I have whiteflies and aphids in my hibiscus trees, they came indoors for the winter. How long will it take for this product to take affect and how long will this product last, will I need to purchase it again?
Bonide Systemic can take several weeks to translocate through trees. The exact amount of time depends on the species of tree, the size of the tree, how much water the tree is getting and of course the health of the tree. It is recommended that while you are waiting for the systemic product to translocate that you use a different product for an immediate kill of the pest insects such as Horticultural oil, Insecticidal soap or Talstar P. Systemic products last for 3-4 months in most cases.
