With the anticipated explosion of Zika Virus disease in our un-immunized (by prior infection; there is no vaccine) US population, control of Aedes aegypti and Aedes albopictus mosquitoes, the vectors for Zika virus, is paramount. These mosquitoes use both natural and artificial water-holding containers for hatching larvae (more often small containers). I will list options as comprehensively as possible.

Mosquito Larva Control

1. Water-holding containers that cannot be dumped, covered, or discarded should be treated with long-lasting larvicide,

  • Chemical: temephos
  • Biological: Bacillus thruingiensis var. israelensis, Spinosad, Methoprene (granules or briquets), pyriproxyfen, Diflubenzuron, Navaluron
  • Monomolecular films and oils

2. Eliminate larval habitats within 100-200 yards around a home.

3. Breeding sites: cavities in fence poles, trees, bricks

Uneven floors and roofs

Clogged gutters

Air-Conditioner trays


Storm drains

Water meters

Public wells

Septic tanks

Bird baths (change water each week)

Flower pots (store upside down)

Fire pits (drain them)

Children’s wading pools

City storm drains (near your home)


Children’s toys

Adult Mosquito Control


  1. Mosquito misting systems (pyrethrin)
  2. Air curtains (outdoors)
  3. Portable traps (Mosquito Magnet trap)
  4. ThermaCell Mosquito Repellent Patio Lantern
  5. Insecticide spraying of plants/ outdoor surfaces (effective 4-6 weeks)- pest control companies
  6. Assure tight-fitting screens, doors
  7. Air-Conditioning
  8. Repair/ correct low-lying water-pooling areas (ditches, ground ruts)

Bug Bite Prevention

  1. Wear long sleeves, long pants, socks
  2. Avoid tight clothes
  3. Darkly-colored clothes
  4. Avoid perfume and after-shave
  5. treat (or purchase) clothing or permethrin
  6. Insect repellents on exposed skin: DEET (> 30%), incaridin (> 20%); lemon eucalyptus extract (> 30%)
  7. DEET/ picardin OK with pregnancy
  8. Mosquito bed-netting (treated with permethrin)
