Tip 1: Repair the Plumbing Inside a Building
Cockroaches seek moisture, and when you have leaking water pipes or plumbing fixtures, the insects will enter a building to live in the walls. If the drywall, floor tiles or carpets in a building are contaminated with moisture, then you must clean and dry these items thoroughly.
Tip 2: Seal the Crevices and Holes Inside and Outside a Building
A cockroach can enter through tiny holes and crevices in a building’s foundation or around window frames. Use liquid caulking to fill the crevices and holes on a building’s exterior and interior surfaces. If there is a large hole, then use insulation to fill the space before sealing it completely.
Tip 3: Remove Clutter From a Building
When a building has a lot of clutter, you are more likely to have infestations of cockroaches. This variety of insect usually hides under cardboard boxes, piles of clothing and other debris. By making it difficult for cockroaches to hide underneath clutter, it is easier to eliminate the insects.
Tip 4: Make Boric Acid Poisonous Doughballs
It is possible to eliminate cockroaches with poisonous boric acid dough balls. However, it is important to place these dough balls in places where family pets or people cannot access the items. Use a disposable bowl to mix flour, confectioners’ sugar, boric acid and water with a plastic spoon. Wear disposal plastic gloves to roll the dough balls, and place these items in disposable aluminum pans. Place the aluminum pans with the dough balls in the top cabinets in a kitchen or other difficult to reach areas. The cockroaches are attracted to the sugar, but after eating the dough, the boric acid will dry out the insect’s internal organs, causing the vermin to die.
Tip 5: Use Essential Oils To Eliminate Cockroaches
Cockroaches don’t like the odor from peppermint and cypress essential oils. Fill a plastic spray bottle with water before adding 20 drops of cypress oil and 30 drops of peppermint oil. After placing the lid on the spray bottle, shake the mixture thoroughly before using it on kitchen countertops, walls, and baseboards to eliminate or deter dirty cockroaches. You can also spray this mixture on a building’s window screens or around doors to keep the cockroaches from entering a building.
