DIY Natural Ant Killer Spray
A simple, budget-friendly homemade ant spray made with everyday ingredients. This natural solution kills ants on contact, disrupts their scent trails, and helps keep them from coming back without harsh chemicals.
Servings: 1 16-ounce spray bottle
Cost: $2–$5
Equipment
- 16-ounce amber glass spray bottle
Ingredients
- 16 ounces tap water
- 1 teaspoon ground cayenne pepper
- 20 drops tea tree essential oil 100% pure
- 20 drops peppermint essential oil high quality, undiluted
Instructions
- Add tap water to your 16-ounce amber glass spray bottle, leaving about 1 inch of space at the top.
- Add the cayenne pepper, tea tree oil, and peppermint oil.
- Add a splash more water if needed to bring it close to full.
- Secure the sprayer and shake thoroughly to combine.
- Label your bottle and store it in a dark cupboard. Shake before each use since ingredients will settle.
Notes
Shake before every use. This mixture naturally separates.
If the spray stops working as well, it’s time to make a fresh batch.
Safe for most household surfaces, but test a small area first.
For best results, spray directly on ants and along their trails to break the scent path.
Use glass, not plastic. Essential oils can break down plastic over time.
Store in a cool, dark place to extend shelf life.
If you have pets (especially cats), double-check essential oil safety for your household.
