RESIDUAL SPRAYINGRESIDUAL SPRAYING

Most widely used method of vector controlOne of the most effective method for obtaining rapid large scale impact at an affordable costIndoor residual spraying is mainly to reduce survival of vectors entering houses

RESIDUAL SPRAYINGRESIDUAL SPRAYING

Use high volume of insecticides

Used for routine anti adult and anti larval work

Commonly used sprayers are:

Stirrup pump Compression pump Knapsack sprayer

Space spray treatmentsSpace spray treatments

A space spray – technically a fog Hundreds of millions of tiny droplets less than 50 µm in diameter are dispersed into the air Efficacy lasts till the droplets remain airborne.Space sprays are applied mainly as Thermal Fogs or Cold Fogs.

  Rechargeable Backpack Sprayer

Sprays up to 120 gallons on a single charge

Variable–speed pump and adjustable nozzle allow for light to heavy–duty spraying.

Ultra–comfortable, ergonomically designed tank has a full back pad and thickly padded shoulder harness.

  FOGGINGFOGGING

Cold fog Cold fog Cold fogs are formed by passing through

High-pressure nozzles High-velocity vortex of air.

Spray droplets are generated without any external heat.

Volume of spray is minimum Ultra-low-volume insecticide formulations are commonly used for such applications.

Equipment for Cold Fog Application

Equipment for Cold Fog Application

Hand-carried cold foggers

Vehicle-mounted cold foggers

Aircraft application of cold fogs

Cold FogCold FogAdvantagesAdvantages

Lower application cost and increased acceptability

Reduced operator exposure

Environmental friendly

Application is more efficient

No traffic hazard as the fog is nearly invisible

Cold FogCold Fog

DisadvantagesDisadvantagesDispersal of the spray cloud is difficult to observe

Higher technical skills and regular calibration are required for efficient operation of equipment.

Thermal fog Thermal fog

Oil-based Insecticide used

Hot gas is used to vaporize insecticide solution

Vapour hits colder air and condenses to form a dense white cloud of fog

Most of the droplets are smaller than 20 µm.

The hot emission gas is obtained from engine exhaust

Hand-carried thermal foggers

Vehicle-mounted thermal foggers

Aircraft application of thermal fogs

Thermal FogThermal FogAdvantagesAdvantages

Easily visible fog so dispersal and penetration can be readily observed and monitored

Good public relations as people can see something being done about the problem

Low concentration of active ingredient in the spray mixture and reduced operator exposure.

Thermal FogThermal FogDisadvantagesDisadvantages

Bad odour and staining

High cost of diluents and spray application

Householders may object and obstruct penetration of fog into houses by closing windows and doors

Fire risk from machinery operating at very high temperatures with flammable solvents

Can cause traffic hazards in urban areas
