Which material is often used for tents to deter arthropods?

Nylon is often used for tents to deter arthropods due to its lightweight and durable nature. This synthetic material can be treated with insect repellent compounds, which can effectively keep insects and other arthropods at bay. The tight weave of nylon also helps prevent arthropods from penetrating the fabric, making it a suitable choice for camping and outdoor activities where insects can be a nuisance.

In comparison, while canvas is a strong and traditional material for tents, it does not inherently possess properties that deter insects, especially if untreated. Plastic may offer some resistance but is typically less breathable and not as durable for outdoor conditions. Metal, although it can provide structure for a tent, is not used as the material for the tent fabric itself and does not fulfill the role of deterrent against insects. Thus, nylon stands out as the most effective choice for reducing arthropod presence in outdoor tents.
