The frequency of pest control in Australia depends on various factors such as the type of pest, the severity of the infestation, the location of the property, and the preventive measures taken. Generally, it is recommended to schedule pest control services every 6 to 12 months to prevent pests from infesting your home or business. However, certain factors may require more frequent pest control services. For instance, properties located near water sources or areas with high humidity may require more frequent pest control treatments to prevent the breeding and spread of pests like mosquitoes and cockroaches. Similarly, properties with a history of pest problems may require more frequent treatments to eliminate pests. Therefore, it is best to consult a licensed pest control professional to assess your specific pest control needs and recommend a suitable treatment plan.
