For low to moderate pest infestation levels or to protect and maintain, pest control services are normally performed fortnightly to monthly. However, due to environmental or situational factors, or if an acute infestation occurs, frequent treatments are required. For example, if a home is located near a dengue cluster, regular mosquito protection measures should be implemented to protect against dengue. Poor housekeeping can result in the need for frequent pest control services as well, if the environment is unhygienic, with things such as food scraps or spillage, it will have a higher risk of a pest infestation. Weather is also another factor that may enhance pest prevalence due to their desire to seek shelter indoors, particularly during the rainy season.
