Instructions for use

Both the insecticide and the spraying equipment must be approved by the WHO Pesticide Evaluation Scheme (WHOPES), and staff must be fully protected.

When choosing an active ingredient, contact your technical referent for advice. Resistance of mosquitoes to certain active ingredients, non- compatibility of the active ingredient with other activities, availability of products and also incoherence of legislation in different countries can turn the choice of a product into a complicated procedure. Also in addition to the active ingredients listed above, new products are foreseen to enter the market.

Do not use products having pyrethroids as an active ingredient in contexts where pyrethroid- impregnated mosquito nets are used.

Staff must be properly trained and appropriate protective equipment must be provided and utilised systematically.

Use wettable powder only for its intended use. Do not use wettable powder to impregnate nets, or on clothes to eliminate body lice. See "Public Health Engineering in Precarious Situations", MSF, 2nd edition, 2010: T.B. 7.17 Impregnation of nets, clothing and curtains, and T.B. 7.18 Insecticidal dusting, for appropriate products.

Dosage: see table above for recommended dose of active ingredient per m2. See "Public Health Engineering in Precarious Situations", MSF, 2nd edition, 2010: T.B. 7.15 Insecticide Residual Spraying campaign, for specific calculations.

​Effective vector control measures must be implemented in all MSF projects located in malaria-endemic zones.

Vector control activities must be planned and organized with the help of specialists in order to correctly define the species of the vector present and the type of product to be used.

For advice on the specific application method, see the guide "Public Health Engineering in Precarious Situations", MSF, 2nd edition, 2010, chapter T.B. 7.14 Insecticide residual sprayer, and/or contact your technical department.

The spraying of insecticides at the recommended strengths poses little or no risk if the appropriate precautions are taken to protect both the staff involved in vector control and the community concerned.

Exposure of skin, especially mucous membranes, to deltamethrin can cause temporary tingling and a burning sensation known as paraesthesia. Toxicologically this has no significance beyond the immediate discomfort.

Caution

The application of an insecticide must always be carried out after agreement with the local authorities. In some countries application of insecticides can only be carried out by staff holding a valid license or certification from the government.

The purchase and use of some active ingredients listed above is prohibited in some regions. Consult your technical referent for more information.

Prior to application of an insecticide the population must be informed properly of the nature of the activity, its benefits and risks.

Precautions for Use

The following routine safety measures are to be observed at all times:

  • Provide clear and thorough training to the staff responsible for applying insecticides
  • Keep insecticides out of the reach of children
  • Do not eat, drink or smoke during the application of insecticides
  • Do not inhale powder and avoid direct contact with eyes and bare skin
  • Wear protective clothing (mask, goggles, overalls, gloves, boots and head-cover)
  • Before application, remove or cover all food and utensils
  • Give operators clear instructions about storage, handling, dilution, application and individual protection
  • Do not dispose of residues and unused or expired in ponds or rivers as insecticides are highly toxic to fish
  • Refer to your technical referent for appropriate disposal procedures

Storage

  • Store separately from food and beverage
  • Avoid exposure to direct sunlight
  • Store in a dry, cool and well ventilated space
  • Keep out of the reach of children
