I've used Mavrik Aquaflow insecticide extensively on everything from bedding plants to 50' California live oak trees. Mavrik gives a high degree of control on every infestation I've tried it on. Even mites, whitefly and scales are controlled. Eugenia Psyllids are a huge problem in S. California. Mavrik gives an incredible six month control with one spray. The kill is very quick. The high dilution rates make it economical to use as well. I've been in the business nearly 40 years, and for me, Mavrik is the "go to" material.
