Alex from Homestead, Iowa writes

What is the residual of Cyzmic CS when used outdoors to treat wasps and other insects on plants? Does this harm plants or flowers in flower beds.


Cyzmic CS is labeled safe to apply to bushes, trees, shrubs, flowers and ornamentals and will leave a residual of about 30 days. We do advise to refrain treating blooms or flowers when pollinators are active.  Please view our How to Treat for Wasps, Hornets, and Yellow Jacket Treatment Guide for more information.
