How to do it:
Use fine mesh screens on windows and doors.
Seal cracks and gaps in walls and around entry points.
Store food in airtight containers.
Dispose of garbage regularly and keep bins sealed.
Clean up spills and food waste immediately.
Hang fly traps or sticky strips near entry points.

Result:
These steps reduce the chances of blow flies entering and contaminating your goods.

Problem:
If screens are damaged, containers are not fully sealed, or cleaning is inconsistent, blow flies may still access and damage your goods.

How to do it:
Create a mixture of equal parts vinegar and water in a spray bottle. Add a few drops of essential oils like eucalyptus or lavender. Spray this solution around areas where goods are stored. Keep goods covered with fine mesh or cloth to prevent blow fly access.

Result:
This natural spray repels blow flies and the physical barrier prevents them from reaching your goods.

Problem:
If the spray is not reapplied regularly or the covering is not secure, blow flies may still access and damage your goods.

How to do it:
Physically remove blow flies and block their entry points to protect your goods.

Result:

• Regularly inspect storage areas for blow flies.
• Use fly swatters or vacuums to remove visible flies.
• Seal windows, doors, and cracks with screens or caulk.
• Install door sweeps and keep doors closed.
• Dispose of waste promptly to reduce attraction.

Problem:
This method may fail if all entry points are not sealed or if flies breed in hidden areas, making complete exclusion difficult.

How to do it:
Use predatory insects like parasitoid wasps to control blow fly populations around your home.

Result:

• Place wasp pupae near entry points and garbage areas.
• Wasps will parasitize blow fly larvae, reducing their numbers.
• Fewer adult blow flies will enter your house and damage food.

Problem:
This method may fail if wasps do not establish well, or if blow fly populations are too high for the wasps to control effectively.

How to do it:
Mix 1 part household ammonia with 3 parts water. Pour into a spray bottle. Spray affected areas and surfaces where blow flies are present. Repeat every 2-3 days. Dispose of any infested goods and keep storage areas clean.

Result:
Reduces blow fly presence and prevents further infestation by deterring egg-laying.

Problem:
Method may fail if eggs or larvae are hidden in inaccessible areas, or if cleaning is insufficient, allowing reinfestation.
