What is Insect Netting?
Insect netting, also known as insect protection net or insect mesh, is a type of light physical barrier that is used to keep out pests.
It’s made from a variety of materials, including polyethylene， polyester, polyethylene, and nylon. Of these, polyethylene ones are the most common.
Insect nets and garden netting is available in a variety of different mesh sizes, from small (1mm) to large (5mm) and all of them have neat edges.
Garden netting is an extremely effective way to keep pests out of your greenhouse. It’s also much cheaper and easier to install than other pest control methods, like chemical insecticides.
why do you need it in your greenhouse?
Some farmers ask,
“Why do I need these nets? I have insecticide and that’s all I need?”
Insecticides kill insects, but they don’t prevent them from coming back. In fact, they can make the problem worse by killing off natural predators of pests like ladybugs and praying mantises. It’s a short-term solution that can lead to long-term problems.
By contrast, insect nets are a long-term solution to pest problems because they prevent pests from reaching their food source in the first place. They provide the same protection as an umbrella: by providing cover over your crops, they protect them from getting wet or damaged by wind gusts—and they keep out pests too!
Insect nets have many advantages that insecticides cannot replace.
Effective barrier blocks
If you have a problem with pests in your greenhouse, then the insect protection net is a must-have. It’s an extremely effective physical barrier that will keep out all sorts of pests to protect your crops, including aphids, whiteflies, and thrips.
Insect-proof net is also much cheaper and easier to install than other pest control methods, like chemical insecticides.
Prevent bacteria and viruses
By preventing insects from entering the greenhouse, we can effectively prevent many bacteria and viruses from affecting the greenhouse. This is because many insects spread these problems.
Backed by science, insect nets have been shown to be an extremely effective form of pest control in greenhouses.
In a study conducted by the University of California, Davis, insect netting was shown to reduce the number of whiteflies and thrips by up to 95%.
Reduce insecticide needed
The study also found that insect netting can significantly reduce the amount of insecticide needed to control other pests in a greenhouse.
And pesticides don’t just reduce plant yields, they also have an impact on the quality of the plants.
Insecticides can also have a harmful effect on humans ( the growers and the people who eat these plants). Many countries have laws that limit the use of pesticides in agriculture.
Increase plant yields and quality
Evidence-based research has shown that insect-proof netting can increase plant yields by up to 50%.
Other Benefits
Other than that, insect exclusion netting also provides a physical barrier against the wind and the sun. This can be extremely beneficial for young seedlings and delicate plants that are prone to damage from these elements.
How does insect netting work?
Insect netting works by physically blocking pests from entering the greenhouse. The tiny holes in the netting are too small for most insects to squeeze through, so they’re effectively kept out.
This physical barrier will also keep out larger pests, like birds and rodents.
Because of the use of the physical barrier feature, insect guard mesh is also commonly used in areas where chemical pesticides are not allowed or not desired to be used.
The insect screens control the invasion of pests and at the same time ensure ventilation of the indoor environment. By providing protection from wind and shade, insect screens also help to regulate the micro-environment in agricultural cultivation.
Insect-proof netting is an indispensable aid in agricultural growth.
How do you use insect-proof mesh?
Insect netting is very easy to use. Simply drape it over your greenhouse or cover the raised beds and secure it in place with insect-proof tape, staples, or weights. You can also put insect nets directly over your row cover or hoops. Make sure that the netting is taut so that pests can’t squeeze through any gaps.
When using it, we also need to make sure that all areas are covered. Because the pest is so small, even the tiniest gap can let them in.
To be extra safe, you can also add an insect-proof barrier around the ground or the base of the greenhouse.
You should also regularly check the pest netting for holes or tears and repair them immediately.
How to keep insect fabric from tearing?
The most common cause of insect netting tearing is physical damage. That’s why it’s important to handle the netting with care and avoid sharp objects that can puncture it.
Another way to prevent insect nets from tearing is to choose a high-quality product. Insect nets that’s made from durable materials, like polyethylene, are less likely to tear than cheaper options.
When you’re not using it, store insect mesh netting in a cool, dry place. And make sure to inspect it for holes and tears before each use.

How to choose?
There are so many products, how do I choose? Is there any basis for choosing?
Here we offer 2 options for you to choose from, so you can choose your insect screen according to your own situation.
1. Choice by the kinds of pests
If you want to keep out smaller pests, like thrips and whiteflies, you can use a smaller mesh size. For larger pests, like caterpillars and beetles, you’ll need a larger mesh size.
For example, the size of thrips is generally 2-3mm, and the size of the whitefly is 3-4mm, so the mesh size can be 1.8*1.8mm or 2.0*2.0mm.
As for the caterpillars, the common ones are 5-6mm, and the big ones can be more than 10mm, so the mesh size can be 3.0*3.0mm or 4.0*4.0mm.
For tiny insects, such as cabbage root flies, carrot flies, and leek moths, some extra small mesh insect screens are needed.
The insect netting EyouAgro provides has different mesh sizes and also can be customized according to your desired size and the width and length of the fabric of the anti-insect net.
