Which method is used in Prevention/Mechanical Barriers?

Using protective clothing and screens is a method of creating mechanical barriers to prevent pests from entering areas where they could cause harm. This method physically blocks pests, thereby reducing their ability to access food sources, reproduce, and establish infestations. For instance, installing screens on windows and doors helps prevent insects from entering living spaces, while wearing protective clothing can guard individuals against bites or stings from pests like ticks or mosquitoes.

Habitat alteration, while relevant in pest management, involves modifying the environment to make it less conducive for pests but does not involve a physical barrier. Pesticides are chemical solutions used to kill pests rather than preventing them from accessing an area, while biological predators refer to using natural enemies to control pest populations, which is a different approach entirely. Hence, protective clothing and screens provide direct and effective mechanical barriers to prevent pest intrusion.
