[editor: We have not tried this but have seen it a number of times on the Net. It seems worth trying, if you have a problem. Like everything be cautious, but we felt that if it does work, it should be shared. Obviously you need to keep a clean home and take out the kitchen trash every night]

Here is the recipe which will end your problems with the cockroaches:
First you need to take 1 raw egg yolk and put 30-50 grams of boric acid powder in it. Mix until you get solid mixture. From this mixture make balls with a diameter about 1cm. Wait until gets dry for about an hour and pour them all over the house in visible places and corners.
Make sure that the kitchen and the bathroom have special attention. Do not forget that the place should be visible, not from your point of view but from the point of view of the insect. Parts of shelves, racks, closets, kitchen cabinets too and all that is above your eyes.
This interesting ball disguised with boric acid, the cockroaches will not feel but she will come out to it from curiosity. When the cockroaches touch the ball with its mustache will die or it will have infernal itching. It will not be able to warn its other brothers insects because it will be unable to move.
These balls are harmless to pets and humans so they can be safely placed in the house or apartment in which small children, dogs or cats live.
After 3 to 4 weeks you will clean every day an enormous amount of dead bugs. Would the bugs disappear forever? If after 6 months of re-occurrence, the females may be able to lay eggs and hatch new generation, but the method of fighting is the same.
Sometimes the cockroaches may come from your neighbors where they tried to poison them. But if your balls are in the right place you should not worry, as they come running they will escape immediately.
Boric acid is not toxic and it is used for disinfection. If you can’t find boric acid in powder, use 3 percent of boric acid solution which is sold in every pharmacy at a cheap price.
