How To Make Homemade Bed Bug Spray

It can be tough to eradicate bed bug infestation from your space, but it is not impossible. It is important to deal with these pests before they reproduce quickly all over your house. Here are some effective ways to terminate early infestation of bed bugs using the following homemade spray.

  2. Spray the solution directly on the bed bug or where you see the signs of its infestation. 
  3. Cover all the areas like bed crevices, furniture, windowsills, cushions, and every other place with bed bug signs. 
  4. Repeat the process every week until it permanently eradicates its existence. 

Even if it can kill the bed bug, it is not an effective way to eradicate the bed bug infestation in your space. Its effect is only good for early infestation.

Making Essential Oil Spray

Essential oil is popularly known for its anti-fungal, anti-bacterial, and antiseptic properties. Its potent smell can repel bugs like ants, spiders, cockroaches, silverfish, and bed bugs. Additionally, it is non-toxic and safe to use around humans and animals. 

If you want to make a natural spray without using harmful chemical insecticides. Making a homemade essential oil spray is the ideal solution.

Some of the effective oil to repel bed bugs from your space are:

  • Clove oil
  • Cinnamon oil
  • Peppermint oil
  • Thyme oil
  • Cedarwood oil 
  • Citronella oil
  • Tea tree oil
  • Lemongrass oil
  • Lavender oil
  • Neem oil
  • Oregano oil

Here is how to make a homemade spray using one of the above essential oils and apply it on bed bug-infested areas. 


  1. Fill the spray bottle with 30 drops of whichever essential oil you have and mix it with water. You can combine a few drops of other essential oil to make an effective bed bug repellent.

  3. Shake well before using it.
  4. Spray the mixture in every hiding place of bed bugs every night, one hour before bedtime.
  5. Apply it once a week for better results.

Applying Isopropyl Alcohol Spray 

Applying Isopropyl Alcohol Spray

Alcohol is an efficient method for killing visible bed bugs. Similar to diatomaceous earth, it can destroy the outer shell of bed bugs. The alcohol will dehydrate and ultimately kill the insect. The strong odor of alcohol also repels insects.

It is an inexpensive and effective way to kill bed bugs. But, it cannot kill bed bugs that are well hidden in crevices and gaps. It is only effective if you spray the alcohol on the bug and its eggs directly.

Caution: Isopropyl alcohol can cause respiratory issues when inhaled. It is better to wear a mask and gloves while applying it. Also, it is flammable; it is recommended to ventilate the room before starting the elimination procedure. 


  1. Vacuum the mattresses, linens, and furniture and clean the infected area.
  2.  Purchase rubbing alcohol and fill it in a spray bottle.
  3. Spray the alcohol in clothing, sheets, linens, furniture, and mattresses with rubbing alcohol. Do not forget the cracks and gaps the bed bugs might be hiding.
  4. Repeat to apply it every two weeks for better results.

Other Effective Ways To Eliminate Bed Bugs

Using Diatomaceous Earth

Using Diatomaceous Earth

Diatomaceous earth (DE) is a powdery white substance with sharp and abrasive edges. The DE harms the outer layer of shells when pests like bed bugs and other insects like sugar ants, roaches, and spiders come into touch with it. The bed bug’s exoskeleton keeps the body moist; if it is breached, the bed bugs will become dehydrated and die.

It would be best to use food-grade diatomaceous earth with extra precautions. Wear proper gear like a mask, Eyewear, and gloves. Inhaling the DE sometimes can cause allergic reactions in humans and animals. 


  1. First of all, steam clean the mattress, linens, and furniture. Make sure to dry the mattress or linens if they are wet. Vacuum your room, bed, and carpet.
  2. Look out for signs of bed bugs and where they might hide. They can hide in the side of your mattresses, in your bed cracks and crevices, around the furniture, windowsills, box springs, and anywhere in your room where there are gaps.
  3. Apply a thin layer of DE powder in the mentioned areas. Cover all the areas with the powder.
  4. Let it sit for a couple of weeks or longer if you want.
  5. Utilize a shop vac to wipe the DE powder from the space.
  6. Reapply the powder every week for effective results.

It takes a lot of patience to let Diatomaceous properly work. Even Though it can kill bed bugs within 24-48 hours, it takes time to make bed bugs walk through the powder. Therefore, it can take several weeks to show results. Also, it is not effective to kill the bugs’ eggs. You have to wait until the eggs hatch. 

Invest in Heat Treatment 

Doing Heat Treatment

Homemade sprays cannot help you if the bed bugs infestation in your space is huge. It would help if you had the solutions to terminate bed bugs’ existence.

Heat treatment is well known to eradicate bed bugs and their eggs from the house. When the temperature of a room is increased to 145 degrees Fahrenheit, bed bugs die immediately. The treatment needs to be done by a skilled technician and takes approximately 8 hours to complete.

Using Insecticide-Based Treatment

Using Insecticide-Based Treatment

If you want something more affordable than heat treatment, you can opt for the chemical-based treatment. You need to hire experts to use this method. Experts use insecticides to eradicate bed bugs and other long-lasting chemicals to prevent them from returning. 

But, the chemicals do not kill the bed bug egg. It is important to reapply the insecticides to eradicate the bed bugs permanently.

Prevent Bed Bugs From Coming Back

Even after using different tricks and methods, it is very difficult to wipe their existence permanently. The best thing to avoid bed bug infestation is to prevent them from luring into your space. There are several ways these tiny pests can find their way into your area. 

  • Be cautious while purchasing second-hand furniture. The previous owner might have given it away because of the bed bug infestation. 
  • Invest in protective covers for your mattress. 
  • Wash the washable items in the washing machine in a hot water setting after treating the pest. You can even soak the fabrics in hot water. 
  • While traveling, look out for bed bug infestation in hotels and motels. Never place your luggage near beds and furniture. 
  • Clean and vacuum your beds, furniture, and your room regularly.
  • Use a hand steamer to remove bed bug eggs in all cracks and crevices.
  • Make your home clutter-free. Clutter provides bed bugs a place to reproduce and increase.
