We do use the Cutter yard spray early in the morning (before many of the beneficials are out and about) but there are areas where DH is not allowed to spray. If we don't get lots of rain, that can last for a month or so. We also put the mosquito dunks in our gutters in case there's any standing water there and in bird baths. Don't have any buckets or cans that sit out. Have a fountain that's always running. You can make a spray out of the mosquito dunks for spraying wet or damp pastures as well.
