<DIV>What I would suggest is just spraying the tree down with water once or twice per week, could use a pressure washer, just on the undersides of the leaves. Customer could also use yellow sticky traps in their yard or a yellow kiddie pool with a drop or two of soap in it. Insecticidal soap would as a foliar spray if you applied it 2 or 3 x per week for 2 weeks. But you might not get any better control than using the water in bad aphid years.</DIV>

How do you spray a 70' tree repeatedly to <BR>remove aphids? Do oil sprays work in spring? Aphids are now gone, <BR>likely in bark I presume. Would imidacloprid be effective.
