Which material is known to be damaged by insects?

Wool carpets are known to be susceptible to damage by insects, particularly carpet beetles and moths. These insects are attracted to the natural fibers present in wool, as they can feed on the proteins found in the material, leading to holes and deterioration over time. This vulnerability is particularly significant in environments that promote the presence of insects, such as areas with high humidity or where cleaning and maintenance practices might not adequately address infestations.

In contrast, synthetic materials such as nylon, polypropylene, and silk offer varying levels of resistance to insect damage. Nylon, for example, is not a natural fiber and is less attractive to insects, while polypropylene is even more resistant due to its synthetic composition. Silk, while a natural product, is less commonly used for carpets and typically has a different set of care considerations that can mitigate insect concerns. Therefore, wool stands out as the material that poses the greatest risk for insect damage.
