I have heard of this, but am seeing it now on my young cucumber plants. How
devastatingly spectacular--big ants seemingly patrolling the vines up and
down while the sheltered aphids grow and thrive, literally sucking the life
out of my baby cucumbers.

I am currently on the lookout for a praying mantis to set out there, but in
the meantime, what can I do to stop this?
