Will this product work effectively to treat sand wasps/hornets emerging from a lawn (above a sandy septic leach field)? Is there a more effective product your could recommend?
Cynoff WP has been discontinued by the manufacturer. A product that is labeled to be used in your lawn for hornets and wasps is Bifen I/T. It can be broadcast across the lawn as well as used inside around the cracks and crevices as well.
