Pest-deterring barriers are described herein. The barriers are configured to attach to a structure in such a way so as to provide a physical barrier that prevents pests from entering an enclosure. The pest-deterring barriers are made of a material that deters pests from approaching, touching, or traversing the barrier. The pest-deterring barriers have an attachment portion for attaching to a structure and an active barrier portion made of the pest-deterring material. The barrier portion can be easily removed and exchanged periodically. Replacement barrier portions are described herein, as are methods of deterring pests using the described pest-deterring barriers.
