Things You'll Need
German cockroaches are one of the most common of the cockroach species. The cockroaches feed off almost any type of food and usually live in dark, humid places. Once German cockroaches begin to appear in your kitchen, you should exterminate them immediately. German cockroaches breed relatively quickly and lay multiple eggs per capsule. Eliminating German roaches in your kitchen may not take much effort, but keeping them from reappearing requires more effort. Once you have freed your kitchen of the pests, keep your kitchen clean to prevent them from coming back.
Set up traps. Put down sticky cockroach traps in areas such as inside your cabinets, on your counters, under your dishwasher, range or refrigerator and in the pantry. Place the traps along the baseboards and in corners. Once the German cockroaches walk on the traps they will become stuck to the surface and you will be able to monitor the areas of infestation. Finding the popular locations of the German cockroaches will help you to eliminate them. When you pick up the traps, check if there are holes in the foundation of your home that they may be entering from. If there are holes, be sure to seal up the holes as soon as possible.
Clean your kitchen. German cockroaches are attracted to food, compost and garbage. If you leave open food containers on the counter overnight, dirty dishes in the sink or crumbs and spills on the floor, cockroaches may begin to show up in your kitchen. If your kitchen is clean, they will not have anything to get into. In your pantry, keep chips, cereal and other snacks in containers with tight-fitting lids. Dispose of trash on a daily basis, unless you have a trashcan with a tight-fitting lid.
Set off a bug bomb or use a spray pesticide. Both chemicals can be toxic to both humans and animals so read the instructions and cautions carefully before use. If you choose to do a bug bomb, purchase a bomb that exterminates German cockroaches. Read the instructions carefully and depending on the size of your kitchen, you may need to use more than one bomb. Remove all food items or place them into your refrigerator before setting off the bomb. If you choose to use a pesticide spray, read the instructions carefully and then spray along baseboards, inside cabinets, in corners and dark areas in your kitchen.
