The answer to 'when to treat for pest control' is that the best time to treat for pests depends on the specific type of pest and the location. In general, it's best to treat for pests as soon as you notice signs of an infestation, rather than waiting until the problem becomes severe. This helps prevent the pests from spreading and causing more damage to your home.
For many common household pests like ants, cockroaches, or rodents, it's a good idea to have a professional pest control technician inspect your home and develop a treatment plan at least once or twice a year. They can identify any potential problem areas and recommend the best course of action to keep your home pest-free.
