The Problem

Riverside's semi-arid climate โ€” with humidity averaging 53% and annual rainfall around 11 inches โ€” creates conditions where flies can breed and spread efficiently.The city's reputation as Mission Inn, UC Riverside means a steady flow of people and goods, which can contribute to pest movement and introduction.The urban nature of Riverside, combined with older housing stock and seasonal weather patterns, means flies can become a problem quickly.flies taste with their feet and can only consume liquids.

Warning Signs

  • โ€ขIncreased pest sightings during spring through fall; cluster flies overwinter indoors.
  • โ€ขNests, webs, burrows, or mounds on or near the property.
  • โ€ขGrease marks or track lines along baseboards and walls.
  • โ€ขDamaged plants, lawn areas, or garden vegetation.
  • โ€ขVisible flies or evidence of their presence (droppings, shed skins, nests).
  • โ€ขUnusual odors โ€” many pests produce distinctive smells when infestations are established.

Risks of Waiting

  • โš Psychological stress and anxiety from living with an active pest problem.
  • โš Risk of infestation spreading to neighboring properties in multi-unit buildings.
  • โš Business reputation damage if customers or tenants encounter pests.

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.

DIY vs Professional

The sighting pattern should determine the inspection route

A location name cannot identify the fly or its breeding source. Around Riverside, 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.

House flies around doors, waste, or food

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 strategies

Warm-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.
