Root aphids

Hi . Greetings.    A few days ago noticed a growing number of ants crawling at the roots of my pumpkin plants. Today digging a little around the top of the roots, as suspected lots of white looking like aphids on the roots, loads of them. Im afraid im going to loose the entire patch. Any suggestions?
THANKS

eeeek sounds not good I have never come across them myself although they caused big problems in the past here in france with the vines ; Have you tried neem oil ?
Are there other varieties you could plant in the future that are less susceptible?
