What questions should homeowners ask during a professional termite treatment? Homeowners should find out specifics about the location and extent of termite damage. They should ask for further information on the products and materials that will be applied in and around their home. A federal law requires commercial applicators of "restricted use" products to be certified. The certification program is left up to the state. Homeowners can call the certifying state agencies for further information. They should also be aware of the difference between a repair and a retreat contract which stipulates a company's ultimate responsibility for the job. Homeowners shouldn't hesitate to question their pest control operators about other pests or related pest information. PCOs are well-trained, educated and capable of discussing pests and pest-related public health and property threats. As consumers become increasing aware of and worried about the recent influx of pest-related public health threats they should feel free to contact NPMA or their local PCO to address any issues.
