systemics with orchid pests

[tuvoc]

Hi birkie. A systemic insecticide works by entering the plant, and killing the critters that eat the tissue containing the poison, so the plant has to be eaten before the stuff works. A better idea would be to get rid of them before they get to your plants. There are several baits that you can spread around the area that will get rid of them before they get to your plants.
