What is an example of a physical pest control method?

Physical pest control methods involve techniques that eliminate pests without the use of chemical pesticides. Traps and barriers are effective examples of this category because they physically block pests from entering an area or capture them, preventing further infestations. For instance, using mesh screens can keep insects out of buildings, while traps can capture rodents or specific insect pests.

Pesticide spraying and soil fumigation involve chemical applications, which do not fit the definition of physical methods. Biological control refers to the use of natural predators or parasites to manage pest populations, which is also a non-physical approach. Therefore, traps and barriers stand out as the only option that directly involves manipulating the environment or using devices to manage pest presence without relying on chemical substances.
