A single cabbage moth can lay over a hundred eggs on your brassicas in one afternoon, and you won’t spot a single one until the leaves turn to lace. That’s the moment most gardeners discover insect netting covers—usually too late for that crop, but just in time for the next one.
The good news: netting is one of the few pest controls that works without sprays, timing, or guesswork. Pick the right mesh, secure it properly, and pests simply can’t reach your plants.
Get the mesh size, frame, and installation wrong, though, and you’ll trap heat, block pollinators, or watch the whole thing collapse in a windstorm. Here’s how to get it right the first time.

Key Takeaways
- Match your mesh size to your worst pest threat—0.6mm stops thrips, 1.0mm blocks root flies, 1.35mm handles moths, and 2.0mm keeps out bigger critters like rabbits and birds.
- Build sturdy PVC hoop frames with proper clearance for mature plants, then bury the netting edges 6-12 inches deep to stop pests from sneaking in underneath.
- Since fine mesh keeps bees out too, you’ll need to lift the netting during bloom time so squash, cucumbers, and other pollinator-dependent plants can still set fruit.
- Weekly checks for tears and gaps, along with end-of-season washing and dry, dark storage, will keep your netting working well for years instead of falling apart after one season.
Choose Mesh Size for Target Pests
Not all mesh is created equal, and picking the wrong size is like locking your front door but leaving a window wide open. The hole dimensions decide exactly which pests get turned away and which slip right through. Here’s how the sizes break down, from the tiniest thrips to the toughest rabbit.

0.6mm Mesh for Tiny Insects
Thrips and whiteflies are tiny enough to slip through screens that stop bigger bugs — 0.6mm micromesh is your answer. It blocks these pests while still letting 75-85% light transmission through.
If frost is also a concern for your seedlings, pairing that fine mesh with cold weather cloches for beginner gardeners can keep young plants protected through unpredictable spring temperature swings.
- Blocks thrips, whiteflies, no-see-ums
- Preserves airflow, limits humidity pockets
- UV-stabilized fabric resists sun damage
Expect minor airflow restriction and a slight microclimate temperature rise underneath.
For effective insect protection, understanding mesh size measurement systems is essential when selecting the right screen density. mesh size measurement systems
1.0mm Mesh for Root Flies
Bump the mesh up to 1.0mm and you’ve got a physical barrier against root flies — cabbage root fly, carrot rust fly, the underground egg-layers.
| Mesh | Blocks | Light |
|---|---|---|
| 0.6mm | Thrips | 80% |
| 1.0mm | Root flies | 85%+ |
| 1.35mm | Moths | — |
Bury edges 5cm deep; gaps invite trouble.
1.35mm Mesh for Moths
Cabbage moths and their kin need a finer barrier — that’s where 1.35mm mesh comes in, built for moth egg prevention on brassicas.
It still allows solid light transmission and airflow optimization, so plants won’t overheat. Choose UV-stabilized mesh for durability against sun breakdown. This size delivers strong pest exclusion effectiveness while keeping your insect netting breathable, outperforming any basic floating row cover.
2.0mm Mesh for Larger Pests
Grasshoppers, beetles, even nosy birds and rabbits — that’s the job for 2.0mm mesh, stepping up where finer netting isn’t needed.
- Blocks larger pests without smothering airflow
- Stainless steel or polymerized fiber resist weathering
- Woven, uniform openings keep pest exclusion efficiency consistent
- Edge sealing methods stop gaps pests exploit
- Works for multiple seasons with proper mesh durability
It’s the workhorse size for open beds facing bigger trouble.
Balance Airflow, Light, and Protection
Here’s the tradeoff nobody mentions upfront: finer mesh means better pest exclusion but weaker airflow management and light transmission.
| Mesh Size | Tradeoff |
|---|---|
| 0.6mm | Best pest block, least airflow |
| 1.35mm | Balanced protection |
| 2.0mm | Best airflow, least fine-pest control |
Choose UV stabilized mesh matching your worst pest threat, not the finest option available — your plants need that airflow-light balance too.
Measure Beds and Build Supports
Picking the right mesh is only half the job. Now you need a frame that holds it up properly, keeps it off your plants, and fits the bed you’ve actually got. Here’s how to measure, choose your support style, and get everything built to last.
If you’re growing squash or cucumbers, remember to pull the mesh back during their brief daily pollination window, or better yet, pair your frame with natural pest control methods that don’t block pollinators.
Calculate Netting Size and Allowance
Guessing your netting size wastes money and leaves gaps for pests. Measure length and width of each raised bed, then add allowance:
- 5% for calm, small beds
- 10% for irregular shapes or hoop-wrapped nets
- 10-15% in windy spots
- 5% for canopy growth
- Round up to the nearest foot
That overlap and tension allowance stops shortfalls before they start.
Choose Hoops or Floating Covers
Before you buy anything, decide: hoops or a floating row cover? Floating covers rest right on plants, quick to lay down but prone to chafing in wind.
A supported tunnel built on PVC pipe frames resists wind uplift, keeps foliage clear for garden bed access, and lasts longer—worth the extra setup time for durability.
Size Frames for Mature Plants
A frame sized too tight chokes your plants before pests even show up. Plan for mature canopy width plus 20-30% clearance—sprawling squash or cucumbers need 4-6 foot diameter hoops, while tomatoes and peppers want 5-6 feet of frame height for vertical growth.
Space frames to match mature plant spacing, and expect to adjust hoop height seasonally as growth accelerates.
Build Stable PVC Hoops
Wobbly hoops mean sagging netting, and sagging netting means pests find a way in. Use 1-inch schedule 40 PVC for main hoops, spaced every 3-4 feet, with 2-3 cross braces per 8-foot span.
Bury ends 6 inches deep or anchor with stakes. Cement PVC connectors for permanent joints; use snap clips if you’ll disassemble often. Preassemble flat first to check alignment.
Customize Irregular Garden Beds
Curved beds throw a wrench in standard PVC hoops, so bend flexible irrigation tubing to follow the contour instead. Mark the outline with a hose first, then measure garden bed dimensions at the widest points for netting allowance.
Use rot-resistant cedar edging where soil meets the supported tunnel, keep 18-inch paths for access, and rotate crops each season to protect soil health.
Install Insect Netting Step-by-Step
With your beds measured and hoops standing firm, it’s time for the main event. This is where careful hands make all the difference between a snug, pest-proof cover and a flappy mess that lets bugs waltz right in.
Here’s exactly how to cut, drape, and secure your netting so it stays put through wind, rain, and everything else the season throws at it.
Cut Netting Without Fraying
Cut slow and steady with sharp fabric scissors, following a marked chalk line, to keep edges crisp.
For UV-stabilized mesh or polypropylene, a hot knife seals as it cuts, fusing fibers instantly. No hot knife? Trim excess, then run a heated edge sealer along the line. Let it cool fully before handling—rushing invites fraying and re-melting.
Drape Netting Over Supports
With clean edges cut, lay netting over your garden hoops so it rests on top, draping evenly down each side—extend it slightly beyond hoops for secure edge sealing.
Guide it over curves gently, keeping frame tension balance even.
- Center netting fully
- Check overlap on ends
- Ease down each hoop
- Leave a liftable flap
Clip Netting Firmly in Place
Once netting’s draped, grab your garden clips and start at the corners—this locks a taut perimeter before you tackle the sides.
Space clips every 15-20 inches, using smooth-jawed, weather-resistant clips that won’t snag UV-stabilized mesh.
Adjust tension as you go, and give it a quick wind resistance test—flutter means loose clips.
Seal Every Edge and Corner
Clips hold the top taut, but bugs sneak in low.
Bury the bottom edge 6-12 inches deep, or run a soil burial method along stakes.
Add reinforced patches at corners, your weakest leak points, and leave one flap loose as an access point for weeding.
Reinforce Covers Against Wind
Gusts are the real enemy here, not bugs. Space hoops 1 to 1.2 meters apart, stake them firmly, and keep tops rounded so wind slides off instead of tearing mesh.
Add weighted side ballast—bricks, water jugs—along the soil burial method line.
Check garden staples and tension weekly; loosen slightly in calm spells, tighten before storms roll through.
Maintain Covers Through Every Season
Getting your netting installed is only half the job done. Keeping it working well through a whole growing season takes a bit of ongoing attention, from watching for gaps to knowing when to store it away. Here’s what you need to check and do along the way.
Manage Pollination Under Netting
Bees can’t visit blossoms through fine mesh, so squash and cucumbers may set no fruit at all without help. Lift the ends during bloom to open pollination windows, then reseal after visits. Watch flowers daily for pollen deposits, and coordinate with local beekeepers on timing.
Companion planting nearby draws pollinators closer once you open the covers.
Monitor Heat and Plant Growth
Rarely do beginners realize how fast a tunnel can turn into an oven. Track canopy temperature with an infrared read, aimed downward at leaves, and set heat stress alerts if readings climb 2-5°C above air temp.
Watch growth rate daily; slowed leaves signal poor airflow circulation, meaning it’s time to vent and restore microclimate control.
Check Tears and Pest Gaps
A single 2cm gap is all a flea beetle needs to move in.
Walk your tunnel weekly:
- Inspect edge tears near seams
- Check gap size at overlaps
- Examine fixation points and clips
- Evaluate light flow for hidden tears
- Review seasonal checks after storms
Keep a patch kit handy—thorough netting inspection now beats replanting later.
Clean and Repair Netting
End of season? Time to wash, not just fold and forget. Wash netting in mild soap and lukewarm water, rinse fully, then check for damage while it’s still wet—tears show up easier against light.
Patch small tears from the inside with matching mesh and a whip stitch. Grab your patch kit, dry completely before storage, and your UV-stabilized mesh will outlast the guesswork.
Store Covers Away From Sunlight
Sunlight is the enemy once mesh comes off the hoops. UV degradation breaks down fibers fast, so pick a cool dry place, avoid heat sources like garages near appliances, and skip clear bins.
Breathable storage bags beat sealed plastic for airflow. Label storage containers by size.
That small habit protects your long-term investment, keeps UV-stabilized mesh strong, and cuts waste reduction costs next season.
Top 6 Insect Cover Products Compared
Knowing the mesh math and hoop-building basics only gets you halfway there, you still need to pick actual products off the shelf.

Frequently Asked Questions (FAQs)
What are the alternatives to insect netting?
No mesh handy? Try floating row covers, fruit cages with welded mesh, or burlap toppers. Reflective mulches and companion planting also confuse pests behaviorally, while beneficial nematodes and crop rotation tackle soil-dwelling troublemakers without a single yard of fabric.
What size mesh is best for insect netting?
Honestly, there’s no single magic number that stops every bug on earth. Your best bet: 6mm to 0mm mesh experiences thrips, aphids, and root flies, while staying loose enough to keep airflow and light where your plants need them.
Does rain go through insect netting?
Yes, rain passes right through. Mesh between 97mm and 5mm lets water reach your soil while blocking pests. Light rain just dampens the surface; heavy downpours soak through since standard netting never fully blocks water flow.
How to attach insect netting?
Picture netting billowing loose in the wind, tearing at the seams. Stop that by clipping netting to hoops every 6-12 inches with zip ties, then burying edges 1-2 inches into soil for a pest-tight seal.
Does insect netting work against slugs or snails?
It works, provided you seal every edge tight to the soil. Fine mesh blocks their mouthparts, and a continuous barrier stops crawling entry—though it won’t kill them, just keeps them off your seedlings.
Can netting be used on fruit trees too?
Trees don’t read the rulebook that says netting is only for veggie beds. Build a frame clearing branches by 30cm, space hoops 5-5 meters apart, and drape netting for solid bird and insect protection.
Does netting protect plants during hailstorms or heavy rain?
Insect mesh isn’t rated for hail, but a taut, well-anchored cover still absorbs impact, protects foliage from bruising, and blocks wind-driven rain from shredding leaves—so it’s a decent backup shield, not a true hail net.
Can netting be left on year-round without removal?
Yes, but it’s not maintenance-free. UV-resistant netting can stay put multiple seasons if you inspect monthly, watch for sagging that traps moisture, and mind snow or wind load—otherwise you risk fungal disease and torn seals.
Conclusion
An ounce of prevention beats a pound of cure, and that’s the whole philosophy behind netting your beds.
Master insect netting covers for beginners, and you trade seasonal panic for quiet confidence: the right mesh, taut edges, and sturdy hoops do the job sprays never could.
Check your covers weekly, patch small tears before they become highways for pests, and your brassicas will grow lace-free, untouched, and entirely yours.
