Fogging for Flies: What It Does and Does Not Do

Fogging is often offered as a quick fix for flies. It has its place, but also limits.

The short answer

Fogging disperses a fine mist that knocks down flying adults in the treated space, giving short-term relief. It does not remove breeding sources, eggs or larvae, and flies return if waste and drains are not managed. Fogging needs preparation, re-entry time and food protection. Use professionals, particularly in food areas, and combine with sanitation and proofing.

What it does

• Reduces adult flies quickly.
• Useful for outbreaks and events.

What it does not do

• Remove breeding sites.
• Stop new flies entering.
• Replace sanitation.

Safety

1. Remove or cover food and utensils.
2. Keep people and pets out during and after as advised.
3. Ventilate before re-entry.
4. Wipe food surfaces afterwards.

When to call a professional

Fogging should be done by trained professionals using appropriate products.
