Environmentally responsible mosquito control

What to do and how to keep mosquitoes away in a more efficient and less costly manner?

  • Coordinate health, environment and nature protection through the involvement of the competent organisations. It is important to optimise costs and efficiency under the given conditions;
  • Identify the species within the biting mosquito population in order to be able to determine the area to be controlled and the technology to be used;
  • Identify potential water sources based on the flight ranges of identified biting mosquitoes;
  • Map breeding grounds with the help of GPS devices (in floodplains house numbers and street names are of no use);
  • Use methods of environmentally responsible mosquito control:
  • landscaping (it can often be the final solution),
  • physical methods (e.g. drainpipe maintenance/canal dredging),
  • promotion of the proliferation of natural enemies (enemies of mosquito larvae include fish, aquatic invertebrates, etc.),
  • application of natural, microbiological products (Bti, Bs...)
  • finding and treating the wintering grounds of mosquitoes (e.g. drainage channels)
  • Inspect the identified breeding grounds regularly, on a weekly basis;
  • In case microbiological products are used, follow the principle of “only where it is absolutely necessary and only in the amount absolutely necessary”. The goal is to treat the smallest possible area infested by larvae with the greatest possible efficiency;
  • Map breeding grounds on the basis of the “you must look everywhere” principle;
  • The methods used to control the proliferation of adult mosquitoes (imagos) cannot be successfully applied for mosquito larvae control;
  • To ensure effectiveness conduct experiments to check methods which have been tested and proven elsewhere or have been described in literature. If necessary, efforts must be made to develop new methods.

The items listed below are indispensable for safe mosquito control:

  • Biological and ecological knowledge
    • identification of harmful creatures,
    • patterns of egg laying by biting mosquitoes,
    • conditions and habitat types required for the development of mosquito larvae,
    • active period of adult biting mosquitoes (imagos),
    • other conditions required for imagos to become active,
    • conditions required for imagos to suck blood,
    • wintering habits of the different mosquito species,
    • conditions required for natural enemies to appear
  • Bacteriology knowledge
    • knowing the living conditions of microbes when using microbiological products,
    • spore conditions required for the toxic effect,
    • conditions that affect toxicity (not all Bti spores are toxic...)
  • Knowledge of molecular biology
    • nerve physiology,
    • effect mechanism of chemicals and products
  • Medical knowledge
    • side effects of chemicals,
    • side effects on human health,
    • knowing how to offset the effects of overdose
  • Knowledge of geoinformatics
    • knowing how to map breeding grounds
  • IT skills
    • IT skills are indispensable in many fields
