Hendry County is in contract with Clarke Environmental to  help reduce the nuisance and public health threat posed by mosquitoes this  summer. Founded in 1946, Clarke is a leading force for mosquito control,  offering service and education to cities, mosquito abatement districts and other  governmental entities throughout the U.S. And with local offices in Florida,  Clarke has the assets and expertise to provide an effective mosquito control  program for the residents of Hendry County.

The Hendry County mosquito control program calls for Clarke to  provide surveillance of the mosquito population, larval control and adult  mosquito control. This integrated program combines forecasting and monitoring  with application of the most effective control agents, to ensure that control  efforts achieve maximum results, with minimum impact on the environment.

Surveying, Mapping and Forecasting

The first step of Clarke's integrated control plan is to survey and map the mosquito population in the area and forecast the arrival of mosquito broods.

Surveillance and Monitoring

Once Clarke knows the history of a breeding site, they begin regular inspections of target problem areas.  This routine surveillance determines the distribution and density of mosquito populations and their proximity to human living areas.  Light traps keep Clarke abreast of emerging mosquito populations and alerts the company when annoyance threshold levels are reached.  Additionally, calls from the public help Clarke identify areas of heavy infestation.  This information is important to help Clarke determine when annoyance levels reach the point where it is necessary to spray for adult mosquitoes.


Larval control, a key element of a comprehensive mosquito control program, began earlier this summer to help reduce mosquito populations in Hendry County.  Designed to attach the mosquito in the aquatic larval stage, before they are air borne, larviciding involves treating standing water with insecticides.


Adulticiding has been recognized as an extremely important part of any integrated pest management program.  Adulticiding attacks adult mosquitoes with a truck-mounted and/or aerial application of ultra low volume spray.  Treatments are needed when mosquito populations are at bothersome levels or indicate the presence of mosquito-borne illness, such as West Nile Virus.  All insecticides used have been approved specifically for this purpose and are regulated by the Environmental Protection Agency (EPA).

Yard & Home Checklist

In addition to Hendry County's mosquito control initiatives, residents can take a number of steps to reduce mosquito populations around their homes this summer, including:

Remove or empty water in old tires, tin cans, buckets, drums, bottles or other places where mosquitoes might breed.

*Empty plastic wading pools at least once a week and store indoors when not in use.

*Drain unused swimming pools and keep dry.

*Change water weekly in bird baths, plant saucers and trays.

*Store boats covered or upside down.

*Water bowls used by pets should be emptied and refilled daily.

*Fill holes around home that may retain water.

*Keep gutters around home in good repair to avoid water build-up.

*Keep weeds and grass cut short, as adult mosquitoes look for shady places to  rest during hot daylight hours.

*Be sure screens in homes are intact and tight-fitting to prevent entry of insects.
