I know it says not to apply if it's going to rain...but he product was dried way before it rained.
Normally as long as an insecticide like Talstar has had at least 6 hours of dry time after it has been applied, then it is considered rain fast to most rain conditions that would come afterwards. If you had a heavy down pour for a few days that started 7 hours after then you may need to reapply at that point. But standard summer rain showers should not break down the residual.
