1000 days in circulation means we'll have to wait at least 4 summers to start seeing a change, I'd wager. Also, it might depend on where there are different types of insects currently, and how successful they happen to be in reproduction and spreading over time.

Since neonics have a half-life of ~30 days when exposed to sunlight (unclear if that’s continuous exposure or what), it could be that we see some statistically significant improvements sooner than the 1000 days.

I think they hang around in the soil and waterways (where insects live) much, much longer than the UV exposed half-life.

Also, I’d imagine it will take ecosystems multiple seasons (so years) to rebound and reach equilibrium.
