Identify a common physical control method in pest management.

Physical control methods in pest management involve using physical barriers or devices to prevent or eliminate pests without relying on chemical treatments. Traps or barriers serve this purpose effectively by physically obstructing pests or capturing them. For instance, traps can be designed to catch rodents or insects, while barriers can include fencing or netting that prevents pests from accessing certain areas or crops.

Pesticide sprays do not fall under physical control methods, as they utilize chemicals to manage pest populations. Aromatherapy for repelling pests, while a creative idea, is not a recognized physical control method but rather leans towards behavioral modification or alternative methods. Biological controls involve the use of natural predators or parasites to control pest populations, which is distinctly different from physical methods since it relies on living organisms rather than physical mechanisms.
