Mosquito facts
A single female may lay 100 to 300 eggs at a time and may average 1,000 to 3,000 offspring during her life span.
A mosquito develops from egg to adulthood in four to seven days.
Most mosquitoes remain within a one-mile radius of their breeding site.
Mosquitoes do not feed on blood. The female requires a blood meal for development of her eggs, but most adults feed on flower nectar, juices, and decaying matter for energy.
The average life span of a female mosquito is three to 100 days. Males live 10 to 20 days. |

The mosquitoes in Sunriver can be bad in any given year. Is anything done about these biting, buzzing insects? YES! Each year the Sunriver Owners Association contracts with Four Rivers Vector Control District, which comes through Sunriver almost daily with fog trucks, helicopter, boat and on foot to spray and/or apply larvacide to kill young and adult-flying mosquitoes. There is also spraying done in adjacent communities and Forest Service lands to help try and lessen the mosquito population in and around Sunriver.
Fog spraying is usually done in the evenings between 9 pm and midnight when temperatures remain above 55 degrees. Fogging runs typically include the entire north end of Sunriver to get insects coming from the marshy areas around Benham Falls and around Sunriver's core to the Deschutes River to intersect insects that come from that area.
Unfortunately, mosquitoes are part of the natural environment and only so much can be done. The mosquito season is usually over by mid-September.
Is there anything you can do to help? Yes! Below are some tips how you can assist in controlling mosquitoes around your home.
Remove their habitat (where they live and breed)
- Eliminate standing water in rain gutters, old tires, flower pots, buckets, plastic covers, toys or other containers where mosquitoes can breed.
- Empty and change the water in bird baths, pet water bowls, fountains, wading pools, rain barrels and potted plant trays every few days to destroy potential mosquito habitat.
- Drain or fill temporary ponds or pools of water with dirt.
- Keep hot tub & swimming pool water treated and circulating. 

Ways to prevent your exposure to mosquitoes
- Use repellent products with Deet or Recardin and follow label directions and precautions closely.
- Use head nets and wear loose-fitting long sleeves and long pants if you venture into areas with high mosquito populations.
- Stay inside during the evening when mosquitoes are most active.
- Make sure window and door screens are "bug tight."
- Replace your outdoor lights with yellow "bug" lights which tend to attract less mosquitoes than ordinary lights. The yellow lights are NOT repellents, however.
- Avoid using a bug zapper as this kills the beneficial bugs that feed on the mosquitoes!
