Simplest cheap one is probably as good as any. The fat based soft soaps
are supposed to be better at gungin up insect breathing holes.
You could spray thin cooking oil, that would impede their respiration.

Many of the 'green' insecticides available are little more than that,
except that they emulsify the oil to give a thick white gloop that you
dilute. I'm sure if you took a couple of tablespoons of cooking oil of
your choice, added a few drops of soap of your choice and whizzed the
mix well in a pint of water in a liquidiser, you'd get the same thing
for a fraction of the cost. That's assuming it didn't just fill the
kitchen with froth!

Might as well just use a cheap shampoo if that's all they are
