For us this means two things. Firstly stop using pesticides in your own gardens. It is pointless providing pollen rich plants if you also poison the bees along with aphids (and poisoned bees will return to their colonies thereby transmitting the poison). And secondly keep alert to the stellar EU effort to ban neonicotinoids from not just personal use (and bees do not respect 'private gardens') but crucially mass agricultural use. At the moment the UK and Germany are trying to block this ban (countries that are the base of Bayer and Syngenta). Sign every petition you can in support of banning neonicotinoids.
Here is one to pressure our MP's to ask Owen Paterson to support the proposed ban. The Buglife website gives example wording.
