I am an evolutionary biologist that actually uses bed bugs as a model system to study a variety of population genetic and evolutionary questions. AS such, I have a bit of experience with them. I will make two comments. The later first - No, they will not harm your snakes. They are largely cued to mammals, therefore will feed on cats, dogs, rabbits, etc. However, humans are the primary host (of the human-associated lineage that is). The second point, and one you will not like to hear. You will not get rid of them yourself I am afraid to say. We work on a variety of questions, one being insecticide resistance. We are yet to find an actual field population that can be killed using the bed bug bombs and treatments you fine in big box stores, hardware stores, etc. Living in an apartment building, these are likely coming in from a neighbor (above, below, or side). The apartment management should pay for actual treatment. Simple ways for you to help reduce numbers before they get out of control, are to use climb up monitors under the legs of your bed (http://www.arbico-organics.com/produ...Fca6wAodmeQC0Q). Simple, cost effective, and extremely efficient at reducing numbers. Use these also for your sofa and chairs. Second, reduce clutter to zero. Bed bugs will hide in cracks and crevices, so magazines, pizza boxes, whatever, all act as hides for them to multiply, and that is something they do very effectively.

Good luck, but if you entered an apartment and found these, your apartment management company needs to treat these.
