Cyonara 9.7 is labeled to control Japanese beetle adults only and should do a good job on those that contact a treated surface.
Cyonara 9.7 is not labeled for use on edibles such as tomato plants. We would not recommend consuming any fruits or vegetables that have been sprayed with this insecticide.
Cyonara 9.7 will not kill bedbug eggs, only the adults. It will continue to kill any adults that cross the treated surfaces once dry.
You want to give the Cyonara 9.7 ample time to dry before you water your lawn. After making your application we would suggest waiting 24 hours or so before watering. If you were to water sooner than that you would just be washing away the insecticide that you just applied.
Cyonara 9.7 and Demon WP are both great choices for perimeter pest control. The biggest difference is that Cyonara is a liquid concentrate that will dry clear, while the Demon WP may leave a visible residue on darker finishes.
Cyonara 9.7 can be applied at any time the temperature is above freezing as long as it is not raining or snowing.
