4 Easy DIY Sprays Using Kitchen-Safe Ingredients
Pests in the home are more than a nuisance—they can pose real health threats. From disease-carrying mosquitoes to allergen-spreading cockroaches, eliminating these invaders should be a priority. Fortunately, there are natural, non-toxic solutions that can be easily prepared with ingredients found in your kitchen. Below, we present four powerful DIY insect sprays that are safe, cost-effective, and highly effective.
Natural Ant Spray – Eliminate Trails & Nests with Ease
Ingredients:
- 1 cup water
- 1 cup white vinegar
- 1 teaspoon cinnamon powder
Preparation & Use:
Mix water and vinegar in a spray bottle. Add cinnamon powder and shake vigorously to combine. This blend targets ants’ scent trails and disrupts their colony communication.
Application Tips:
- Spray liberally along baseboards, countertops, and pantry corners.
- Focus on entry points, such as windowsills, doors, and cracks.
- Reapply every 2–3 days for persistent ant activity.
Why It Works:
Vinegar alters ants’ pheromone trails, while cinnamon acts as a powerful repellent with a strong scent barrier.
DIY Cockroach Spray – Destroy Roaches Naturally
Ingredients:
- 1 cup vinegar
- 1 teaspoon borax
- 5 drops clove oil (or 1 tsp clove powder)
Preparation & Use:
Combine the vinegar and borax, then add clove oil or powder. Shake well before use. This formula is lethal to cockroaches and can help control infestations.
Application Tips:
- Spray in dark, damp areas where roaches hide, including under sinks, behind fridges, and inside cabinets.
- Apply directly into cracks, crevices, and drain holes.
- Reapply weekly or after cleaning the sprayed surfaces.
Why It Works:
Borax acts as a slow poison that disrupts digestive systems, while clove oil is a potent natural insecticide with long-lasting effects.
Bed Bug Spray – Safe for Mattresses and Bedrooms
Ingredients:
- 1 cup water
- 1 tablespoon diatomaceous earth (food grade only)
Preparation & Use:
Add diatomaceous earth to the water in a spray bottle. Shake thoroughly before each use to ensure even distribution.
Application Tips:
- Lightly mist on mattress seams, bed frames, baseboards, and under furniture.
- Use cautiously—avoid inhaling the dust during spraying.
- Let the surfaces dry and avoid vacuuming for a few days.
Why It Works:
Diatomaceous earth punctures the exoskeletons of bed bugs, dehydrating them to death without the use of harsh chemicals.
Mosquito Spray – Repel & Deter Flying Pests Naturally
Ingredients:
- 1 cup water
- 10 drops lemongrass oil
- 10 drops citronella oil
Preparation & Use:
Add both essential oils to the water and shake vigorously. This spray creates an aromatic barrier that mosquitoes detest.
Application Tips:
- Spray around window frames, doorways, and outdoor lights.
- Apply to curtains, screens, and porch areas before evening.
- Reapply daily during peak mosquito activity.
Why It Works:
Citronella and lemongrass oils are proven natural repellents that mask human scent, driving mosquitoes away effectively.

Natural remedies require consistency. Use daily or weekly applications depending on infestation severity.
