- Active ingredient
- Nithiazine
- Chemical class
- The label names it 2H-1,3-thiazine, tetrahydro-2-(nitromethylene), carried in a yellow sugar-based bait matrix.[1]
- Mode of action
- Fly bait that kills through ingestion, as the label describes it; nithiazine is not listed in the IRAC classification[1]
- Signal word
- Starbar QuikStrike Fly Abatement Strip (Sandoz 9023 Fly Bait Station): Caution[1]
Made for the dumpster, the barn and the loading dock
Placement examples on the label include garbage chutes, waste containers, grease pits, outdoor restrooms, stables, dairy barns, milking parlors, kennels, aviaries, swine houses and areas around restaurants and groceries.[1]
The label says a single application kills flies for up to 8 weeks and attracts them within a 300-square-foot area. Ventilation doesn't reduce its effect because flies have to feed on it.[1]
Where it is used
Keep strips low, no higher than 4 feet. The label explains that flies feed near the ground, while flies seen higher up are mostly resting.[1]
Fix the strip firmly to a stationary surface with adhesive, since flies won't land on something swinging in the wind. Flat surfaces work best.[1]
At setup, squeeze the attractant ampoule until it snaps. Don't crush it, and expect a strong odor.[1]
Shield strips from moisture and direct sun where you can, and skip spots that get wet every day. Replace the strip when it stops working well.[1]

Common questions
- How many QuikStrike strips do I need?
- One per 300 square feet in enclosed spaces with light to moderate flies, or one per 100 to 150 square feet in open buildings or heavy infestations.[1]
- Which flies does it work on?
- The label says it is most effective against the house fly and the lesser house fly.[1]
- Why isn't my fly strip working?
- The label warns that strips hung above 4 feet, strips that move in the wind, and strips that stay wet all lose effectiveness. With light infestations, control may also be less obvious.[1]
