 about 30 days, or you want to get 30 days out of them. If your fly trap fills up earlier than 30 days, then you probably need a larger one. So if you have the regular one, get the big bag if you're filling it up before 30 days. Yeah, just because you have a larger fly population. And then we also have reusable traps. Yeah. Okay. How far away? Is it 20 feet, 30 feet? Give me an idea.
