Flesh Flies Control & Removal Guide

(Grey flesh flies, Carrion flies)

*Sarcophaga* spp. / Sarcophagidae

How They Get In

  1. Hallway and community garbage collection odors attract flies from outdoors.
  2. Indoor standing water and rotting debris allow self-breeding.
  3. Open doors and windows allow direct entry.
  4. Unsealed garbage continuously attracts flies to hover near doors and windows.

How to Get Rid of Them

  1. Pre-Treatment: Seal all garbage bags and close trash can lids. Remove rotting debris and kitchen waste. Wipe bathroom and balcony floors dry. Repair screen damage. Remove food and dishes.;
  2. Key Zones: Entry door and frame (protective band), windowsills and frames, around trash cans, bathroom corners, exterior side of hallway doors.;
  3. Application: Spray door/window frames in continuous bands. Exterior windowsills and balcony railings — priority for blocking before entry. Lightly spray indoor corners. Never on food.;
  4. Post-Treatment: Close doors/windows 30 minutes, ventilate. Physical protection is key: tight screens, door curtains, insect mesh on vents.;
  5. Prevention: Seal kitchen waste daily. Clean food residues promptly. Wash trash cans weekly. Inspect and repair screens regularly. Hang fly strips at doorways during summer.

Prevention & Follow-Up

Keep kitchen trash sealed tight and take it out every day to cut down on odors. Double-bag your trash and wash the can once a week to keep it clean. Install tight-fitting window screens and check them regularly for rips and holes. Hang fly strips near doorways or install a screen door to stop flies from getting inside. Wipe up food scraps right away—don't leave them sitting on counters overnight.
