Fly Problems: Four Source-First Checks
A short visual guide to drain-film inspection, sanitation and exclusion, possible blow-fly sources, and seasonal cluster-fly entry points.
Read the video transcript
Start by identifying the fly and locating where immature stages could develop. For drain flies, inspect the organic film inside drains and other persistently wet areas. For house flies, correct waste, sanitation, screen, and door conditions. A sudden appearance of metallic blow flies can justify checking for a hidden organic source, but does not identify that source by itself. In regions with seasonal cluster flies, seal upper-wall entry gaps before adults move into buildings for winter shelter. Treatment should follow confirmed species and source evidence.

The sighting pattern should determine the inspection route
A location name cannot identify the fly or its breeding source. Around San Francisco, California, record size, color, resting behavior, where adults collect, and when they appear. Then inspect the matching source category instead of treating every small fly or every large fly the same way.
Small flies near drains or wet areas
UC IPM explains that moth or drain flies develop in moist organic matter, often the film inside sink, shower, or sewer drains. Large numbers can point to a source larger than one drain. Confirm the site and remove the developmental material; spraying adults does not remove it.

EPA identifies removal of animal waste, garbage, decaying plant material, and moist larval habitat as the main IPM opportunity. Screens and increased air movement can help with entry; traps are supplements, not substitutes for source correction.
EPA fly IPM strategiesWarm-weather development check
Warm conditions can shorten development for some nuisance flies, but weather alone does not identify the species. UC IPM recommends eliminating larval habitat and adult attractants, using screens and doors for exclusion, and treating chemicals as a limited tool rather than a substitute for sanitation and source removal.
