Problems with spider mites? Give your plants a bath with insecticidal soap! Made from a simple soap solution, insecticidal soap is a greener, more eco-friendly approach to insect problems in the garden and on houseplants. You can buy insecticidal soap in a ready-to-use spray or make your own using this simple recipe.
Insects Affected by Insecticidal Soap
Insecticidal soaps work by disrupting the cell membranes and dissolving the natural waxy coatings found on soft-bodied insects including:
Aphids
Immature leafhoppers
Mealy bugs
Scales
Spider mites
Thrips
Immature white flies
Eggs and pupae of other insects
Eco-Friendly Advantages of Insecticidal Soap
If made and used correctly, insecticidal soap is more eco-friendly than traditional insecticides since it:
Has no residual effect.
Only works when coming in direct contact with soft-bodied insects.
Is biodegradable and nontoxic (if the right soap is used).
Kills target insects without harming birds or hard-bodied beneficial insects such as predatory wasps, lacewings, and pollinating bees. |
