Rubbing alcohol frequently surfaces as a popular, quick-fix solution for dealing with bed bug infestations, promising an easy and accessible way to tackle these troublesome pests.
But does rubbing alcohol actually work at killing bed bugs? The answer is more nuanced than a simple yes or no.
Does Rubbing Alcohol Kill Bed Bugs?
Most rubbing alcohol products contain either 70% or 91% isopropyl alcohol. According to laboratory studies conducted by Rutgers University, a direct spray of these alcohol solutions was only able to kill up to 50% of bed bugs.(ref)
This relatively low efficacy indicates that while rubbing alcohol might kill some bed bugs on contact, it is far from a comprehensive solution.

How to Use Rubbing Alcohol to Kill Bed Bugs
If you choose to use rubbing alcohol as part of your bed bug control strategy, follow these steps to minimize risks and maximize effectiveness:
1. Gather Supplies
- Rubbing alcohol (70% or 91% isopropyl alcohol)
- Spray bottle
- Gloves
- Protective eyewear (optional, but recommended)
2. Prepare the Area
- Remove or cover any items that may be damaged by alcohol, including electronics, fabrics, and furniture.
- Ensure the area is well-ventilated to reduce inhalation of fumes.
3. Mix the Solution (if Needed)
- For direct application, you can use rubbing alcohol as is from the bottle. There is no need to dilute it.
4. Apply the Alcohol
- Lightly spray the affected areas, including bedding, mattress seams, bed frames, and other hiding spots. Ensure you apply it directly to visible bed bugs and their eggs. Plus, avoid soaking the areas; a light misting is sufficient.
5. Allow to Dry
- Let the alcohol dry completely to help reduce the risk of fire and ensure you have covered all areas where bed bugs may be hiding.
6. Repeat Application
- Since rubbing alcohol only kills bed bugs on contact, you will need to repeat the application regularly, especially if you continue to see signs of bed bugs.
7. Monitor & Inspect
- Continue to monitor the affected areas and inspect for any remaining bed bugs. Consider using additional methods or consulting a pest control professional for a more comprehensive approach.
8. Dispose of Materials Safely
- Dispose of any contaminated materials or protective gear in a safe manner. Ensure that used spray bottles and clothes are discarded properly.
Alternative Ways to Kill Bed Bugs Naturally
If you’re looking for natural methods to address a bed bug infestation, there are several options you can consider. While these methods may not be as effective as professional treatments, they can help reduce the number of bed bugs and complement other control strategies:
1. Heat Treatment
Bed bugs are sensitive to high temperatures. Washing infested bedding and clothing in hot water (at least 120°F or 49°C) and drying them on the highest heat setting can kill bed bugs and their eggs.
Using a steam cleaner with a temperature of at least 130°F (54°C) can effectively kill bed bugs on surfaces like mattresses, carpets, and upholstery. Move the steamer slowly to ensure the heat penetrates deep into the fabric.
2. Cold Treatment
Bed bugs can be killed by exposing them to freezing temperatures. Place infested items in a freezer set to 0°F (-18°C) for at least 4 days. This method works well for items that can be safely frozen.
3. Diatomaceous Earth
Diatomaceous earth is a natural, non-toxic powder made from fossilized diatoms. Sprinkle it in areas where bed bugs are known to hide. The powder dehydrates and kills bed bugs by damaging their exoskeletons. Make sure to use food-grade diatomaceous earth for safety.
4. Essential Oils
Some studies suggest that oregano oil may have insecticidal properties.(ref) High concentrations of citronella oil have also been reported to have some effectiveness against bed bugs.(ref) For each oil, mix a few drops with water and apply it to infested areas.
5. Vacuuming
Use a vacuum with a HEPA filter to thoroughly clean areas where bed bugs are present, including mattress seams, carpets, and upholstery. Dispose of the vacuum bag or clean the canister immediately to prevent re-infestation.
6. Neem Oil
Neem oil has natural insecticidal properties. It has been used for centuries to control pests and diseases.(ref) Mix neem oil with water and a mild soap, then spray it on bed bugs and their hiding spots.
When to Call a Professional
Calling a professional is recommended when dealing with severe, persistent, or widespread infestations, especially when DIY methods fail or when the problem extends into other areas of your home.
Professional pest control services offer advanced solutions, comprehensive treatment plans, and can address the issue more effectively than most home remedies. If in doubt, it’s often best to consult with a pest control expert to ensure a thorough and effective resolution to the bed bug problem.
