Got a really bad infestation on the leeks in my greenhouse. In fact too many to remove by hand. I guess I can't use an insecticide like the Woolworths Bug Gun my wife has for the roses. Any ideas please? They're starting to look sick.

The Woollies insecticide contains pyrethrins.

I would use a spray specifically for edible crops.

I'd get those leeks outside to harden off, if I were you, Scribbler.

my dada used to use washing up liquid and water in a sprato get aphids off seemed to work too!

Put some soapy water in the spray mister thingy, adjusted the nozzle so it was jet rather than a spray, and blasted the little b*ggers off. Leeks now hardening off and seem to be recovering.
