Long-term benefits of using an insect growth regulator

By Chris Keefer, Technical Services Manager, Professional Pest Management, Syngenta

As we move into the spring season, mosquitoes will become active and start threatening customers’ peace-of-mind. Well-maintained properties, proper inspections, identification of the target pest and reduction of conducive conditions are all key to preventing mosquitoes in urban environments.

Before taking any management steps, review the best practices below to help ensure successful control of container-breeding mosquitoes, such as Aedes albopictus and Aedes aegypti:

  • Complete a pre-treatment inspection of the property
  • Use a larvicide in standing water that may contain mosquito larvae
  • Use proper personal protective equipment, including but not limited to a long-sleeved shirt and long pants
  • Educate customers about how they can help reduce mosquito breeding sites on their properties

Once the mosquitoes are identified, the combination of an adulticide and an insect growth regulator (IGR) is recommended for long-term control. An effective adulticide should be non-phytotoxic, rainfast (to ensure the treatment stays in the target zone) and easily mixable with other products. Demand® CS insecticide features these benefits, plus the power of iCAP™ technology, which releases microcaps of multiple sizes for both immediate and residual mosquito control.

An IGR can complement an adulticide by helping suppress mosquito populations. Archer® IGR interferes with the development process of mosquito larvae, as well as addresses the skip oviposition behavior of Aedes mosquitoes (laying eggs in multiple locations). A female mosquito ovipositing her eggs can move the IGR she has contacted to each of her cryptic oviposition sites. The IGR will then reduce subsequent populations of mosquitoes by decreasing egg abundance, egg hatch rate and adult emergence.
