Our naturally derived mosquito control service uses a synthetic derivative of the chrysanthemum flower containing pyrethrin. Pyrethrins are commonly used to control mosquitoes, moths, flies, ants, and other pests. This product is completely safe for your family and pets, so you don't have to worry about taking the extra steps during the treatment process. If you are not satisfied with our work, we will come back out and re-treat your lawn no questions asked.
