Practical Guides & Hands-On Tutorials

In high-value greenhouse and net-house projects we’ve supported, most “mesh failures” were actually installation leaks—especially at bottom edges, doors, and fan/vent frames.

From a technical support perspective, air-tight installation means continuous bottom sealing, profile + wiggle wire fixing, and a double-door vestibule to control airflow-driven entry.

In the greenhouse and net-house systems we’ve supported, airflow loss is often caused by dirty nets—not the mesh itself.

From a technical support perspective, the biggest avoidable mistake is bleach: it can brittle the yarn, weaken tensile strength, and permanently deform apertures.

This guide shows a safe step-by-step cleaning method, what to avoid, and how to inspect, repair, and store nets to extend service life.

The single most useful thing I’ve learned selling insect netting is this: mesh count is a marketing label, not an engineering spec. Two “40-mesh” nets from different mills can have aperture sizes 30%+ apart—which is the difference between blocking whiteflies and letting them through. That’s why every technical conversation we have with a new customer starts the same way: “What’s the target pest’s thorax width?”—because thorax width is the one body dimension insects can’t compress.

This guide gives you the thorax-width reference table for major pests, the aperture formula (mesh count + yarn diameter), and the decision flowchart that replaces “pick the finest mesh you can afford” with “pick the right mesh for your specific pest.”
