Marseille Soap Solution Create a potent mixture by dissolving a few shavings of Marseille soap in half a liter of non-calcareous water. Enhance the effectiveness by adding a tablespoon of black soap and two tablespoons of 70% isopropyl alcohol. Apply this solution directly to the mealybugs with a brush to disrupt their protective coating and eradicate them.
Water Washing A gentle yet effective method involves washing plants with a strong jet of water, which can dislodge mealybugs from their hiding spots. This method is particularly useful for mild infestations and can be repeated as necessary.
Homemade Insecticide Spray To prepare this spray, blend one bulb of garlic, one small onion, and one teaspoon of cayenne pepper into a paste. Mix this paste with one liter of water and let it infuse for an hour. After straining through cheesecloth, add a tablespoon of liquid dish soap to the solution. This homemade pesticide can be stored in the refrigerator for up to a week and sprayed directly on infested areas.
