Zenivex^®: Reduced-Risk Mosquito Control That Delivers

At Central Life Sciences, our commitment to protecting the public’s health and our environment is reflected in the Zenivex^® line of low-toxicity adulticides, a lineup that has grown to be one of the industry’s most comprehensive collections of reduced-risk solutions.

Zenivex^® mosquito adulticides provide quick, permanent knockdown and reliable control of adult mosquito populations in any mosquito habitat. With three formulations ready-to-use for aerial, ground, or hand applications, Zenivex^® makes it easier to manage outbreaks and reduce disease transmission, while keeping people, pollinators, and the planet in mind.

Reduced Risk, Elevated Control

Zenivex^® products feature Etofenprox, a unique, non-ester pyrethroid molecule that is highly effective on adult mosquitoes.

The EPA has classified Etofenprox as a reduced-risk active ingredient due to its:

• Low toxicity to birds and mammals
• Dried foliar residues that are not harmful to honey bees
• Lack of synergists, meaning no Piperonyl Butoxide (PBO)
• Improved safety for operators and bystanders

This reduced-risk classification makes Zenivex^® adulticides an ideal choice for mosquito control programs in both urban and rural settings.

Zenivex^® Formulation Benefits

Whether you’re treating a dense neighborhood, a pasture, or above agricultural land, Zenivex^® adulticides offer the flexibility and performance you need. All formulations are approved for use over cropland, pasture, and rangeland, with no aquatic setbacks required.

Zenivex^® Product Options:

• Zenivex^® E20 mosquito adulticide: Oil-dilutable ULV-ready formulation that can be used diluted or undiluted
