What Mesh Size Insect Netting Stops Aphids?

For most greenhouse vegetables, 40 mesh insect netting is ideal for controlling aphids while still allowing for air circulation.

Aphids are well known as one of the most common pests in greenhouses, damaging vegetables and seedlings and reducing yields. Using 40 mesh insect netting not only prevents aphids from entering the greenhouse but also avoids the need for pesticides.

If your crops are also susceptible to small insects such as thrips, 50 mesh insect netting is recommended for protection.

Is 40 Mesh Enough to Stop Aphids?

Yes. High quality 40 mesh insect netting can effectively block aphids, whiteflies, and many other common greenhouse pests, while still allowing for sunlight and air circulation.

Should I Choose 40 Mesh or 50 Mesh?

If your primary concern is aphids, 40 mesh insect netting is the best choice because it also allows for ventilation.

However, if your greenhouse is suffering from a severe thrips infestation, 50 mesh insect netting will provide better protection.
