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.
