What is the best long-term control method for managing mice and rats in a building?

The best long-term control method for managing mice and rats in a building is exclusion and sealing entry points. This approach focuses on preventing rodents from entering the structure in the first place, which is crucial for maintaining a rodent-free environment. By identifying and sealing up any potential entry points—such as gaps around doors, windows, vents, and pipes—pest management professionals can significantly reduce the chances of a rodent infestation.

Rodents are adept at finding small openings to gain access, so ensuring that the building is secure plays a vital role in long-term pest control. This preventative measure not only addresses the current population but also mitigates future issues, reducing the reliance on more reactive measures like baiting, trapping, or killing, which are often less effective in the long run if the underlying issue of access isn't resolved.

While baiting, trapping, and clearing outdoor debris are important components of an integrated pest management strategy, they are primarily reactive measures that do not ensure complete control. Exclusion provides a sustainable solution that protects the premises from future infestations.
