If you've got a particularly nasty infestation of 'bugs', you can easily get sprays (some labelled 'organic') which are suitable for edible crops - always read the label which will tell you which crops they can be used on since not all the sprays are suitable for every edible crop. As for the flies - well, it might not be the prettiest thing in the world, but I hang a good, old-fashioned fly paper in my greenhouse. The RHS believes that avoiding pests, diseases and weeds by good practice in cultivation methods, cultivar selection, garden hygiene and encouraging or introducing natural enemies, should be the first line of control. If chemical controls are used, they should be used only in a minimal and highly targeted manner. Because they fill the entire room with pesticides, these products are not to be used without prior knowledge of safe practices. The first thing you should do is make sure that all pets and children are kept well away from the area to be treated and not allowed to return until, at the very least, several hours after the product has dispersed. Also, make sure that you do not remain in the room after setting the bomb, whether or not you have skin and breathing protection since these are sometimes not enough to maintain your safety while using insect fog. Do I Need More Than One? Remove plants – a sheltered area with fleece protection is a suitable to hold plants while cleaning is carried out

Regarding sprays, there was a very interesting piece on CNN about supermarket fruit and veg stating that although all commercially sold fruit/veg is washed for 10 seconds before sale there was still traces of the farmers chemicals on them. Notice I said "on" not "in" but to my mind any growing plant will absorb chemicals sprayed on it. Glazing material should also be washed inside and out, but for plastic materials test on a small inconspicuous area first to be sure the cleaning material does not damage the glazing. Scrub off any old shade paint on the outside of the glass from the summer After the burning is over, it is impossible to enter the greenhouse for several hours. Dissipation of carbon dioxide should occur.
