Safe way to spray

Wait for settled weather with little wind and no rain.
Dress yourself well, wear long sleeves and rubber gloves, follow packet direction carefully.
If you suffer from allergies, wear a dust mask when handling any powdery substance.
Only make up the amount you will use in one application. Into the sprayer put the correct amount of concentrate. Fill slowly with water. Add 5 drops of washing-up liquid to act as a wetting or sticking agent.
Spray in the early morning or late afternoon to avoid burning the leaves and to reduce the impact on non-target insects.
