I understand your situation, this is no easy task. It will take some work, but you can get rid of a really bad German Cockroach infestation. Here is a repost on this subject -
It sounds like you have German Cockroach invasion. Actually, what we call a "serious infestation". Here are the 3 problems typically associated with ineffective german cockroach control -
Problem #1 - The #1 problem with German Cockroach control is that they lay egg capsules. In each egg capsule there can be 40-50 baby german roaches. In a month or so, these newly hatched babies can start breeding and each female can then start laying egg capsules. You see the problem here. You can kill the adults, but the babies or "nymphs" can grow so fast and breed so fast, that you never get control of the population. The population can literally explode and become uncontrollable in a short period of time, with mathematically, tens of thousands of german cockroaches hiding in every crack and crevice in the home.
Problem #2 - Synthetic pyrethroid spray pesticides and the "resistance" or immunity of the cockroaches towards these pesticides. Basically, many pesticides won't kill german roaches, they are resistant.
When dealing with a serious german cockroach population, spray's usually don't work. You have to use non-repellent baits and dusts, along with IGR's (growth regulators) to get control. A crack and crevice treatment using a flushing pyrethrum based insecticide is a must in this situation. CB80 is an example of a "flushing insecticide" that drives them out of cracks and crevices.
Problem #3 - Not enough time spent preparing for treatment and not enough time actually spent treating. Unfortunately, many pest control companies that pay their technicians on a commission basis, usually deliver ineffective results. The technician can't afford to spend the time required to do the job correctly. The minimal amount of time required to do a proper "german cockroach clean-out" for your home could be up to 3 hours. The follow-up treatments could take 1-2 hours each every 2-3 weeks until the roaches are under control. You can't just spray poison on the baseboards and cabinets and expect to get control.
German roaches live in kitchen and bathroom cabinets, and when the population gets bigger, they move into the other rooms of the house. If you are seeing them all over the house, then that is a sign of a fairly extensive german cockroach problem. This explains why you see them everywhere.
We have a complete page on how to get rid of german roaches here
Begin the treatment by using gel bait such as Maxforce Cockroach Gel placed into the cabinets and wherever you are seeing the roaches. Use small pea size placements and put it into the corners of cabinets, dressers, baseboards, cracks and crevices. Keep replacing the bait as the roaches eat it.
A good crack and crevice product for German roaches is Invader - This is what a lot of pest control companies use to kill cockroaches on contact. Works faster than RAID. It's a fantastic product. You basically have to treat almost every crack and crevice in the entire home. Especially around cabinets, paneling, etc.
A good Insect Growth Regulator or Sterilizer is Gentrol Point Source - place this under sinks in the kitchen and bathroom.
Dusts such as Borid (boric acid) need to be applied inside of plumbing areas inside walls, electrical switch plates, behind the refrigerator, washing machine, dryer, dishwasher, etc. A light application is all that is needed, the amount of dust of furniture, a light coating is all that is necessary. Use a good duster such as the Puffer Duster to do this.
I know this is lengthy, but there really is no way to go about doing an easy treatment for German roaches. Most professional pest companies would charge a minimum of $100 - $200 just for the initial treatment, and then a monthly charge of around $60 until the roaches are eliminated. So by doing it yourself, you are saving the cost of time and labor. I would estimate the average total time required to do this at about 6 hours, over a period of 3-4 treatments.
This is something you can do yourself, and we have the exact same products the pros use. Hope this helps.
