As a research-based pest control firm, Landmark Pest Management uses scientific data and the results of field tests to inform our green pest control practices. Landmark’s Integrated Pest Management program seals pests out and prevents infestations by first relying on pesticide-free strategies designed to stop insects and rodents before they become a problem. Pesticide-free methods include insect light traps, air curtains, structural exclusion, and habitat modification to control pests.
