MGMC guarantees that the mosquito population in the treated location should be reduced substantially for the term of the mosquito season (March-October) as long as you maintain services. Should the population not be reduced substantially with your scheduled service, we will come back and do a re-treatment at no extra charge. This guarantee covers one re-treatment during the re-treatment period (between scheduled services). There is a limit of 4 retreatments per season. The One Shot Guarantee only guarantees re-treatment, and no monies paid will be refunded. *This guarantee is only provided with recurring services. This guarantee does not cover retreatment needed because scheduled treatment could not be performed properly due to customer issue such as, but not limited to, customer having other workers or visitors in the yard at the time of service.
