just found out my apartment has fleas. My feet have so many itchy bites. Encouragement?
I don't know if this is the encouragement that you're looking for, but here goes something:
You've got this! You can do it! GOOOOO Jane!
Hope that helps!

P.S. But really, unless you are in a country where this is unavoidable, this is NOT something you have to put up with. If you're renting, talk to your landlord and get moved to another apartment. If it's your own house, see Squirrel's answer.
I don't have much to add here as far as what you should do, but if you are going to buy a bug bomb, I cannot stress enough that you should follow the safety instructions exactly and wash all the fabrics, and vacuum all the drapes, carpets and cushions in your home after the bug bomb is done. Air out your home for the amount it says on the label, and if possible-- even longer. Please leave your house-- preferably your block after you set them off. Yes, the safety instructions should be sufficient, but it can't hurt to be extra cautious. I've heard some really sad stories of young children dying because they were playing outside within four feet of their house while a bug bomb was set off and they died because they didn't notice the smell, and breathed it in for several hours. The tragedy could have been easily avoided if the safety label had been followed exactly.
Also, please please please if you buy a bug bomb, buy enough for the correct square footage of your living space so that it actually works, and check to make sure that the bomb you are buying specifically states that it is for fleas. I work at a home improvement store over the summers, and I cannot tell you the number of angry customers that have come back and complained to me when they bought the bug bomb that was on sale, instead of the one that targets their particular pest, and it didn't work.
If you do the above, everything should work just fine.
