Quick Answer: For most vegetable beds, Agfabric’s general-purpose garden netting (0.03” x 0.03” mesh, from about $11.64 for a 6.5x10ft piece) is the best all-around pick — it stops birds, squirrels, and larger pests like cabbage moths without the airflow penalty of a finer screen. If thrips or aphids are the actual problem, you need a genuinely finer mesh like Greenhouse Megastore’s 50-Mesh Anti-Insect Netting (from $1.99/ft, cut to length); if you’re protecting a raised bed and want hoops included, the ITOPFOX netting kit (about $79.14, 8.2x25.9ft coverage) bundles everything; and if birds are raiding a fruit tree, OGORI’s heavy-duty 3/4” bird netting (roughly $43.99-49.49) keeps birds out while still letting pollinators through.
Every crop guide and raised-bed article on this site mentions netting in passing — over hoops, over a trellis, draped across a bed — but the netting itself gets treated as an afterthought. That’s a mistake, because “greenhouse netting” actually covers at least three different products solving three different problems, and buying the wrong one wastes money twice: once on mesh that lets the actual pest through, and again on a replacement.
Greenhouse netting, by the numbers:
- 0.006 inch — the opening size needed to physically exclude thrips, per entomology research on greenhouse screening (summarized by Greenhouse Management and UConn IPM). Standard garden netting’s 0.03” mesh is five times too coarse to stop them.
- 30-40% — the airflow reduction a standard 50-mesh insect screen causes across a vent opening versus the same opening left bare, which is why screened vents typically need 40-60% more screen area to move the same amount of air.
- 3/4 inch (19mm) — the mesh size on heavy-duty bird netting like OGORI’s, deliberately coarse enough that pollinators still reach blossoms while birds can’t get at the fruit.

1. Agfabric Garden Netting — Best Overall
Agfabric Insect & Bird Barrier Netting
- 0.03" x 0.03" mesh (PE, UV-resistant) blocks birds, squirrels, cabbage moths, cucumber beetles, and other larger garden pests while still passing rain, air, and sunlight through.
- Sold in sizes from 6.5x10ft (about $11.64) up to 10x30ft ($26.97–$36.92), so you can match coverage to a single bed or a full hoop house without excess waste.
- Works directly over hoops, a trellis, or draped straight onto plants — no dedicated frame required.
- Won't stop thrips or aphids; the mesh opening is roughly five times too large for that job (see the fine-mesh pick below).
- Reusable season after season if stored dry — the main wear point is UV breakdown after several summers in direct sun.
This is the netting to buy first if you don’t know yet exactly which pest is the problem. It handles the majority of greenhouse and raised-bed pest pressure — birds pecking at seedlings, squirrels digging, moths laying eggs on brassicas — at a price point where covering a full bed costs less than one damaged crop. If you’re also fighting aphids, whiteflies, or spider mites specifically, pair this with the treatments in our greenhouse pest control guide rather than expecting the netting alone to solve it.
2. Greenhouse Megastore 50-Mesh Anti-Insect Netting — Best for Thrips & Aphids
Greenhouse Megastore Anti-Insect Netting, 50 Mesh
- 50-mesh HDPE screen with openings fine enough to physically exclude thrips, aphids, and whiteflies — not just larger insects.
- Sold by the linear foot and cut to order, in widths from 6.5ft up to 16.4ft, so you buy exactly the length a vent, door, or bed needs instead of a fixed roll size.
- Reduces airflow through a covered opening by roughly 30-40% versus bare ventilation — budget 40-60% more screen area than the vent opening itself to keep ventilation adequate.
- Best reserved for vents, doors, and bed covers where fine-pest exclusion actually matters, rather than draping over an entire structure where the airflow penalty adds up.

If thrips, aphids, or whiteflies are the actual pest — not birds or squirrels — this is the mesh to use, and general-purpose garden netting genuinely will not do the job. The trade-off is airflow: a 50-mesh screen over your main vents can choke ventilation on a hot day if you don’t oversize the screened area, so reserve it for targeted openings rather than wrapping an entire structure in it.
3. ITOPFOX Garden Mesh Netting Kit — Best All-in-One Kit for Raised Beds
ITOPFOX Garden Mesh Netting Kit with Steel Hoops & Clips
- Covers an 8.2 x 25.9ft footprint at 42.5" tall — sized for a long raised-bed run or a small hoop tunnel, not a single pot.
- Includes rustproof-coated steel hoops and 12 clips in the box, so there's no separate hoop or fastener purchase.
- Standard insect/bird mesh (not ultra-fine) — keeps out birds, rodents, and larger insects while still passing sunlight, air, and water through to the bed.
- A direct fit for this site's own raised-bed hoop retrofit approach — one kit replaces separately sourcing hoops, clips, and netting.
If you’re starting from an empty raised bed with no hoops yet, this is the faster and often cheaper path than buying hoops, netting, and clips as three separate line items. The hoops double as a light frost-cover frame in shoulder season too, matching the retrofit approach covered in our raised-bed guide — one hardware set, multiple coverings through the year.
4. OGORI Heavy-Duty Bird Netting — Best for Fruit Trees
OGORI Heavy-Duty Nylon Bird Netting, 25x100ft
- 3/4" (19mm) mesh — intentionally coarse. It's sized to stop birds, not insects, so pollinators can still reach blossoms on a flowering tree underneath.
- Commercial-grade nylon holds up to repeated seasonal draping and removal over a citrus, avocado, or grape vine canopy better than lightweight garden netting.
- 25x100ft covers a mature fruit tree or several smaller ones from a single roll, with enough slack to drape rather than stretch tight.
- Pairs with this site's fruit-tree guides — our greenhouse avocado tree and greenhouse citrus guides both cover pollination timing that a too-fine mesh would block entirely.
Don’t reach for fine insect mesh on a fruit tree in flower — a 0.03” or 50-mesh screen keeps bees out along with birds, which can wreck fruit set on a tree that needs pollinator visits. Coarse bird-specific netting like this is the right trade-off: it accepts that insects (helpful ones included) still get through, in exchange for actually stopping the birds that would otherwise strip the crop before harvest.
How to choose greenhouse netting
- Identify the actual pest before buying mesh. Birds and squirrels need only a basic 0.03” barrier; thrips and aphids need a genuinely fine 50-mesh screen; a flowering fruit tree needs coarse mesh that still lets pollinators through. These aren’t interchangeable — the wrong choice either fails to exclude the pest or blocks pollination.
- Don’t screen more area than necessary with fine mesh. The airflow penalty on 50-mesh netting is real (30-40% per our stats above); use it on vents and problem beds, not as a blanket cover for an entire structure.
- Buy a kit if you have no hoops yet, a roll if you do. Kits like ITOPFOX save a separate hoop and clip purchase; a plain roll of Agfabric is cheaper if your raised bed or hoop house already has a frame.
- Match attachment hardware to the job. Our greenhouse clips guide covers the stainless and ABS clips that hold any of these nettings onto hoops or frame tubing.
- Check what’s bundled before adding more. Kit products already include clips and sometimes hoops — confirm what’s in the box before buying fasteners separately.
The bottom line
Start with Agfabric’s general-purpose netting for everyday bird, squirrel, and larger-insect protection — it’s the right default for most vegetable beds and greenhouse vents. If thrips or aphids are specifically the problem, step up to Greenhouse Megastore’s 50-mesh screen on the openings that need it, accepting the airflow trade-off. Starting a raised bed from scratch, ITOPFOX’s kit bundles hoops and clips so there’s nothing else to source. And for a fruit tree in flower, reach for OGORI’s coarse bird netting, not a fine insect screen — pollinators need to get in even while birds stay out. Whatever you pick, see our greenhouse clips guide for the fasteners to hold it in place.
