How to Make a Homemade Bed Bug Killer Spray With Vinegar
No one wants to discover bed bugs in their home. If you've ever experienced the itchy red rash those critters cause, you'll want to be rid of them as soon as possible. But can you kill bed bugs using what you already have in your kitchen? Vinegar often gets touted as a natural bed bug remedy; does it actually work?
The good news is that, yes, spraying vinegar directly on bed bugs can kill them because vinegar is a strong acetic acid that can disrupt an insect's nervous system. While this home remedy is safe and effective, it is not a standalone treatment, meaning you won't be able to eradicate a bed bug infestation with vinegar alone.
In this article, we'll explain how to use vinegar as a natural ingredient to get rid of and even ward off bed bugs until you can come up with a long-lasting solution.
How to Make and Use a Homemade Vinegar Bed Bug Spray
Homemade vinegar remedies for bed bugs are not pesticides, but they are much safer and will work early in an infestation.
Here's how to make a vinegar bed bug spray and use it effectively:
-
Purchase white vinegar, such as the Heinz Distilled, Walmart, or Kroger brand.
-
Fill an empty spray bottle with vinegar. You can use ULINE bottles, UPC bottles, or something from your local Dollar Tree. Tighten the lid securely.
-
Soak the perimeter around the infested area with the vinegar, including cracks and crevices in the walls and tight spaces underneath and between furniture. This way, when you spray the bed bugs, they will scatter into areas soaked with vinegar and die there.
-
Spray the vinegar directly onto the bed bugs to kill them on contact or send them running into nearby areas you just treated with vinegar.
-
To prevent further infestation, soak all infested surfaces, including windowsills, walls, furnishings, mattresses , and carpets . Spray the surface as well as the corners and undersides. You will need to do this every week for several weeks to see a reduction in bed bugs.
Health Warning
Never mix vinegar with bleach. This will cause toxic chlorine gas that can harm your health.
How Long Does It Take Vinegar to Kill Bed Bugs?
While vinegar may not kill bed bugs instantly , it does get pretty close. Many sources report that vinegar will kill bed bugs within minutes of contact, depending on the age or life stage of the bug that has been sprayed.
Pros and Cons of Using Vinegar on Bed Bugs
| Advantages |
Disadvantages |
|---|---|
| Can be used for short-term relief. The acidic content of vinegar is strong enough to disrupt their nervous systems. |
The smell is terrible and long-lasting. |
| It is cheap and available almost everywhere. |
You might not kill bed bugs completely but only push them into hiding. |
| This method is very safe. You can spray as much as you need and no one will be harmed as they would with toxic chemical sprays. |
Some furniture could be damaged due to the low pH of vinegar. |
| It is safe to use in homes with children, dogs, and cats. |
May be toxic to some reptilian pets. |

It will have little effect when there is a major infestation. |
Potential Results of Using Vinegar
Read the comments section below to see the results other readers have seen. The majority of readers agree that vinegar isn't as powerful as Hot Shot (which I've reviewed) , Bed Bug Bully, or JT Eaton, but it's an effective, albeit slow, way of killing bed bugs over time.
If you are waiting for a pest control professional to come to treat your home or for bug spray to arrive in the mail, vinegar will buy you some time.
The Results of My Experiment
I obtained a couch from someone with a bed bug problem, and a man with a barn was kind enough to let me do my vinegar experiment there. Here is what I did, and these are the results of that experiment:
-
We used a 100% solution of pure white vinegar. We filled spray bottles and soaked every inch of the couch. Then we used paper towels to wipe up the excess vinegar and dead bed bugs. This won't work if you can't get every crack, crevice, and surface. (Remember to wear gloves and avoid touching bed bugs because they are stinky, and they may seep blood when they're dead.)
-
This took three people four hours, but the results were promising. We observed only one small bed bug a week later. We missed the eggs, however. Vinegar has nearly no residual effect and does not work on eggs.
-
We learned that in order for this to work as the sole treatment, you will need to use gallons of vinegar and reapply every five days, which is not practical because it reeks.
-
We also observed bed bugs running away from the couch. One way to kill these bugs after they scatter is to soak the perimeter of the object you are about to spray with vinegar before. Spray around baseboards and windows. Take down curtains and wash them. Spray your TV stand and bookcases . Finally, spray the infested item last. This way, when they try to run, they are going to run into more vinegar.
Other Natural Ways to Eliminate Bed Bugs
There are several other natural DIY ways to get rid of bed bugs without an exterminator , and below are some of the methods that have worked for people.
-
Use caulk to seal cracks:Bed bugs live deep inside walls, so sealing with caulk denies them an easy place to hide, and it will prevent them from coming into your home via spaces in the walls.
-
Vacuum:Vacuum everything. Bed bugs tend to hide under furniture and lay their eggs on hard surfaces with crevices. Vacuuming up the eggs and the bed bugs themselves will significantly reduce their numbers.
-
Clean your entire house:Bed bugs are attracted to clutter, warmth, and carbon dioxide, so de-clutter the room by removing unnecessary items and putting things away neatly.
-
High heat:Bed bugs love to cozy up and hide in fabrics but will die when exposed to high heat, so throw all fabric items (i.e., sheets, pillows, rugs, curtains, stuffed animals, etc.) into the washer and wash on the highest heat setting. This will kill them immediately. Some people swear by using steamers to effectively get rid of bed bugs.
-
Use diatomaceous earth (DE):For items you can't toss into the washing machine, use DE. Diatomaceous earth kills bed bugs by tearing through their bodies . Sprinkle your mattress, soft furniture, and carpet with DE, leave it for a few hours or even a day, and then vacuum it all up.
-
Spray with alcohol:Like vinegar, rubbing alcohol can kill bed bugs on contact. It is a stronger chemical, though, and is not healthy for humans when inhaled.
How to Treat Bed Bug Bites Naturally
While white vinegar works better as a bed bug repellent, apple cider vinegar (ACV)is what you should use to treat the bites. Most people report intense itching after being bitten, but the low pH in white vinegar is too abrasive to treat the itching. ACV is milder and has antiseptic, antifungal, and antibacterial properties.
Recommended Brands:
-
Bragg Organic Apple Cider Vinegar
-
Walmart Great Value Apple Cider Vinegar
-
VitaCoast Organic Apple Cider Vinegar
-
Trader Joe's Organic Apple Cider Vinegar
How to use it:Apple cider vinegar is all-natural and healthy. An apple a day will keep the doctor away, and applying this type of vinegar will keep the itching away. The best way to use this anti-itching treatment is to apply the ACV to a cotton ball and apply it directly to the bite.

Vinegar Is Not a Long-Term Solution
Using vinegar is not a good long-term solution for bed bugs. I understand that some people have no other choice but to use this method, but I recommend you do whatever it takes to come up with the funds for professional help.
Remember: you are not alone. Do not be ashamed and try to hide an infestation. Face it, and do whatever it takes to eliminate the bed bugs.
