The answer to 'how long does centipede treatment last' is that the effectiveness of centipede treatment can vary depending on the specific treatment method used and the severity of the infestation. Generally, professional-grade centipede treatments can provide effective control for several months, often 3-6 months or longer. However, some DIY treatments may only last 4-8 weeks before the centipede population starts to rebound.
It's important to follow the instructions carefully and reapply the treatment as recommended to maintain long-term control. Factors like weather, humidity, and the presence of conducive conditions in the home can also impact how long the treatment remains effective.
