Potatoes attacked

I have had my entire winter new potatoes crop destroyed by aphids (I’m assuming they are called aphids)   All my Pentland javelins and Roosters were growing great they were all at least 2 foot high, when these tiny white flies attacked them. I have been spraying with bug clear (which stinks the tunnel) but to no avail, there are some on my chillies, cucumbers and DFB’s but don’t seem to have been affected the cucumbers at the end of its life so I’ll be pulling them up. 
Any suggestions for what to do in the tunnel ?
What about composting the damaged plants can I ?
