- Find and eliminate the breeding source — garbage, drains, manure, or rotting produce. This matters more than any spray.
- Set out fly bait away from food prep areas.
- Apply a residual spray to the surfaces flies rest on, like walls, ceilings near light fixtures, and eaves.
- Add fly lights or traps near doors and other entry points to catch stragglers.
- Repair screens and seal gaps to keep new flies from getting in.
- Reapply per the label — once the breeding source is gone, most infestations don't come back.
Wear long pants, a long-sleeved shirt, closed-toe shoes with socks, chemical-resistant gloves, and goggles. Add a respirator if the label calls for it or ventilation is poor.
