What is a major method of controlling pests in some situations?

Using screens and other barriers is a significant method of controlling pests as it involves physically preventing pests from accessing certain areas or plants. This approach creates a physical barrier that can be effective against a variety of pests, including insects, rodents, and larger animals. It is particularly useful in protecting gardens, crops, and stored products without the need for chemical applications. Barriers can include screens, netting, or even physical structures that limit pest movement and entry, thereby reducing the likelihood of infestations while being a more environmentally friendly option compared to chemical methods.

This method also has the added benefit of being non-toxic, making it safe around children and pets, and can often be a more sustainable option for long-term pest management. Integrating barriers with other methods may offer even more effective pest control strategies by creating a holistic approach to managing pests in various environments.
