Our equipment is made and designed for large lots. This means we can treat large lots with more speed and better coverage. With a combination like that, we are able to provide our services at a more reasonable rate for large lots. The quarterly granules I use are good for fire ants, spiders, fleas, ticks, grub worms, ect. It only takes one treatment, and you will be free of fire ants for one year, guaranteed. Our product is used on many golf courses and is an excellent solution for the entire year.
