Little Bug, Big Problems

Pests On Ficus
I've been treating a 12 ft ficus around a condo association with Dominion and Orthene and treated them 3 times more, once a month, with permethrin. Yet they still seem to be coming back. Is there a better chemical or process that will work.

Galls Are Just Swell
Just reading up on spruce gall. Everything I read states the best time to treat is in the spring. Would there be any benefit to treating it mid to late summer with either systemic or residual? Or, is the damage already done?

Fig Whitefly Remedies
Fig whitefly - where did it come from and what is the cheapest way to control it? Is there any home remedy such as liquid soap, garlic, or something natural, even if I spray monthly. I know about systemics, but they are very expensive.

Oak Caterpillars
I have found caterpillars in an Oak tree. They are about 1 1/2 to 2 inches long and are dark green with bright yellow stripes along the length of their bodies. The head is shiny black. Only the Oaks have them. Other trees right next have none. What are these the larvae of and how can I get rid of them? Thanks
