Boric Acid

You can sprinkle boric acid powder in areas where you have seen water bugs. You should wear gloves when handling boric acid and keep it away from children and pets.

Essential Oils

Some essential oils, such as peppermint, eucalyptus, and tea tree oil, have insecticidal properties and can repel or kill water bugs. You can mix a few drops of essential oil with water in a spray bottle and spray it in areas where water bugs are present.

Sticky Traps

Sticky traps are another effective method to kill water bugs. They work by trapping the bugs when they walk over the adhesive surface. You can place sticky traps in areas where you have seen water bugs and dispose of them when they are full.

Boiling water

Pouring boiling water on water bugs is an effective way to kill them instantly. This method is best used for water bugs that are in areas where water can be safely poured without damaging surfaces or electronics.


Vacuuming can help to remove water bugs and their eggs from your home. You should use a vacuum with a HEPA filter and dispose of the vacuum bag outside your home to prevent the bugs from escaping.

How to prevent water bugs from entering your home?

Preventing water bugs from entering your home can be challenging, but here are some tips that can help:

Keep your house clean

Water bugs are attracted to food, so you need to keep your home clean and free of food debris. This means wiping down counters, sweeping floors, and storing food in airtight containers.

Seal cracks and crevices
