Best Insect Netting for Plants of 2026

Sixty-five square feet is the honest headline, and for plenty of gardeners that is exactly the right amount: one 4 x 8 bed with enough overhang to bury the edges, or two smaller frames. This is the sheet we keep for that job, because a piece this size goes on in a couple of minutes instead of turning into an afternoon of dragging ten-foot-wide netting across a plot.

The mesh is listed at 0.03 x 0.03 inch, roughly 0.76 mm, and that number does the work — cabbage white butterflies, flea beetles and Japanese beetles all meet a barrier before they reach a leaf. What impressed us beyond the figure is the construction: the weave holds its shape, the edge stays neat, and the sheet goes on straight instead of snagging on every stake in reach. Sun and rain pass through, so watering does not mean lifting it off.

HDPE in a fine weave is also the combination that survives being folded and put away. Dry it, fold it flat, and it takes up the corner of a shed until spring. The limitation is simply scale: on a garden bigger than a couple of beds you will be buying two or three and joining them, and a join is where a moth gets through. Buy one sheet that covers the bed rather than patching coverage together.

When the beds run end to end along a fence, joining sheets is where the job turns ugly: overlaps flap, seams open, and the whole thing looks like laundry. Ten by fifty feet is the answer — 500 square feet in one piece, one length down the run, cut where you need it and no seam for a moth to find.

The mesh is 0.8 x 0.8 mm, square rather than oblong, and in practice that is the same class of protection as the 0.8 x 1 mm sheets here: it stops the moths, beetles and flies that do the visible damage and lets rain through. What struck us is how easy it is to see through, which matters more than it sounds when you are walking the plot every evening and do not want to lift the cover to check a crop.

It is light for its size, and that cuts both ways: easy to throw over a frame, easy for wind to shift. The thing to guard against is snagging. This weave catches on stake tops, rough sawn timber and rose thorns, and a snag becomes a hole. Cap your stakes, run a hand along the top edge of a homemade frame, and leave slack rather than pulling the sheet tight — do that and it is a cover you will get several seasons from.

Four feet wide by twenty-five long is a strip, and the shape is the whole point. It matches a standard raised bed or a single row under low hoops, with just enough overhang to weigh the edges down. Expect it to cover a whole plot and you will be disappointed; buy it for a row of kale and it is almost exactly right.

The weave is 0.8 x 1 mm, the oblong hole most of this group uses, and it is a sensible compromise for greens: fine enough to stop cabbage white and carrot fly, open enough that air moves through and water goes straight in. Jevrench says the PE is twice as thick as ordinary netting, and it does feel more substantial than the very thinnest sheets here — it stretches over hoops without splitting at the corners.

Width is where it gives ground. Four feet is fixed, so a wider bed needs two lengths side by side, and the seam between them is the one spot a butterfly will find. Because it is long and light, a gust lifts it along its whole length unless you peg or weight every few feet; we use a brick at each stride and that holds it. As a dedicated row cover it does the job well; as the only sheet you own, it is too narrow.

Two ten-by-thirty-three-foot sheets in one pack behave differently from one big piece. You can cut into one and keep the other whole, run one over this season's bed and hold the second for a late sowing, or cover two beds at opposite ends of the garden without a join between them.

The mesh is listed at 0.04 inch, about a millimetre, so this is standard netting rather than ultra-fine. It stops the big fliers — cabbage whites, beetles — and it does the bird job as well, which is why a sheet like this usually ends up over blueberries and cherries rather than over cabbage.

Two things to check before it goes on. The edges are cut rather than sealed, so they shed strands, and a loose strand on the ground is a hazard to birds; trim the edges before you lay it out. And unroll the whole sheet and hold it up to the light first, because the weave can arrive with gaps in it, and a gap you spot in September is one a moth found in June.

None of that is fatal, and the spare sheet is why this one keeps its place: a bad cut or a tear on a stake does not end the season, you just go to the second piece. For a plot with several beds and a bird problem alongside the insect one, the two-pack earns its keep. Keep the spare dry and folded, because sun is what kills a stored sheet left hanging on a shed wall.

Sold as insect netting, this one earns its place on the four-legged and feathered side of the ledger. Eight by ten feet suits a shrub, a small bed or a young tree, and the 0.7 x 0.8 mm mesh is fine enough for cabbage whites as well — but the sheet is very thin, and that is the trade.

Where it works is against things that push rather than crawl: rabbits, deer and birds. It drapes over a frame or a bush without weighing branches down, and the PE is UV-stabilised for a cover that stays out all season. Anchor it properly, though. This is the lightest-feeling sheet here, and a deer will push a loose edge aside without noticing it was there.

Toughness is the drawback. It snags on rough ground and on its own stakes, and once there is a hole a rabbit will find it; on an exposed site the wind works at the edges until they tear. Use it where the pressure is moderate — a suburban back garden, a shrub you are bringing through its first year — and put real weight or pegs along the edges rather than a few stones at the corners.

SnugNiture lists a 0.1 x 0.1 mm opening — far and away the finest mesh in this group — and that number changes the list of pests it stops. Thrips, whitefly and leafminer, the ones that walk through ordinary netting, have a much harder time reaching a crop under this sheet.

Handling is where the fineness shows. The sheet weighs about 1.2 pounds over ten by thirty-three feet, light enough to hang on hoops without bowing them, but the weave is thin and a stake top will punch through it. This is a cover to put up once at the start of the season, tie off and leave, rather than something to lift every morning to weed.

For a crop under real pressure from small sap-sucking insects, the trade is worth making: you give up some airflow and some light in exchange for a barrier the smallest pests cannot walk through. Where the problem is cabbage white or beetles, you are paying that cost for protection you do not need, and one of the standard-mesh sheets here does the job with more air around the leaves. Match the mesh to what is actually eating the crop.

This is the cheapest way into the category, and at 4 x 10 feet it is also the smallest sheet here: one bed, a strawberry patch, or a couple of containers under a frame. Four by ten covers a 4 x 4 bed with about a foot of overhang on each side, and not much beyond that.

The mesh is 0.8 x 1 mm, the same oblong weave the mid-priced sheets use, so on the pests that do the damage — cabbage white, carrot fly, flea beetle — it is doing the same work for less money. It is light, it drapes, rain and sun go through it, and it cuts to size with a decent pair of scissors.

What you give up is margin. There is no spare width to pull over a crop that grows taller than you planned, and the sheet is finished plainly, so a careless cut will run. Multi-season durability is the open question: the material is thin, the sheet is best treated as a season's cover, and a second summer out of it is a bonus rather than the plan.

For a first season, a single bed, or a trial against a pest you are not sure about, buy two and treat them as one season's worth of cover. It is the low-risk way to find out whether netting solves your problem before you commit to a sheet big enough for the whole plot.
