Using a light trap to catch flies is an example of which type of pest control?

Using a light trap to catch flies is classified as mechanical pest control because it involves the use of a physical device to capture or kill the pests without the application of chemicals. Mechanical pest control methods rely on physical barriers or traps, rather than on altering the environment or employing living organisms, which distinguishes them from biological or cultural control methods.

In this case, the light trap attracts flies to it, where they become trapped or incapacitated, effectively reducing the fly population without harming the surrounding environment with pesticides. This type of control is particularly useful in situations where chemical treatments are undesirable or where a more immediate, physical method of control is needed.
