Vector Control

Imergard™ WP is being positioned as a new active ingredient for indoor and targeted indoor residual spray applications to combat mosquito vectors.

Imergard WP is a new to the world, patented mechanical insecticide that provides a physical mode of action and is designed to be applied as a wettable powder using standard back pack sprayers typically used in IRS applications.


  • Pending EPA approval as a biopesticide
  • Pending WHO PQ approval
  • 100% engineered amorphous alumino silicate


  • Physical mode of action which deters chemical resistance development
  • Stand alone treatment or use as synergist with existing chemical or biopesticides
  • Provide at least 6 months residual activity
  • Powerful, complementary active ingredient to any integrated vector management program


Apply a single layer of IMERGARD WP in areas where mosquitos are found and may hide.

Targeted Indoor Residual Spray:

IMERGARD WP is intended for application as a wettable powder on painted or unpainted walls, ceilings, cracks and crevices, behind and beneath furniture, appliances, garbage cans, window frames and in attics and basements.

Targeted Outdoor Residual Spray:

IMERGARD WP is intended for application as a wettable powder on covered surfaces, e.g. eaves, under stilt houses, patios, outdoor sills, window and door frames and in and around sewer pipes and drains.

For indoor and outdoor applications, the amount of product to be applied will vary within the site but should usually be in the range of 2-5 oz/100 ft2.


If a mosquito does not survive longer than the extrinsic incubation period then no parasites can be transmitted.

Flying mosquitoes generate static charge. Landing on a surface treated with Imergard WP results in static transfer of the active. These particles absorb the protective lipid layer necessary for the mosquito’s survival. As a result, the mosquito will dehydrate.

It has been noted that the mosquito exhibits unusual and unexpected behavior when exposed to mechanical insecticide – the mosquito remains mostly stationary until death.
