1. Mix the key ingredients
An effective homemade bug spray requires a carefully-selected mix of ingredients.
In a bowl or jug, or directly into your spray bottle, combine a cup of distilled water with one cup of witch hazel and a tablespoon of apple cider vinegar.
Karina Toner, operations manager at Spekless Cleaning, says, "Witch hazel is a natural astringent that helps to disperse essential oils, making it an excellent base for a bug spray that's both effective but gentle on skin."
Both Karina and property expert James Heartquist recommend Thayers Witch Hazel from Amazon. James says, "It’s a high-quality, natural astringent that helps the bug spray dry quickly on your skin without causing irritation. It’s also alcohol-free, which makes it gentle and suitable for all skin types."
The vinegar is highly effective against ants, spiders, and flies due to its strong smell and acidic nature. James recommends Bragg Organic Apple Cider Vinegar from Target. He says, "Known for its antibacterial properties and effectiveness in repelling insects, this comes from a trusted brand, so you know you’re getting a pure, organic product that’s safe to use in your homemade bug spray."
Other optional ingredients include a tablespoon of vodka — which can be particularly effective on soft-bodied insects such as aphids and mealybugs — and dish soap. John Target, of Target Pest Control, adds, "For extra potency, add a tablespoon of dish soap. The soap helps break down the bug’s exoskeleton."
For spray bottles, James recommends Sally's Organics Glass Spray Bottles from Amazon. He adds, "These are durable and prevent the essential oils from degrading. Glass bottles are also reusable and eco-friendly, making them a great choice for storing your homemade bug spray."
2. Add essential oils
Essential oils have an important dual function — not only do they contain natural compounds that are toxic or repellent to insects, they also smell great.
Add 10-20 drops of your preferred oils to the vinegar-water solution. Different oils provide different strengths, so combine them to suit your needs. For example, lemon eucalyptus, tea tree and citronella oil all make for strong mosquito or tick repellents, while peppermint and lavender oil can handle a variety of indoor pests including fleas, spiders and ants.
Karina says, "Personally, I'm a fan of combining eucalyptus and tea tree oil — not only do they provide a robust defense against bugs, they also have strong antibacterial properties."
This Spring Valley Pure Australian Tea Tree Oil from Walmart comes with great reviews and is good on your skin.
John adds, "For extra potency, you can also add 10 drops of neem oil, which has insecticidal properties."

3. Shake & spray
The last step is the easiest and most enjoyable. Simply shake your mixture vigorously in a spray bottle then get to work of repelling those unwanted intruders.
Apply the spray to areas where bugs are present or likely to enter. This can include door frames, window sills, and garden plants.
Avoid spraying directly on pets or near where children play. Some essential oils can be harmful if ingested or if they come into contact with sensitive skin. John says, "Keep pets away from the treated area for at least 30 minutes. Avoid using this spray on windy days to prevent it from drifting onto unintended areas."
Also, some plants may be sensitive to essential oils. Test on a small leaf before spraying extensively. John adds, "If you're using the spray in your garden, avoid spraying right before rain, as it can wash away the solution."
