Roaches are yucky pests and are a health hazard. They multiple quickly and are difficult to get rid of once they have infested an area. Usually, roaches gain entry into your home from small cracks and crevices or from storing furniture, appliances or clothing for a friend or relative whose home has roaches. Roaches have a thick shell and can survive the toughest insect-killer products. They carry bacteria that can be transmitted to people. Killing roaches permanently is a difficult task, but it's not impossible. It requires concentration and preparation.
Clean your home thoroughly. Wash everything with soap and water. If you have a special type of surface, try Seventh Generation eco-friendly products; the eco-friendly way to clean.
Vacuum your house, using the appropriate attachment to reach cracks and crevices. Vacuum under sofa cushions to remove crumbs. Do this on a daily basis.
Look for cracks and crevices. This is where roaches nests are located.
Use Combat Platinum Roach Killing Gel. The roaches will eat the gel and die in the nest. Other roaches will eat them and die. The roaches and their nest are destroyed, and you have permanently killed the roaches.
Clean up any dead roaches you find.
