Blow Fly and Bottle Fly Identification and Property Tips

A sudden group of metallic-looking flies indoors can warrant a search for the source. Identification helps distinguish bottle flies from other household flies.

Identification and habits

Many familiar blow flies have shiny green or blue bodies. Larvae can develop in decaying animal material, and hidden sources can produce a sudden appearance of adults. This does not establish a particular source without inspection.

What to do at your property

Check accessible waste areas and note where flies gather. Report persistent activity or a suspected inaccessible source. Avoid opening walls yourself; discuss source removal and prevention rather than relying only on killing visible adults.

Photograph the pest clearly and note where and when it appeared. Ask Plank about identification and whether inspection, prevention or selected treatment is appropriate. The service scope and any follow-up are confirmed for your property.
