There are a variety of do-it-yourself options for killing cockroaches. Some of the more well regarded of these are listed below. Try one at a time, or try them all.
Use cockroach bait.
Cockroach bait is either housed in a childproof case or applied as a gel and contains a slow-working poison mixed in with an attractive (for cockroaches) food. The roaches eat the poison and bring it back to the nest, where it eventually kills all the roaches. Place the bait in an area where you know cockroaches will encounter it.
Use cockroach traps.
Cockroach traps lure cockroaches in and then trap them with an adhesive. Get several of these, and place them wherever cockroaches are known to frequent.
Use water jars.
A simple and effective homemade way to lure and trap roaches is with a jar placed next to a wall, allowing the roaches to get in, but not escape. Any bait can be placed in the jar, including coffee grounds and water, but it also works with just plain water in drier climates.
Apply a liquid concentrate.
Liquid concentrates, once the exclusive domain of professional exterminators, are now being made for use by the public. The concentrate is a poison or deterrent chemical that is diluted with water and then sprayed, wiped, or mopped onto just about any surface. Concentrates can be particularly effective providing protection against re-infestation, as they usually deter roaches for 1-2 weeks or more.
Use a simple solution of soap and water.
This, to some, is the easiest thing to do. Just make a light solution of soap (bath soap is fine) and water. You can splash this, spray this or just throw this on the roach. Just a little water will do , even 2 or 3 drops can kill, if used effectively. Ensure that it makes contact with the roaches head and lower abdomen (its belly if you can turn the roach over). The roach will run or try to run, but will suddenly stop and die or be almost dead in one minute. It is best to throw it out as soon as possible, as it may revive. This happens because the roach breathes through its skin. The soapy water forms a thin film on the breathing pores, and effectively blocks them (surface tension), causing the roach to suffocate to death or to near death, although it could recover if the water dries up or has not touched a large percentage of its body. Try this and you will have amazing results for free.
