The invasive caterpillars were ruining our outdoor experience. I called Master and Cohen after seeing one of their trucks in my neighbourhood and was told the demand for their services was super high and the wait for spraying could be well over a week. However, they managed to fit me in within a couple of days. I'm so happy with the quick service and the fact that they listened to my concerns. and heard the stress the insects were causing. I would certainly use this company again to get rid of gypsy moths and for another tree services.
