Pests & plant health
Fit insect mesh and wildlife-safer crop netting
Choose mesh for the actual pest.
When to do it
Before pests reach the crop; allow for pollination at flowering.
What you need
- Mesh appropriate to the target pest
- Stable frame
- Secure edge fixings
How to do it
- Choose mesh for the actual pest. Bird netting may not exclude insects. For household crop netting, use openings no larger than 5 mm by 5 mm at full stretch as a wildlife-safer baseline and check your local rules; this limit is mandatory in Victoria.
- Inspect plants first so you do not enclose an existing infestation.
- Fit netting taut over a frame clear of foliage, with no loose loops. Secure edges and provide an opening you can close after harvest or watering.
- Plan pollination: uncover flowers when insect access is required, or use a suitable hand-pollination method. Re-secure afterwards.
- Check daily for damage or trapped animals. Contact a wildlife rescuer for entanglements; never handle a bat. Remove and securely store unwanted netting.
What success looks like
- The crop is enclosed without gaps or loose entangling folds.
Watch out for
- Draping large loose mesh over fruit.
- Forgetting pollinators or letting plants press against insect mesh.

Check that pollination is the likely issue.
Check a crop’s pollination needs
Identify the crop and cultivar: self-fertile, self-incompatible, separate male and female plants, and seedless fruiting types have different needs.
