Step-by-Step Guide to Make Your Homemade Bed Bug Spray

Choose Your Essential Oils
Essential oils are powerful, natural repellents that can help deter and kill bed bugs. Some oils, such as tea tree oil, peppermint oil, and lavender oil, are particularly effective due to their strong aromas and insecticidal properties. When selecting your essential oils, consider combining them for an added punch. For instance, tea tree oil is well-known for its antibacterial properties, while peppermint oil has a strong, refreshing scent that repels pests. Use around 20 drops of your selected oil per spray bottle to ensure it has a potent enough fragrance to ward off bed bugs.
Prepare the Spray Solution
To create your bed bug spray, you'll need a spray bottle, water, rubbing alcohol, and essential oils. Fill the spray bottle with water, leaving a small amount of space at the top for the other ingredients. For a standard 16-ounce spray bottle, add approximately 1 tablespoon of rubbing alcohol. The alcohol helps to kill the bugs on contact and acts as a solvent to blend the oils and water more effectively. Add the 20 drops of essential oil into the bottle. If you're using tea tree oil, you can enhance its effectiveness by adding a few drops of lavender oil, which is also known to help combat bed bugs while offering a pleasant scent.
Shake Well
After adding all the ingredients to the bottle, securely screw the cap on and shake it well. Shaking the bottle ensures that the water, rubbing alcohol, and essential oils are thoroughly mixed. This is crucial, as it ensures that the solution maintains its pest-repellent properties and that the oils are evenly distributed throughout the spray. It also helps to break down any particles that might otherwise separate, ensuring an effective spray every time.
Apply the Spray
With your homemade bed bug spray ready, it's time to apply it to the areas where bed bugs are most likely to hide. Focus on spraying around your bed, mattress seams, and the bed frame, paying close attention to cracks and crevices—these are common hiding spots for bed bugs. Be thorough and ensure that all potential entry points, like cracks in the walls, furniture, or flooring near the bed, are well-sprayed. You may also want to treat any upholstered furniture or curtains in the bedroom, as these are also popular hiding spots.
Allow to Dry
After applying the spray, give it time to dry and work its magic. Allow the solution to sit on the surfaces for several hours to kill any bed bugs or eggs it comes into contact with. The alcohol helps to dehydrate and kill the bugs quickly, while the essential oils create an inhospitable environment for any remaining bugs. It’s important to repeat this process daily until all signs of bed bugs are gone, as consistency will ensure thorough elimination and prevent re-infestation.
Additional Homemade Bed Bug Remedies
In addition to homemade bed bug sprays, there are other natural remedies that can help you get rid of bed bugs:
1. Baking Soda

Baking soda is an effective, natural insecticide that can help control bed bug infestations. It works by absorbing moisture and drying out bed bugs, ultimately leading to their demise. To use baking soda, sprinkle a generous amount around areas where you suspect bed bugs are hiding, such as your mattress, bed frame, or cracks in the floorboards. Leave the baking soda in place for several days to allow it time to dehydrate the insects. Afterward, vacuum it up thoroughly. It’s a non-toxic, eco-friendly method that can be used safely around pets and children.
2. Diatomaceous Earth

Diatomaceous earth (DE) is a fine, powdery substance made from the fossilized remains of tiny aquatic organisms known as diatoms. When bed bugs come into contact with DE, it punctures their exoskeletons and dehydrates them, ultimately killing them. DE is safe for humans and pets but should be used with caution in areas where it may be inhaled. Lightly dust the powder around your bed frame, mattress seams, baseboards, and other places where bed bugs may hide. Leave it for a few days, then vacuum up the residue. DE is an effective, long-lasting solution for bed bug control.
3. Rubbing Alcohol

Rubbing alcohol, specifically isopropyl alcohol, is a powerful and fast-acting tool in killing bed bugs. It works by dehydrating the insects and disrupting their cell membranes. To use rubbing alcohol as a bed bug treatment, pour it into a spray bottle and spray directly on bed bugs to kill them instantly. For broader coverage, you can dilute rubbing alcohol with water in a 1:1 ratio and spray it on areas where you suspect bed bugs are hiding. While effective, be mindful of its flammability—keep it away from open flames, heat sources, or sparks, and ventilate the area well when using.
4. Tea Tree Oil

Tea tree oil is a natural essential oil known for its strong scent, which is a potent repellent for bed bugs. In addition to repelling pests, tea tree oil also has antibacterial, antifungal, and antiseptic properties, making it a multi-purpose remedy. To use, mix several drops of tea tree oil with water in a spray bottle, and apply it directly to the affected areas, such as your mattress, bed frame, and baseboards. Repeat the application daily, especially in areas where you’ve noticed an infestation. Over time, this treatment will help keep bed bugs at bay, though it may take a few weeks to fully see results.
5. Vacuum Cleaner

Using a vacuum cleaner is a crucial step in the battle against bed bugs. A vacuum helps to physically remove bed bugs, their eggs, and larvae from your mattress, furniture, carpets, and floors. Focus on vacuuming seams, crevices, and folds in your mattress and upholstered furniture, as well as any cracks and crevices in the floors or walls where bed bugs may be hiding. After vacuuming, immediately seal the vacuum bag in a plastic bag and dispose of it outside of your home to prevent any bugs from escaping. Vacuuming is an ongoing part of an integrated pest control plan, alongside other methods.
6. Dryer Sheets

While dryer sheets won’t kill bed bugs, they are often used as a deterrent. The scent of dryer sheets is unpleasant to bed bugs, which can help discourage them from approaching or hiding in areas where the sheets are placed. To use, simply place dryer sheets under your mattress, between the folds of your bed frame, or around your furniture. The sheets create a barrier with their strong fragrance, which bed bugs tend to avoid. While this method won’t eradicate an infestation, it can help reduce the chances of bed bugs taking up residence in your bedding or nearby areas.

Preventing Future Bed Bug Infestations

While homemade bed bug sprays are effective at eliminating bed bugs, prevention is key to avoiding future infestations. Here are some additional tips to help keep bed bugs at bay:
1. Regularly Wash Bedding
It's essential to wash your bed sheets, pillowcases, blankets, and any other bedding materials regularly, ideally every week or two, in hot water (at least 120°F). The heat helps to eliminate any bed bugs or eggs that may have hitchhiked onto your bedding. Make sure to dry the bedding on the highest heat setting for at least 30 minutes to kill any remaining bugs or eggs. Washing regularly not only helps with bed bug prevention but also ensures that your bedding stays fresh and clean.
2. Inspect Secondhand Furniture
When bringing in secondhand furniture, whether from a thrift store, garage sale, or a friend's house, take the time to thoroughly inspect it for any signs of bed bugs. Pay close attention to seams, cracks, and crevices where bed bugs might hide. Look for small, dark spots which could be blood stains or excrement, and check for live bugs, which are usually visible to the naked eye. If you notice any signs of bed bugs, it’s best to avoid bringing the furniture into your home or take appropriate steps to treat it before use.
3. Use Mattress Encasements
A mattress encasement is a specially designed zippered cover that fits over your mattress and helps to prevent bed bugs from hiding in the seams. Not only does it block new bed bugs from infesting your mattress, but it also traps any existing bed bugs inside, effectively suffocating them. Mattress encasements are a useful preventive measure and can be an important part of your bed bug defense strategy. Choose an encasement made of durable, bed bug-proof fabric, and ensure it fits snugly around the mattress.
4. Vacuum Frequently
Vacuuming regularly is one of the most effective ways to remove bed bugs, eggs, and larvae that may be hiding in carpets, upholstery, and other surfaces. Focus on areas where bed bugs are most likely to hide, such as along baseboards, under furniture, and around cracks and crevices. Be sure to empty the vacuum bag or canister immediately into a sealed plastic bag and dispose of it outside of your home to prevent any bed bugs from escaping and re-infesting your space. Frequent vacuuming can significantly reduce the chances of a bed bug infestation.
5. Seal Cracks and Crevices
Inspect your home carefully for any cracks or crevices, particularly around baseboards, window frames, doorways, and electrical outlets. These small spaces can provide perfect hiding spots for bed bugs to thrive. Seal any gaps with caulk or other appropriate sealants to prevent bed bugs from entering your home or finding refuge in these hidden spaces. By reducing potential entry points, you are helping to create a more secure environment and reduce the risk of an infestation.
