The Beautification and Facilities Division of Public Works is responsible for mosquito abatement inside the City-Limits.  Mosquito control is essential, not only to eliminate the biting nuisance, but to reduce the risk of viruses such as West Nile and Zika.  We use a chemical called “Aqua-Reslin” utilizing a truck mounted ULV (Ultra Low Volume) fogger, which is ideal for eliminating both adult mosquitos as well as their larvae. Spraying occurs two to three times per week, unless weather dictates otherwise. We cannot spray the entire city each week, but we do attempt to blanket multiple neighborhood areas each week. It generally takes two or three weeks of spraying to reach all areas within the city limits. 

Please contact (843) 665-3236 to submit a work order if you live in the City of Florence limits and need mosquito control assistance.  

NOTE:  If you are a beekeeper, please make sure to contact us so that we know your location in order to prevent spraying near your hives.

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.

What is Ultra Low Volume (ULV) fogging?


Vectorfog™ fogging equipment is used predominately for the application of disinfectants, biocides, fungicides and pesticides. Our foggers generate a fog or mist formed of Ultra Low Volume (ULV) droplets between 5-50 microns (μm) in diameter. Studies have shown that droplets of this size are ideal to tackle pathogens, vector carriers and pests. In addition formulations can be applied in concentrations of 10-90% and at flow rates of up to 0.5 litres per minute (30 litres per hour) making them more efficient in the Volume Median Diameter (VMD) spectrum.

Conventional sprayes, reach insects less effectively than ULV technology. This is because conventional sprayers spray larger droplet sizes in between 100-200 microns, which don’t fully cover the whole area being sprayed. Apart from the droplet size they produce, manual sprayers can be very time consuming and labour intensive. Although motorized versions spray quicker, there are not suitable for indoor use, as they leave surfaces very wet and produce exhaust gases. Manual sprayers are ideal when you need to pray close up, in places such as patio areas and gardens.
Thermal Fogging, heats up pesticides or disinfectants mixed with oil producing a very dense and visible fog formed of droplets of around 10 microns in size. Thermal fogging is ideal for exterior use to disinfect, combat vector carriers and pests. This method of fogging is not suitable for applying in closed indoor spaces due to the exhaust gases they produce. VectorFog has begun to manufacture a dual function thermal fogger that can also fog water based solutions. For more information please send us an email to info@vectorfog.com
ULV Fogging, works by compressing pesticides or disinfectants through a specially designed nozzle, producing a fine cold mist or aerosol. Electric portable versions are particularly ideal for indoor applications as they don’t produce exhaust gases and are less noisy. These machines can apply both oil and water based solutions.

 

Main Applications
VECTOR AND PEST CONTROL

Vector carrying insects and pests such as mosquitoes, flies, fleas, mites, and cockroaches are the cause of most common biological disease transmissions in the world today. It is generally accepted by industry professionals that fogging is the most efficient method of control, as only small amounts of pesticides get used in the process.

FLYING INSECTS

 

 alt= Mosquito Mosquitoes like the Aedes aegypti and flies such as the Black fly, form a major group of disease carrying vectors. These transmit a huge number of infectious diseases to humans, including Malaria, Dengue fever, Yellow fever, Typhus, and the Zika virus. Flying insects can also affect livestock and destroy crops having a damaging effect on agriculture. Examples include Mosquitoes, Blow Flies, Bottle Flies, Stable Flies, Fruit flies, Bean Flies and Lygus. Thermal fogging is used to control the population of these insects in towns and farms.

 

HOUSEHOLD INSECT PESTS

 

Bed bug Bed bug Insects are the most common pest problem in households. An increasing public health problem in cities and towns, typical insect pests include Bed bugs, Fleas, Ants, Wasps, Moths and Cockroaches. Although not all of these pests carry diseases, they can spread rapidly leading to large infestations which can be difficult to control. Some of them can also cause skin irritation and allergic reactions. Fogging is used to eradicate them after an infestation has occurred.

 

LIVESTOCK PARASITES & PESTS

 

Red mite Red mite Livestock parasites can be detrimental to livestock production. As animal production has become more intensive, the threat of parasitic disease has also increased. These parasites range from flying insects to lice and mites which feed on the blood, skin, and hair of animals. These include Mosquitoes, Black flies, Hog Lice, Itch Mite, Ear Ticks, Sticktight Fleas and Red Mites. Hog lice for example can carry swine flu or swine pox, whilst Red Mites feed around the breast and legs of hens, causing pain, irritation, and decrease egg production. Fogging can be used to eradicate parasites living in empty sheds or stables prior to housing. Continuous disinfection of livestock housing using a fogger tends to be done thought the breading cycle.

 

EXAMPLES OF INSECTICIDES USED FOR FOGGING

• Malathion: an organophosphate water based insecticide Ideal Equipment: Cold Fogger (interior) / Water Based Thermal    Fogger (exterior)
• Synthetic pyrethroid: an organic based compound similar to natural Pyrethrins produced by the flowers of the pyrethrum    plant. Piperonyl Butoxide is sometimes added to Pyrethrins to increase their potency.Ideal Equipment: Cold Fogger    (interior) / Oil based Thermal Fogger (exterior).

Disinfection

Pathogenic microbes such as virus, fungi and pathogenic bacteria are the main cause of airborne or direct contact diseases affecting animals and humans. Studies show the application of disinfectants and biocides via aerosol or fogging significantly reduce the number of viable infectious pathogens. Foggers produce micro droplets that float in the air for around 10 minutes after application, reaching the most inaccessible parts where conventional cleaning or spraying can’t reach.

PATHOGENIC BACTERIA

 

Ecoli Ecoli Pathogenic bacteria contribute to many illnesses and infections whether food borne, water borne or air borne. These include diseases such as E-coli, MRSA, C. difficile, Campylobacter, Legionella and Salmonella. Unhygienic food preparation, water storage and air conditioning systems can harvest as well as spread these diseases. Bacteria such as MRSA and C. difficile are especially troublesome in hospitals, prisons and nursing homes, where patients with open wounds, and weakened immune systems are at greater risk of infection.

 

VIRUS
Influenza Influenza Viral infections make up around one third of cases of food poisoning in developed countries. Examples of these viruses include the Norovirus and Rotovirus. Other common viral infections include cold viruses and Seasonal influenza (the flu). An increasing concern due to a growing global population are animal or bird to human transmissions such as H1N1 (swine flu), and H5N1 strain of bird flu. Disinfection of surfaces using a fogger is essential to stop the spread of these infections.
