Since I've been such a good host to these fleas, so many have moved in that I once in a while I might see one around. I've taken to catching them on pieces of tape and throwing them away (they are too small and too tough to crunch in your fingers). My girlfriend saw me doing this the other day and suggested that I should keep them in a jar (I suggested, in turn, that she should clean my apartment).
Anyhow, I took to her suggestion and have been catching fleas and placing them in a glass vial. Follows is everything you need to know to do it yourself.
Step 1: Get fleas
Make certain that she never brushes, cleans, or cleans up after it in any regard. It particularly helps if she doesn't give the cat flea medicine regularly. This will help increase your chances of getting fleas in your apartment.
