Each professional exterminator (or business entity) will have their own unique touch that they add to achieve the results they aim to get. They won't tell you what it is even if you pay them (unless you're a multimillionaire with spare cash to waste). They'll gladly come to service your home for a fee, but they won't disclose their secrets to you. That's not to say they won't offer you tips to help though because I'm sure most of them would be more than happy to help you out. I mean you are helping him/her/them out by giving them business.
Even if you can't uncover their secrets, you can follow what they would generally do when treating a cockroach infestation. Just follow what the generally do and although you won't to get the maximum results like they will, you’ll get it close enough.

For this task, you must use an insecticide that will stay effective for a prolonged period of time. You need to use man and insecticides because they're the only ones that will stay effective up to a month after the Initial spray. Natural stuff will deteriorate within hours after being exposed to light and oxygen.
After spraying the baseboards, you will also need to spray areas where roaches come through frequently. Learning more a bullet the roaches makes these areas easier to identify.
Then you will need to flush out roaches that are hiding in small cracks and spaces you cannot reach. An insecticide spray with a precision straw works great for this. The small straw lets you spray these very tight spaces with precision. You are also able to drill a small hole into the drywall and spray the insecticide into it.
Flushing them out will kill any that directly comes into contact with the initial flush. Any other that run out later will go through the insecticides sprayed first. Those will die as well. Keep in mind that the chemicals need to be sprayed again on a monthly basis. To get a good list of insecticides that the pros use check out this webpage.
