The answer to 'how often for centipede control' is that centipedes should be treated as soon as they are spotted in the home, and preventive treatments should be done every 3-6 months. Centipedes are nocturnal pests that can quickly infest a home, so it's important to address them promptly. Preventive treatments with a residual insecticide around the home's perimeter and in cracks and crevices can help keep centipedes at bay between infestations.
For an active centipede infestation, a pest control professional should be called to properly identify and treat the problem. They will use targeted insecticides and other methods to eliminate the centipedes. Ongoing prevention is key, as centipedes can re-infest quickly if conditions are favorable.
