The best advice is easy; clean up. If there is nothing for the roaches to eat, they have no reason to come into your house. You can also clean up any wet much and wood outside your home.
The next tip for prevention is exclusion. Make sure they cannot get into your home. You can do this by using weather stripping, caulking around windows and doors and pipes and electrical wires that enter your home. When it comes to roaches, an ounce of prevention is priceless.
When you want to get rid of water bugs or roaches in your home, there are many choices. A wetable powder is perfect to spray on the inside around baseboards. You can choose a synthetic or a bio pesticide. The bio pesticides can be very effective and possibly safer to use in your home.
The best way to attack roaches in the home is with a dust. A boric acid based dust is a fantastic roach killer and boric acid is safe, having only half the toxicity of table salt. Dust will disrupt a water bug’s digestive system when it is ingested. When using dust, be sure to get in all the cracks and crevices near your baseboards and floor.
Another option for killing water bugs is essential oil. Water bugs or roaches do not have lungs. They have breathing tubes that go directly to the blood. Essential oils will clog up the breathing tubes of the roaches.
Attack the outside of your home with time release granules. These will take a month to break down and will kill the entire roach life cycle during that time. Granules which are Pyrethrum based are synthetic but are biodegradable and therefore not harmful to the environment.
With a little prevention and a few products you can easily keep your home free from water bugs.
