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. The specification is not.
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. Insects are small. That sounds obvious, but it changes everything:
- 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 millimetres. Use the Mesh Size Visualizer, then review insect netting specifications.
What if you need both?
Sometimes a grower wants protection from birds and insects. That does not automatically mean one net should do both jobs. A net fine enough for insects may be unnecessarily restrictive if birds are the real problem.
The honest rule: specify the smallest target you truly need to stop.

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 millimetres against the target pest, not a generic mesh count.
