Mosquito Spraying

Mosquitoes can be an annoying, serious problem in our environment. They interfere with work and spoil hours of leisure time. Their attacks on farm animals can cause loss of weight and decreased milk production. Some mosquitoes are capable of transmitting diseases such as malaria, yellow fever, dengue, filariasis and encephalitis – St. Louis encephalitis (SLE), Western Equine encephalitis (WEE), LaCrosse encephalitis (LAC), Japanese encephalitis (JE), Eastern Equine encephalitis (EEE) and West Nile virus (WNV) and Zika Virus to humans and animals.

Adult mosquitoes prefer to rest on weeds and other vegetation. We can reduce the number of areas where adult mosquitoes can find shelter by cutting down weeds and grass. To further reduce adult mosquitoes harboring in vegetation, insecticides may be applied to the lower limbs of shade trees, shrubs, and other vegetation. Paying particular attention to shaded areas, apply the insecticides as coarse sprays onto vegetation, walls, and other potential mosquito resting areas. Stagnant bodies of water are breeding havens for mosquitoes. Larvicides are applied directly into the water to control large mosquito population outbreaks.

Only adult mosquitoes require a blood meal and bite animals-warm or cold blooded-and birds. Stimuli that influence biting (blood feeding) include a combination of carbon dioxide, temperature, moisture, smell, color, and movement. Male mosquitoes do not bite, but feed on the nectar of flowers or other suitable sugar source. Acquiring a blood meal (protein) is essential for egg production. Female Toxorhynchites actually can’t obtain a blood meal and are restricted to a nectar diet. Of those female mosquitoes capable of blood feeding, human blood meals are seldom first or second choices. Horses, cattle, smaller mammals, and/or birds are preferred choices.

Mist Sprayers use the horizontal fan to create an air volume that blows across liquid spray droplets, breaking them up in a swirling air vortex that deposits them into the treatment area. These droplets directly kill active adult mosquitoes and also deposit residual sprays on vegetation and establish a perimeter strip of barrier protection which mosquitoes are physically capable of flying across, but simply will not travel through. This is the safest and cost efficient application method because you do not have to put insecticide directly onto the area to be protected. This has proven to be exceptionally effective for homesteads, campgrounds, livestock, feedlot, shelter areas, resorts, golf courses, country clubs, municipalities, public schools, parks, hunting lodges, and more. Residual sprays can be applied as barrier treatments to tall grasses, weeds, trees, shrubs, fences, and other places where they may harbor to help reduce adult mosquito populations. Treat areas just before the period of maximum use for best results.

The versatility of the A1 Mist Sprayer provides you the tool to effectively spray for mosquitoes, gnats, flies, and ticks with safer chemicalts. You control the rate, frequency, and direct the spray to the application area.


Mist Sprayer applications use less active product because the swirling vortex action penetrates the thickest vegetation and reaches the insect pest instead of expecting it to fly through a fog. A1 Mist Sprayers will reach 100 to 300 feet (depending on conditions) and will give you more control of your application area, allow you to take advantage of the more uniform coverage, and increase overall effectiveness!

The mosquito goes through four separate and distinct stages of its life cycle: Egg, larva, Pupa, and Adult. Each of these stages can be easily recognized by its special appearance. How long each stage lasts depends on both temperature and species characteristics. For instance, Culex tarsalis, might go through its life cycle in 14 days at 70 degrees and take only 10 days at 80 degrees. On the other hand, some species have naturally adapted to go through their entire life cycle in as little as four days or as long as a month.

mosquito life cycle

Egg + -

Eggs are laid one at a time or attached together to form “rafts”. They float on the surface of the water. In the case of culex and Culiseta species, the eggs are stuck together in rafts of up to 200. Anopheles, Ochlerotatus, Aedes, and many other genera do not make egg rafts, but lay their eggs singly. Culex, Culista, and Anopheles lay their eggs on the water surface while Aedes and Ochlerotatus lay their eggs on damp soil that will be flooded by water. Most eggs hatch into larvae with 48 hours. Others might withstand subzero winteres before hatching. Water is a necessary part of any species egg hapitat.

Larva + -

The larva lives in the water and comes to the surface to breathe. Larvae (larva plural) shed (molt) their skins four times, growing larger after each molt. Most larvae have siphon tubes for breathing and hang upside down from the water surface. Anopheles larvae do not have a siphon and lie parallel to the water surface to get a supply of oxygen through a breathiing opening. Coquillettidia and Mansonia larvae attach to plants to obtain their air supply. the larvae feed on microorganism and organic matter in the water. During the 4th molt the larva changes into a pupa.

Pupa + -

The pupal stage is a resting, non-feeding stage of development, but pupae are mobile, responding to light changes and moving (tumble) with a flip of their tails towards the bottom of protective areas. This is the time the mosquito changes into an adult. This process is similar to the metamorphosis seen in butterflies when the butterfly develops in the cocoon stage, from a caterpillar to an adult butterfly. In culex species in the southern United States this takes about 2 days in the summer. When development is complete, the pupal skin splits and the adult mosquito (imago) emerges.

Adult + -

The newly emerged adult rests on the surface of the water for a short time to allow itself to dry and all its body parts to harden. The wings have to spread out and dry properly before it can fly. Flood feeding and mating does not occur for a couple of days after the adults emerge.
