My friend once asked me to babysit his dog for the weekend. For weeks afterwards I tried all the products and techniques mentioned so you have my deepest sympathies.
Getting rid of fleas is tough, but obviously possible. First things first, remove any pest food/harborage. This means you need to vacuum every single surface that may have fleas, carpets, rugs, couches, chairs, etc. Use a high quality HEPA vacuum and empty the bag/canister immediately after and then spray down the vacuum and nozzle with a flea killer spray you can buy at Walgreens. Throw out any furniture/clothes/other harborage that you don't need, or remove it from the apartment and isolate it into plastic bags. You should then wash clothes in hot water, and keep all furniture wrapped in bags and out in the sun. (The temperature in the bags needs to be 100+ F, so you might want to use a heater of some kind- around 48 hours at this temperature should kill all the fleas)
Buy some Diatomaceous Earth and spread it all across the carpet and make sure it gets in deep into the fibers. Be sure to wear a mask while doing this. DE has very sharp microscopic edges (these sharp edges actually rip open flea eggs or cut up the fleas and this is what kills them) and these edges can cause lung damage if proper precautions are not taken. It's not toxic, per se, but it will irritate your lungs and respiratory precautions should be taken. Keep the DE in the carpet for 24 hours, and then vacuum. Repeat the DE and vacuuming procedure for a week/two weeks, taking care to clean the bag and spray down the vacuum each time. You may choose to spray the carpets and other areas of the apartment with sprays from walgreens as well each time.
The vacuuming and DE will kill off the fleas. You need to kill literally all of them, all at once or they will breed and come back with a vengeance. The vacuuming causes the eggs to hatch, (in addition to killing the live ones) and then the DE kills them as they move about.
How do you know you've killed them all? Easy: set up a paper plate filled with a little bit of soap and water and place it under a task/desk lamp somewhere in the corner or on the floor. Turn off all the lights at night but leave the lamp on. Fleas are attracted to the light and they will jump up and get trapped in the soap-water dish on the floor. Each day you should find less and less of them as you return to vacuum, and when you've had a week or so without any fleas, you can stop the eradication procedure and move on with your life.
As much as it probably hurts to hear it, you are sort of stuck for the time being. You need to be super diligent about this and go all-out with killing these fleas. Be extremely disciplined about vacuuming every day and using the sprays and DE to get every last flea. General cleanliness in the house and around will stop the problem from reappearing.
Good luck!
