Today I noticed that my very neglected greenhouse-grown sweetcorn are
covered with spider mite (the leaves are covered, that is). I've put the
plants outside, as I assume that the outdoor cold will kill off the
mites -
is that right?

Make a water based spray using peppermint, cloves and garlic. . It shifts
them very quickly without using chemicals. you need to use it every four
days for 5 or 6 applications as that is the egg hatching cycle.
