Chances are the entire population are german roaches. They go through several different life stages on their way to becoming an adult, and they look different somewhat than the adults.
Caulking may help some, but it will not control the population. It can be almost impossible to seal them out. Once they get inside, you simply seal them in.
IGR's take about 4 months to work. You will not see any immediate results.
Maxforce FC Roach Gel Bait is the best bait for german cockroach control. Gentrol or Gentrol Point Source is the best IGR. Point Source is easier to apply.
If there is a gap between the doorway and the floor, sealing it with threshold or sweep is always recommended, although this may not keep them out.
There is a complete list of things you can.
1) Take off all wall switch plates and electrical plates and "dust" into the walls with either Boric Acid dust or Cynoff Dust. Cynoff will give you an extremely fast kill as it is basically Demon WP in a dust form Borid will give you longer lasting protection. You can also mix the two together. Be sure to dust into the walls with a small duster such as the Puffer Duster. Don't make piles or clumps of dust. Dusting should be smooth so that the cockroaches will crawl into it. Also dust into walls around all plumbing penetrations.
2) Treat all cabinets - kitchen, bath and everything will Maxforce FC Gel Bait. Maxforce FC Gel Bait will kill cockroaches that eat it and will also kill cockroaches that eat the dead roaches. This is called a "transfer effect".
3) Use Point Source under all sinks. Just attach it to the side of the cabinet. Also hot water heater cabinets or closets.
4) Invader HPX gives an instant kill of exposed German Roaches. Shoot it into cracks and crevices and places where they could be hiding.
5) Get a good shop vac and suck up any live roaches and egg sacks. A good thing to do is to apply a little cleaning solution, lemon oil, etc to a layer of water inside the vac. That way, the roaches will drown and can't crawl out. It makes the place smell good too.
6) Spend at least a good 2 hours doing this on an "initial" treatment and in 2 weeks go back and check the bait and see if it is eaten. If so, replace it. Never spray any insecticide where you place the bait.
7) Traps such as the Victor Pheromone roach trap are designed specifically for german roaches. You can place them any where and monitor their movement.
Above all, use a dedicated effort. If you do all of this, you will get control. If you follow up every 30-60 days you will probably get rid of 99% of them in your unit.
If you have any questions, let me know.
