Netting for Raised Beds | Stop Pests Without Chemicals

Netting for raised beds blocks birds, insects, and wildlife from your crops while letting light and rain through, as long as you match the mesh size to the specific pest you’re excluding.

A single season of watching birds strip your blueberry bushes or cabbage moths lay eggs under every leaf is enough to convert anyone. Netting is the cleanest fix—no sprays, no traps, just a physical barrier that sits above your plants on a hoop frame. The trick is choosing the right mesh and installing it so nothing gets underneath.

Match the Mesh Size to the Pest

Birds and large animals need netting with holes smaller than 5 mm—roughly the size where you cannot fit a fingertip through. Anything larger and smaller birds will squeeze right in. For insect exclusion, the mesh must be fine enough to block the specific pest: cabbage moth, flea beetle, carrot rust fly. Too open a weave lets them pass; too fine and airflow drops. If you’re unsure, a garden mesh guide recommends checking which pests are currently active in your beds before buying anything—sealing a pest inside the netting makes the problem worse.

Build a Support Frame First

Netting must never rest directly on your plants. Crops need airflow overhead, and fabric touching foliage creates a bridge for pests and disease. The standard solution is a hoop frame: arches of poly pipe, conduit, bamboo, or flexible rods spaced every couple of feet along the bed. Bury the ends at least 300 mm into the soil for stability, or secure them with saddles fixed to the timber sides of the bed. One reliable method for an 80 cm wide bed uses three 260 cm poly-pipe pieces bent into hoops, with metal saddles screwed into the bed frame to hold them in place.

Another common approach uses 10 mm holes drilled into the bed sides, with 8 mm rods bent into arches and inserted into those holes. The key is that the frame stands securely in wind—loose hoops let the net sag onto plants and defeat the purpose. Our tested product roundup of garden netting for raised beds covers specific hoop kits that simplify this step if you want a ready-made system.

Install the Netting Tight and Secure

Once the frame is up, drape the netting over the hoops so it reaches the ground on all sides. Pull it taut—sagging netting catches wind, flaps, and lets animals push underneath. Fasten the perimeter with landscaping pins, plant clips, or pegs driven into the soil. At the ends of the bed, bunch the excess netting and tie it off with twine or secure it with a clip so there is no open gap. One deterrent left partly unscrewed into the bed frame forms a hook for tying down the net—simple and effective.

Leave enough overhang that you can lift one side for harvesting. The netting should stay in place most of the season except when you need to get in to prune, inspect, or pick. When you do open it, check for pests first before resealing.

What Type of Netting Works Best?

FAQs

Can I use bird netting for insects too?
No. Bird netting has holes too large to stop cabbage moths, flea beetles, and other small insects. You need a separate insect-exclusion mesh with much finer weave for those pests.

Will netting hurt my plants in hot weather?
Not if it’s installed on a hoop frame. The gap between netting and foliage preserves airflow. Fine insect mesh can trap heat, so shade cloth is a better choice for heat-sensitive crops during peak summer.

How do I stop netting from blowing off in wind?
Bury the hoop supports at least 300 mm deep, pull the netting taut, and pin every edge with landscaping staples or pegs. Bunched and tied ends also prevent the wind from getting under and lifting the whole cover.
