The pesticide was banned by the EU 2 years back. Is there any evidence bees numbers have resurged? I'd be happy to keep this banned, I'm just asking...

  From the link below, at least the effect on bumble bees is clear cut: The impact of neonicotinoids on bumble bees is more in agreement. The majority of lab, semi field, and field studies report negative implications of neonicotinoids. Of four field studies investigating bumble bees [23-26], three report such effects [23, 25, 26]. These bees are about 2-3 times more sensitive than honey bees to neonicotinoid toxicity [13, 27, 28].

    But the question here was different: did the ban produce any measurable effect in the two years since it has been established? For example, we may have replaced neonicotinoids with massive use of something else, causing even worse problems. My guess would be that we just don't have the data, but it's an interesting question.

  It is not the only factor impacting the bees and the impact is not even quantified, so it is very hard to measure the results in uncontrolled environment (in nature). I think the bee populations are still in danger, ban or not.
