DDT Questionnaires

Every three years, Parties that produce or use DDT are required to report the conditions of such production or use to the Secretariat. This reporting obligation is fulfilled by completing a DDT questionnaire that was adopted by the third meeting of the Conference of the Parties (COP-3) to the Stockholm Convention.

Paragraph 4 of Part II of Annex B to the Convention stipulates the DDT reporting requirements, including the amount used, conditions of use, and its relevance to disease management strategies. Parties are also able to report other information relevant to the evaluation of the continued need for DDT for disease vector control.

The questionnaire is composed of four main sections:

  • Section A: Production and Use of DDT
  • Section B: DDT Alternatives (Insecticides, methods, and strategies)
  • Section C: General Human and Environmental Safety Issues
  • Section D: Systems Strengthening in Disease Vector Control

The next reporting deadline is 30 June 2024 for the three-year period from 2021 to 2023.

The Secretariat has made available an online questionnaire on the reporting on the production and utilization of DDT, as well as other information relevant to the evaluation of the continued need of DDT for disease vector control. The questionnaire is available in English, French and Spanish and can be accessed through the following link:


Parties are kindly invited to report on their DDT use or production for the period 2021-2023 mainly through the online version of the DDT questionnaire. Credentials to the questionnaire are sent to SC OCPs and only one submission from each country is allowed.

The  questionnaire is available for download in word and PDF format in the six (6) official languages of the United Nations here below to facilitate national coordination during the completion of the questionnaire.
