The synthetic insecticides in this section have been designed for use on lawns. Many of those products use a new form of pesticide chemistry called "pyrethroids". Pyrethroids are synthetic materials designed to imitate natural pyrethrum. These synthetic materials have the basic chemistry of pyrethrins but are modified to improve persistence, and insecticidal activity.

Be sure to check the Active Ingredient for each product to be sure you understand what is in the product and how much chemical is being used.
