Can borax kill bed bugs

We know that dealing with bed bugs can be a nightmare. You’re trying to get a good night’s sleep, but instead, you’re constantly worried about these pesky pests crawling all over your bed. You’ve tried everything from bug spray to professional exterminators, but nothing seems to be working. So, you start to wonder: can borax be the solution to your bed bug problem?

Well, let’s take a closer look at this question and find out.

What is Borax?

Before we dive into whether or not borax can kill bed bugs, let’s first discuss what borax is. Borax, also known as sodium tetraborate, is a naturally occurring mineral that has been used for various household purposes for centuries. It’s commonly used as a laundry detergent booster, a cleaning agent, and even as an insecticide.

Does Borax Kill Bed Bugs?

Now, on to the main question: can borax kill bed bugs? The short answer is yes, borax can be effective in killing bed bugs. However, it’s important to note that borax is not a one-stop solution for eliminating a bed bug infestation. It works best when used in combination with other pest control methods.

Borax can be toxic to bed bugs when ingested or when it comes into contact with their exoskeletons. It works by dehydrating and ultimately killing the bed bugs. However, it can take several days for the borax to fully take effect, so it’s important to be patient and continue using other pest control methods in the meantime.

How to Use Borax to Kill Bed Bugs

If you decide to use borax to help with your bed bug problem, here’s how to do it:

  1. Start by thoroughly cleaning and vacuuming your home, paying special attention to areas where bed bugs are commonly found, such as the cracks and crevices of your bed frame and along the seams of your mattress.
  2. Once you’ve finished cleaning, sprinkle a thin layer of borax over the affected areas. Be sure to cover every inch of the area, as bed bugs can hide in even the smallest of spaces.
  3. Let the borax sit for at least a day or two to give it time to work its magic.
  4. After a few days, vacuum up the borax and dispose of the vacuum bag immediately to prevent the bed bugs from crawling back out.

Other Tips for Getting Rid of Bed Bugs

In addition to using borax, there are a few other things you can do to help eliminate a bed bug infestation:

  • Wash all of your bedding and clothes in hot water to kill any bed bugs that may be hiding in them.
  • Use a high-quality bed bug spray to kill any remaining bed bugs.
  • Consider using bed bug interceptors, which are small cups that you place under the legs of your bed. These cups create a physical barrier that prevents bed bugs from crawling up onto your bed.
  • If the infestation is severe, you may want to consider hiring a professional exterminator to help get rid of the bed bugs.


In conclusion, borax can be effective in killing bed bugs, but it’s important to use it in combination with other pest control methods for the best results. By following the steps outlined above, you can effectively eliminate a bed bug infestation and get back to enjoying a peaceful, bug-free sleep.
