- Physical mode of action

- Long-term residual control

- Manages insecticide resistance

- 100% natural, safe and effective

In its 2019 annual report, the World Health Organization (WHO) reported 405,000 deaths from malaria, 67% of which were children under the age of 5 years old. Indoor Residual Sprays (IRS) have been an effective strategy to control malaria transmission and have helped reduce the number of deaths in recent years. However, mosquitos evolved to become resistant to these treatments.

Imergard WP (Wettable Powder) is a mechanical insecticide providing a physical mode of action. It can be applied to interior walls using standard backpack spray equipment. When the mosquito lands on a treated surface, there is a static transfer of Imergard WP particles that absorb the lipid layer necessary for the mosquito’s survival.

Features & benefits

- Pending USA Environmental Protection Agency approval as a biopesticide for targeted IRS applications

- A physical mode of action offers a new resistance management tool to deter cross-chemical resistance development

- A five-year shelf life, so it can be distributed to application sites months or years in advance

- No odor and residents can enter the home immediately after application

- Visual application cues allow sprayers and home residents to see where it has been sprayed

- Applied with standard IRS backpack sprayers

- Produced from a renewable and sustainable resource

Does not heat degrade so can be applied to tin ceilings.
