We care about the environment, so we use as little chemicals as possible. Where possible I use biological control, for instance phytoseiulus persimilis against spint.
And you may very well get green filling material with your order. These green ‘bits’ look like polystyrene chips, but are actually made of maize and when thrown into water dissolve into a harmless starch solution. You can also throw them on your compost heap. They are coloured green to differentiate them from the non-biodegradable polystyrene ones. Should you still get white ones (sometimes mixed with non-degradable green ones) with your order from my shop, you can be sure that they are second-hand chips that a local shop saves for me. Better to reuse than to throw away! Don’t ask me why they have green non-degradable ones as well as using that colour for the degradable ones – how to confuse the well-meaning environmentally conscious person – but the easiest test is to throw one in water and see what happens. If nothing happens, they are the non-degradable ones.
