Mosquitoes: Prevention and Control Guide

About Mosquitoes

Mosquitoes are responsible for more human deaths worldwide than any other animal, transmitting diseases including West Nile virus, Zika virus, dengue fever, malaria, Eastern equine encephalitis, and heartworm in pets. In the United States, West Nile is the most common mosquito-transmitted disease, though regional risks vary significantly.

Only female mosquitoes bite — they need blood proteins to produce eggs. Males feed only on plant nectar. A single female can lay 100-200 eggs per batch and complete multiple batches per season, which is why populations can explode rapidly.

Identification

Culex pipiens (common house mosquito): gray-brown, cross-banded abdomen. The primary West Nile vector. Breeds in stagnant water including bird baths, gutters, and drainage ditches.

Aedes albopictus (Asian tiger mosquito): distinctive black and white striped pattern. Active during the day, unlike most mosquitoes. Breeds in very small containers. Vector for dengue and Zika.

Aedes aegypti (yellow fever mosquito): dark with white lyre-shaped markings on thorax. Found in Gulf Coast states and southern California. Primary dengue and Zika vector.

Anopheles species: dark spotted wings, resting at a characteristic angle. Primary malaria vectors (malaria is very rare in the US but still present in some areas).

Signs of mosquito activity:

  • Bites, especially during dawn and dusk for most species
  • High-pitched whining near ears (wing vibration)
  • Resting adults on shaded vegetation, under decks, or on walls

Prevention Tips: Source Reduction Is Key

The most effective mosquito control eliminates breeding water before larvae develop:

  1. Eliminate standing water — Empty, remove, or cover anything that holds water. Check weekly after rain: flowerpot saucers, tarps, buckets, tire swings, and play equipment
  2. Maintain gutters — Clean gutters quarterly. Clogged gutters hold water for weeks and produce thousands of mosquitoes
  3. Change birdbath water — Every 2-3 days. Mosquitoes complete their aquatic life stage in 4-7 days
  4. Fix yard drainage — Regrade low spots that pond water after rain
  5. Treat permanent water features — Use Bti mosquito dunks in ponds, ornamental water features, and rain barrels. Bti kills mosquito larvae but is safe for fish, frogs, and other wildlife
  6. Maintain your lawn — Adult mosquitoes rest in tall grass and dense vegetation during the day. Mow regularly

Treatment Options

Biological control: Bti (Bacillus thuringiensis israelensis) — the gold standard for larval control. Available as dunks (long-lasting) or bits (faster-acting). Use in any standing water that can’t be eliminated.

Repellents: DEET (20-30%), picaridin (20%), or oil of lemon eucalyptus (30%) for personal protection. Apply to exposed skin and clothing.

Yard treatments: Pyrethroid barrier sprays applied to vegetation reduce adult populations around entertainment areas. Effective but temporary — reapply weekly or after rain.

Professional services: For severe yard infestations, professional mosquito control services apply targeted treatments to resting sites and larval habitats.

When to Call a Professional

Consider professional treatment if:

  • Mosquito populations are preventing outdoor use of your yard
  • You have breeding sites you can’t eliminate (retention ponds, ditches, wetlands)
  • A mosquito-transmitted disease outbreak has been reported in your area
