Of the almost 4000 species of cockroaches that exist, only about 6 species have become serious pests of homes and industry in Australia. Being nocturnal creatures, they become more active after dusk or after human activity has ceased for the night. Cockroaches that roam kitchens while occupants are asleep may be residents of the kitchen (hiding by day in cracks and crevices, warm motors of appliances and so on) or itinerant visitors arriving from grease traps, subfloor areas or drainage/sewage networks. Numerous studies have been conducted to investigate the incidence of disease contamination of cochroaches. Salmonella, Staphylococcus to mention some. You do not want that for your family, please take it seriously, pests do not belong in your home or business. Call Pesta La Vista to arrange a pest management plan for your home or business.
