A biorepellent matrix structure comprises a resin and first and second microcapsules suspended in the resin. The first and second microcapsules each includes a first shell and a second shell respectively, containing a biorepellent material that is released upon penetration of any of the first and second shells, as for example, by a biological organism. The biorepellent material, such as capsaicin diffuses through the first and second shells at different rates. The different diffusion rates of the biorepellent material together provide a biorepellant matrix structure that exhibits long term protection against the formation of biological organisms that would otherwise accumulate on the matrix structure, and deters organisms from gnawing or chewing the matrix structure.
