I already have this and use it, I just want to know how often I should be applying it, currently I apply it every month. There are just so many bugs here in NC
Talstar has a residual for up to a month outdoors and 90 days indoors. Normally as long as 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.
