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 in 28 years 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.”
