The bottom line: this 16 oz concentrate is best for users who will mix it with water and often pair it with an adulticide, because its active ingredient, (S)-Hydroprene, stops immature insects from maturing and reproducing rather than killing adults immediately. It is a practical choice when the goal is sustained control of roaches, bed bugs, fruit and drain flies, and stored product pests.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eActive ingredient:\u003c\/strong\u003e Contains 9% (S)-Hydroprene which interferes with insect development and helps break breeding cycles.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTarget pests:\u003c\/strong\u003e Formulated to reduce populations of roaches, bed bugs, drain and fruit flies, and stored product pests when applied correctly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication methods:\u003c\/strong\u003e Mix the vial with one gallon of water and apply as crack-and-crevice, spot, or fogging treatments for flexible use in many locations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUse sites:\u003c\/strong\u003e Labeled for both food and non-food areas when directions are followed, allowing it to be used in kitchens and storage spaces with care.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Most effective when combined with a liquid insecticide, giving both immediate adult control and long-term suppression.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReapplication guidance:\u003c\/strong\u003e Provides clear interval recommendations such as every 4 months for roaches and every 2 weeks for bed bugs to maintain control.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis product suits pest management professionals, serious homeowners, and facility managers who understand mixing concentrates and integrating treatments.
