Bird netting vs insect netting: why the mesh decision changes
Bird netting and insect netting are both netting in the same way a bicycle and a delivery truck are both transport: the category is shared, almost nothing else is, and a request written for one of them rarely survives contact with the other.
In short
Bird netting usually uses larger openings and focuses on physical exclusion of birds from fruit or plants. Insect netting uses much smaller apertures and must balance pest exclusion with airflow. A quote request should state the target animal or pest first, then the crop, dimensions, installation and roll format.
What is the main difference?
Birds are large and insects are small, which sounds too obvious to be worth writing down until you follow it through the specification, where it moves every line:
- bird netting can often use larger mesh;
- insect netting may need apertures below 1 mm;
- bird netting usually has less airflow penalty;
- insect netting needs more careful climate thinking;
- installation tension and access needs differ.
If the buyer says “netting for berries”, the next question is whether the problem is birds, insects, sun or all three.
When does bird netting make sense?
Bird netting is a practical starting point for:
- berries;
- fruit trees;
- vineyards;
- small garden beds;
- crop areas where birds are the main loss.
The quote should include mesh size, material, UV treatment, dimensions and fixing method.
When does insect netting make sense?
Insect netting is the starting point when the target is thrips, aphids, whiteflies, leafminers or similar pests.
The key field is aperture in millimeters. Use the Mesh Size Visualizer, then review insect netting specifications.
What if you need both?
Sometimes a grower wants protection from birds and insects at once, and the reflex is to buy the finer of the two nets on the reasoning that it covers both problems. It does cover both, in the narrow sense that a fabric which stops thrips will certainly stop a blackbird, but it also brings the insect net’s airflow penalty to a block that only ever had a bird problem, along with its price per square meter and its weight on the structure, so the convenient decision quietly costs the crop ventilation it never needed to lose.
The honest rule is to specify the smallest target you genuinely need to stop, and to buy a second and coarser net for the rest when the two problems sit in different parts of the holding.

Frequently asked questions
What is the difference between bird netting and insect netting?
Bird netting usually uses larger openings and focuses on physically excluding birds from fruit or plants. Insect netting uses much smaller apertures and must balance pest exclusion with airflow. State the target animal or pest first, then the crop, dimensions and roll format.
Can one net stop both birds and insects?
Not automatically. A net fine enough for insects can be needlessly restrictive if birds are the real problem. The honest rule: specify the smallest target you truly need to stop.
What mesh aperture stops insects?
It depends on the pest. Insect netting may need apertures below 1 mm for small pests such as thrips, so the decisive field is aperture in millimeters against the target pest, not a generic mesh count.
