17 Effective Ways to Get Rid of Cockroach
1. Cut off water sources. Cockroaches must have a source of water. Depending on the temperature and their size, they can live for a month without any food, but no more than a week without water.
2. Clean your house thoroughly. A clean house is key to keeping cockroaches away, and the first place to start is the kitchen. Wash your dishes and put food away promptly after meals.
3. Hide your food. Keep food containers sealed, and don’t leave food out for extended periods. Don’t leave dirty dishes out overnight, and don’t leave fruit on the countertop.
4. Mop the floor routinely. This should clean up crumbs and sticky spots. Do not slop water against the walls; remember, they need water.
5. Take out the trash regularly. Have one trash can for food in your house. Don’t let it sit for too long. Use a trash can with a lid, rather than one that stays open.
6. Use store-bought 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 food (for cockroaches).
7. Try homemade cockroach baits. Mix one part powdered (not granular) boric acid (sometimes sold as a roach-killing powder, but often available in pharmacies), one part white flour, one part powdered white sugar.
8. Use a solution of soap and water. This is an easy way to kill adult roaches. Make a light solution of soap (bath soap is fine) and water that is thin enough to spray through a spray bottle. You can splash it, spray it or just throw it on the roach. Just 2 or 3 drops of a soapy water solution can kill a roach.
9. Use an insecticide spray. Get some insecticide that is labeled for use against cockroaches and contains Cyfluthrin or another insecticide as the active ingredient. Spray wherever cockroaches may be hiding or entering the house, including along walls, in cracks, and in vents.
10. Apply a liquid concentrate. Liquid concentrates, once the exclusive domain of professional exterminators, are now being made for use by the public.
11. Get professional grade pesticides. Look for a pesticide that contains Cypermethrin.
12. Use store-bought cockroach traps. Cockroach traps lure cockroaches in and then trap them with an adhesive.
13. Use water jars. A simple and effective homemade way to lure and trap roaches is with a jar placed next to a wall. This allows the roaches to get in, but not escape.
14. Use soda bottle traps. Take a plastic soda bottle and cut off the top where it curves. Invert the top and place it into the body of the bottle so that it acts like a funnel inside the bottle. Tape it into place around the rim.
15. Move yard debris away from the outside of the house. Make sure your woodpile is well away from the house. Remove piles of straw, leaves, clippings, and any other yard waste.
16. Seal the house to keep roaches from entering. Seal cracks in exterior walls to keep roaches out of the house by blocking their entrance. Seal cracks everywhere you can inside your house as well.
17. Set out preventative traps. Even if you successfully got rid of a nest, prevent a re-infestation by setting out traps that will kill roaches before they get out of control.
