Repeat the process twice a day for a week to get rid of any water bugs that are in your household. Later on, do it once every two weeks in the most vulnerable areas to prevent the cockroaches from coming into your household again.

Diatomaceous Earth

This natural product is a very simple home remedy for water bugs. The application is quick, but you need to make sure that you use gloves to protect the skin on your hands. It’s also advisable to cover your face with a mask for the time of the diatomaceous earth application.
Simply sprinkle some diatomaceous earth in the places where you usually see cockroaches. Leave it for three to four hours, then wipe it off with a wet cloth, obviously still wearing protective gloves. Diatomaceous earth damages the outer shell of the bugs and kills them very effectively.

To boost the results you can also sprinkle some of the product around the house once a month and just leave it there. It will form a permanent barrier against cockroaches trying to enter the house through the windows or the door.

Hot Water

If you know where the nest of the water bugs is, you can give them a hot (or even boiling) shower. Take a medium sized pot and fill it with tap water. Put it on the heat until it boils, then pour the hot water over the nest of the water bugs.

Repeat the process twice a day. Make sure you protect your hands with kitchen gloves when you hold the pot. Water bugs do not tolerate very high temperatures as their outer shell starts to crack. Also, high temperatures kill the small water bugs so their amount will be smaller and smaller with time.


Alcohol kills bugs and damages their eggs. It can be used just like vinegar, sprayed from a bottle onto the areas where water bugs can be found. Fill a spray bottle with alcohol. The stronger it is, the better. Spray it over the floors, corners, at the entrances and the windowsills.

Leave it on to dry and repeat the process every day for at least a week. Alcohol will dry out the fungus, making the damp areas less inviting for water bugs. It will also damage the eggs of water bugs. Once you get rid of the cockroaches, do this treatment once every two weeks as a means of prevention.

Baking Soda and Powdered Sugar

The mix of these two ingredients is another simple and effective method of exterminating water bugs. Take equal amounts of both – the quantity will depend on the amount of areas you want to cover. If you know where the nest of the water bugs is, it’s enough if you mix 100 g of baking soda with 100 g of powdered sugar.

Sprinkle the mixture over the areas where the water bugs have their breeding spot. It will trigger a reaction from their legs and eventually will kill them. Cockroaches also bring this mixture on their legs and shells into their nest and this way they damage some of their own eggs before they even pop.

This method takes some time, but is very effective. Sprinkle the mixture of baking soda and powdered sugar in the same areas every three to four days for a month and you will get rid of the water bugs from your household for a long time.

Garlic and Soap Spray

The mixture of garlic and soap disinfects the areas where water bugs walk and damages their eggs and shells. Garlic acts as a natural water bug repellent and a disinfectant due to its antibacterial, antiviral and antifungal properties. Take six to seven cloves of fresh garlic. Peel them and cut them finely, then add to a cup of boiling water. Leave it on the heat for twenty minutes, then remove the cloves and bin them.

Let the garlic water cool down a little, then pour it into a spray bottle. Add two teaspoons of liquid soap, close the bottle and shake it so that the liquids mix well. Spray the mixture under the sink, in the bathroom and the kitchen, over the edges of the floor, over windowsills and doorstep and wherever you noticed any cockroaches.

Garlic, Onion and Cayenne Pepper

Just the thought of these three ingredients mixed together brings a powerful image to your head and the taste buds. In fact, this mixture is so powerful that it kills water bugs almost instantly. To prepare this effective home remedy for cockroaches, peel one large onion and six garlic cloves.

Put the ingredients into a blender, add a tablespoon of cayenne pepper and two cups of water. Blend everything well and leave overnight. You can either use the mixture as is and pour small amounts of it close to or over the nests of water bugs. you can also strain the mixture and use only the liquid, applying it over surfaces with a spray bottles.
