Distance IGR is just an insect growth regulator that prevents young from maturing. It does not actually kill anything. A better option would be Safari 20SG Systemic Insecticide with Dinotefuran which is labeled for both soft and armored scale.
Distance IGR is not labeled for fleas or to treat your lawn. We would recommend our Outdoor Flea and Tick Kit so that you will have everything you need to completely eradicate a flea infestation. Please take a moment to look over our Flea Control Guide for more information on treating and preventing this pest.
They are both professional IGRs that are effective if used for the listed pests as directed. Distance IGR controls insects including whiteflies, scales, shore flies, and fungus gnats in indoor (greenhouse, lath and shadehouse, and interiorscapes) and outdoor ornamentals, including flowering and foliage crops, ground covers, shrubs and ornamental trees, non-bearing fruit and nut trees and indoor grown fruiting vegetables. Tekko Pro Insect Growth Regulator makes controlling the insect population simple for Fleas, Roaches, Flies, Mosquitoes, Gnats, Crickets, Litter Beetles and Ants in Commercial & Residential Indoors & Outdoors: Apartments, Dairies, Food Processing Plants, Hospitals, Hotels, Nursing Homes, Office Buildings, Kennels, Restaurants, Sport Stadiums, Supermarkets, Theaters, Warehouses and Lawns.
