If only it was that easy! The fact of the matter is, once pests are sighted, it might mean the population is out of control. When a homeowner sees one mouse, or one cockroach, or one silverfish, it is usually an indication that the infestation has grown large enough for pests to seek new nesting sites or food sources. If an Integrated Pest Management Program is not completed, the source of the infestation will continue to produce new pests. PermaTreat's Pest Protection Plan provides year-round pest maintenance with only four scheduled visits per year to minimize applications, but includes free callback service.
