What is a practical approach for landscapers to handle pests without chemicals?

The practical approach for landscapers to handle pests without using chemicals is through Integrated Pest Management (IPM) techniques. IPM is a holistic strategy that focuses on understanding the lifecycle of pests, their natural enemies, and the surrounding environment. This method involves monitoring pest populations and using a combination of biological control, habitat manipulation, and cultural practices, which can include introducing natural predators or altering the environment to make it less conducive to pest infestations.

IPM emphasizes the use of non-chemical control methods as the first line of defense, making it an environmentally responsible choice in landscape management. By promoting biodiversity and utilizing natural pest controls, landscapers can effectively manage pest populations while minimizing harm to the surrounding ecosystem and reducing chemical exposure for humans and wildlife.

The other options, while they may address pest issues in some way, do not align with the principles of sustainable and environmentally-friendly pest management in the same comprehensive manner that IPM does.
