Green aphids on apple trees...spray with soap?

sam_ny(5)August 25, 2013

Hello all,
Just noticed what look like green apple aphids on the terminal buds of ALL my young apple trees (being tended by black ants). I thought I'd do a dish soap/water spray, as I've seen recommended here and other places. I've seen conflicting advice on where to spray, however. One link said spray the trunk and branches and avoid the leaves, while a few others said I have to wet the pests directly (which would imply spraying the leaves and buds). Any thoughts? Anything else I should know? Thanks for any advice!

Try a harsh water spray first. Repeat in several days to get the progeny of those you missed.

Thanks Jean. I've read about doing that, but most of the trees are too far to reach with a hose.

Then use insecticidal soap.
