Bed bugs are tiny pests that can make life uncomfortable. They hide in mattresses, furniture, and crevices, feeding on human blood while we sleep. These pesky insects are hard to eliminate, which is why many people use rubbing alcohol as a quick fix. But what can you mix with rubbing alcohol to make it work even better? A 50/50 or 70/30 solution of alcohol to water is commonly recommended.
This blog will explain how rubbing alcohol works, what you can mix with it, and how to safely use it for killing bed bugs. You’ll also learn about its limitations and other solutions to handle bed bug infestations.
What Can You Mix with Rubbing Alcohol?

To make rubbing alcohol more effective and easier to use, it can be mixed with other ingredients. Here are some options:
1. Water
Mixing rubbing alcohol with water is a simple way to dilute the solution and make it safer to use. A common recipe is:
- 50/50 solution (equal parts alcohol and water)
- Or 70% alcohol, 30% waterÂ
This solution can be sprayed directly onto bed bugs and their hiding spots, such as mattress seams and baseboards.
2. Essential Oils
Adding essential oils like tea tree oil or lavender oil not only adds a pleasant smell but may also repel bed bugs. To make this mix:
- Combine 1 cup of rubbing alcohol with 1 cup of water.
- Add 10-15 drops of essential oil.
- Shake the mixture well in a spray bottle.
Remember, essential oils don’t kill bed bugs. They only help by deterring these pests.

How to Mix and Use the Solution

Follow these steps to make your own bed bug spray with rubbing alcohol:
Step 1: Dilute the Alcohol
Fill a spray bottle with a mix of rubbing alcohol and water. Use a 50/50 or 70/30 ratio.
Step 2: Add Essential Oils (Optional)
If you’re using essential oils, drop them into the spray bottle and shake well to combine.
Step 3: Spray Visible Areas
Spray the mixture directly onto:
- Bed bugs you can see.
- Mattress seams, bed frames, and other hiding spots.
Step 4: Avoid Overwetting
Make sure the area is damp but not soaking, as too much liquid can damage your furniture.
Step 5: Reapply Often
Rubbing alcohol evaporates quickly, so you’ll need to spray affected areas daily or more often to see results.
Safety Tips for Using Rubbing Alcohol

While rubbing alcohol is a helpful tool, it has some risks. Keep these tips in mind to stay safe:
- Flammability: Rubbing alcohol is highly flammable. Never spray it near an open flame or heat source.
- Ventilation: Use it in well-ventilated areas to avoid inhaling strong fumes.
- Keep Away from Kids and Pets: Store the spray bottle where children and pets cannot reach it.
- Protect Sensitive Surfaces: Alcohol may stain or damage certain materials. Test a small patch before spraying onto furniture or fabrics.
Limitations of Rubbing Alcohol
Even though rubbing alcohol kills bed bugs, it isn’t a complete solution. Here’s why:
- Only Works on Contact: It doesn’t kill hidden bugs or eggs.
- Short-Term Effectiveness: Alcohol evaporates quickly, leaving no lasting protection.
- Small-Scale Effectiveness: It’s useful for minor infestations but not severe ones.
For larger problems, you’ll need alternative methods or professional help.
