The answer to 'how long does rat treatment last' is that the effectiveness of rat treatment can vary depending on the specific situation and the methods used. Generally, a professional pest control treatment for rats will provide protection for several months, but may need to be repeated periodically to ensure ongoing control.
Comprehensive rat treatment typically involves a combination of methods, such as sealing entry points, removing food sources, and applying rodenticides or traps. The duration of effectiveness can depend on factors like the size of the infestation, the thoroughness of the treatment, and whether any new rats are able to enter the home. Most professionals recommend follow-up inspections and potential retreatment every 3-6 months to maintain control.
