The Beautification and Facilities Division of Public Works is responsible for city-wide mosquito control. The Mosquito Control vehicle sprays during the evening hours starting in the summer and ending in the fall, during the primary mosquito nuisance season. Please contact (843) 665-3236 to submit a work order if you live in the City of Florence limits and need mosquito control assistance.

General Information Regarding Mosquito Control:

Mosquito control manages the population of mosquitoes to reduce their damage to human health, economies, and enjoyment. Mosquito control is a vital public-health practice throughout the world and especially in the tropics because mosquitoes spread many diseases, such as malaria.

Mosquito-control operations are targeted against three different problems:

  1. Nuisance mosquitoes bother people around homes or in parks and recreational areas;
  2. Economically important mosquitoes reduce real estate values, adversely affect tourism and related business interests, or negatively impact livestock or poultry production;
  3. Public health is the focus when mosquitoes are vectors, or transmitters, of infectious disease.

Disease organisms transmitted by mosquitoes include West Nile virus, Saint Louis encephalitis virus, Eastern equine encephalomyelitis virus, Everglades virus, Highlands J virus, La Crosse Encephalitis virus in the United States; dengue fever, yellow fever, Ilheus virus, malaria, and filariasis in the American tropics; Rift Valley fever, Wuchereria bancrofti, Japanese Encephalitis, chikungunya, malaria and filariasis in Africa and Asia; and Murray Valley encephalitis in Australia.

Depending on the situation, source reduction, biocontrol, larviciding (control of larvae), or adulticiding (control of adults) may be used to manage mosquito populations. These techniques are accomplished using habitat modification, pesticide, biological-control agents, and trapping. The advantage of non-toxic methods of control is they can be used in Conservation Areas.

The mosquito life cycle is composed of four stages: eggs, larval, pupae and adult.

Stage 1: Eggs

Only female mosquitoes have the ability to lay eggs. In order to develop eggs, the female needs a blood meal.With each blood meal, the female can lay several hundred eggs. The eggs are laid in or around water and will attach to one another, forming a raft. Individual eggs will float independently. After 24 to 48 hours, the eggs will hatch and release larvae.

Stage 2: Larvae
Mosquitoes spend approximately seven days to complete development of the larval stage depending on food and temperature conditions.

Stage 3: Pupae
A week to ten days after the eggs hatch, the larvae transform to pupae. At this time, they can breathe oxygen. However, they cannot feed (bite). Mosquitoes spend one to two days in the pupae stage.

Stage 4: Adult
Once the mosquitoes have reached adulthood, they will feed on nectar; only the female mosquito will seek out a blood meal for reproduction. The adult mosquito lives for a period of six to eight weeks. A female will lay several batches of eggs during her life.
