Dark Rice Field Mosquito
Psorophora columbiae
The Dark Rice Field Mosquito breeds prolifically in rice fields and other flood-irrigated agricultural areas across the southern United States. Post-irrigation emergences can produce staggering numbers of aggressive biters that make outdoor activity unbearable in rural communities.

Size
5-7 mm
Color
Dark brown to black with scattered pale scales
Key Trait
Associated with rice-growing regions and flood-irrigated agriculture; breeds in massive numbers in rice fields.
Behavior & Habitat
Aggressive biter active day and night during peak emergence. Breeds in temporary flood waters, especially rice fields. Adults are strong fliers and can migrate considerable distances from agricultural areas.
Habitat: Rice fields, flood-irrigated cropland, and temporary pools in agricultural regions of the southern US.

Signs of Infestation
- Overwhelming mosquito numbers near rice-growing areas after irrigation
- Aggressive biting day and night during peak emergence
Risks & Damage
Not a major disease vector but causes extreme nuisance; bites can trigger allergic reactions.
Prevention Tips
- 1.Coordinate with local mosquito abatement districts in agricultural areas
- 2.Use personal protective measures during peak emergence
- 3.Maintain screened enclosures for outdoor living in affected areas
Why DIY Treatment Often Falls Short
Breeding occurs across thousands of acres of agricultural land, far beyond any homeowner's ability to treat.
Professional Treatment
Control is primarily a public health and agricultural coordination effort. Residential barrier sprays can provide temporary relief during peak emergence. Some rice-growing regions have active abatement programs.
