apparently the site I'm on now has probs with the above (and carrot fly!) - anyone got any tips on how to deter or get rid of it, preferably without any chemicals ...
www.savetheplot.co.uk - still updating this on details of my previous plot, which one day we hope to return to lottie use, god willing;)
Just the usual - fleece!! Or mesh if you can afford it.
Alternatively, close-woven (ie non-patterned) net curtains. Jumble sales are good places to look, as are charity shops.
