You got that right! before I started my own company, I worked for another company that had the pest control contract for both Navy bases in Jacksonville. All applicators on base had to be certified (ghp, l&0, wdo) for what they were doing. at the time, all I had was L&O so they put me on a four wheeler with ant bait and a 15 gallon sprayer and my job was to keep the fire ant mounds at or under one mound per acre (per contract). I patrolled about 1500 acres! I tried everything except blanket spraying(not allowed) and when I came back through the next month, the mound would be moved within a 20 foot radius of original location. I rodded mounds with talstar, tried rings of bait at varying distances from mound. Frustrating. I started my own company after a year.
