Step-by-step explanation:
Insecticides and rodenticides can only be installed by professionals who have the necessary training and certification. These professionals are typically licensed pest control technicians or exterminators.
The Environmental Protection Agency (EPA) in the United States administers the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and registers all pesticides legally sold in the country. This act ensures that only qualified individuals can handle and apply insecticides and rodenticides.
It is important to only hire trained professionals to install insecticides and rodenticides to ensure they are applied safely and effectively, minimizing the risks to humans, animals, and the environment.
