We own a 3100 sq.ft. home. We discovered evidence of active termites in opposite corners of the house. We called four pest control companies. Orkin offered us the best warranty for the price and their treatment plan to get the situation under control was the most appealing to us. They were here two days in a row: six hours the first day and four hours the second day. At one point, there were three Orkin trucks in front of our home at one time. Their technicians were excellent and courteous. Our infestation of subterranean termites was serious. They trenched around the entire outside perimeter of the house with Termidor. They drilled into every area concrete was touching the house including inside the garage, along the back patio and across the front stoop. We have a bi-level home. They pulled back carpet in areas inside the home where they felt problems could potentially exist because of active evidence in the upper level, (even though there was no present evidence in the lower level in the same area,) and drilled into the foundation. They pulled back carpet in another corner of the home and drilled along a settlement crack where one infestation was obvious. They drilled into the foundation along the wall where active termite evidence existed. Active termite evidence in our case meant termites were eating through the drywall and creating exit holes in our walls. We were told, (by all pest control companies that gave us estimates,) only mature termite colonies swarm. We had two swarmings. They "spray foamed" inside the walls in all areas where active termite evidence existed. They discovered a third affected area in our garage which we missed. We have two full bathrooms on our lower level; they installed a "bath trap" door in both lower level bathrooms to be able to check for future termite activity easily. We were offered a one year warranty, three year warranty and five year warranty. We chose the five year warranty. Only one, local company offered a lower price, (just slightly under $1K,) but would do nothing more than trench the perimeter of the home. Terminix offered a price tag very similar to Orkin but with a different treatment plan and only a one year warranty period. The fourth, local company offered a treatment plan similar to Orkin but with a price tag of about $3600. We have never dealt with a termite infestation in the past, so we have nothing to compare this experience to, however, we were thoroughly impressed with the job Orkin did and will definitely continue to use them for future preventative treatments.
