DIY Insecticidal Soap: Homemade Pest Control Recipes

You can fight soft-bodied pests (aphids, mites) with stuff under your kitchen sink.

Recipe 1: The Basic Soap Spray

Kills on contact. Good for Aphids and Spider Mites.

• 1 Quart Water (Warm)
• 1 Teaspoon Mild Liquid Dish Soap (Castile soap is best; avoid “Degreasers” or heavy detergents)
• Mix: Shake gently. Spray directly on pests.

Recipe 2: The Alcohol Wipe

Good for Scale and Mealybugs.

• 1 Cup Rubbing Alcohol (70% Isopropyl)
• 1 Quart Water
• Action: Dip a cloth or spray. Test on a single leaf first to check for sensitivity.

Recipe 3: The “Spicy” Repellent

Deters pests from coming back.

• 1 Quart Water
• 1 Teaspoon Cayenne Pepper
• 1 Drop Dish Soap (to help it stick)
• Warning: Do not touch your eyes after using this!

Important Safety Note

Always test patch. Spray one leaf and wait 24 hours. If it doesn’t burn, treat the whole plant. Never spray in direct sunlight.
