Safety & Sustainability

Despite the widespread use of insect control methods, including insecticides, over many years, vector-borne diseases are still rapidly increasing. Our approach is an effective new solution, which has been shown to be safe and sustainable in the countries where it has been tested.


  • Our approach relies on the natural mating instinct of a male insect, a method which we believe is more cost-effective and targeted than alternatives.
  • The Oxitec approach is species-specific, unlike other control methods that will not distinguish between the target insect and other insects.
  • There is no significant residual impact to the environment.
  • It can be used as part of a broad IVC (integrated vector control) programme or IPM (integrated pest management) but does not, in itself, involve the use of chemicals in the home or the environment.


  • Male insects are released (male mosquitoes do not bite or spread disease).
  • Oxitec insects are self-limiting so do not persist in the environment.
  • Aedes aegypti mosquitoes only mate and produce viable offspring with other Aedes aegypti mosquitoes, so DNA sequences cannot be spread to other insects by Oxitec mosquitoes.
  • No toxins are introduced into the insects as part of the engineering so there is no harm to birds or animals that eat them.
  • We comply with all national and international legislation. Insects are only transported, evaluated in a laboratory or released into the environment when all relevant regulatory approvals have been met.

Oxitec’s solution was recently recommended by the World Health Organization (WHO) for deployment in operational conditions, and the Pan American Health Organization (PAHO) recently declared it will provide technical support for countries that wish to implement OX513A in the fight against this menacing mosquito. The US Food and Drug administration also released a preliminary finding of no significant impact on a trial of Oxitec’s self-limiting mosquito in the Florida Keys, which concluded that it would not have a negative impact on human health or the environment.
