It is very important to take all necessary precautions to ensure that systemics are used correctly. This article will help you with systemic use: https://www.gardeningknowhow.com/plant-problems/pests/pesticides/systemic-pesticide-in-gardens.htm
Alternatively, you can use an organic systemic such as neem oil. This article will help: https://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm
