Insect Netting

Keeping the good in and keeping the bad out.

Insect netting is a straightforward solution to a globally recognized problem. As the name indicates, it is designed to keep harmful insects out of your greenhouse and keeping useful insects and bees inside by applying a netting system in the ventilation windows. The meshes are available with different sizes of openings and can thus be installed to keep out specific species.

Insect Netting System

There are two types of insect netting, integrated or added on with a cassette. In the design stage, choosing for integration options in the aluminium system, even-though not used, allows for quick installation afterwards during remodelling, reselling, re-purposing or anticipating on new unwanted pests.

Integrated insect netting

In the integrated system, the aluminum profiles in the ventilation windows are designed to house insect netting. Simply installing ventilation windows therefore gives all the provisions required to install insect netting / mesh. This is the most future-proof system, with the smallest light interception. Regardless of the current needs, DutchGreenhouses® ensures this is always integrated to be prepared for future changes.

Cassette system

The cassette system is mounted on the ventilation window afterwards. The aluminum cassettes are custom-made to fit the ventilation window and they are immediately equipped with insect mesh. DutchGreenhouses® offers an integrated or cassette system with UV-stabilized meshes and is then mounted directly onto the ventilation windows as a whole. This system is particularly suitable for existing Venlo greenhouses, but also works well for wide-span greenhouses.

Mesh Sizes

Depending on the IPM strategy and the presence of unwanted pests outside the greenhouse, the insect netting can be selected. A smaller mesh-opening does not only create a barrier for insects, but also reduces ventilation capacity. This must always be kept in mind when designing a greenhouse. The below table lists the most commonly applied mesh sizes and pests that are to be kept out.

0,15	x	0,35	mm	Thrips
0,4	x	0,45	mm	Small white fly
0,4	x	0,7	mm	White fly (mostly applied)
0,6	x	0,6	mm	Lice
0,8	x	0,8	mm	Mine Fly, Weevil
1,35	x	1,35	cm	Cabbage Root Fly
1,0	x	1,5	cm	Bees

Integrated Pest Management

Integrated Pest Management (IPM) is a holistic approach to pest control in greenhouses that emphasizes long-term prevention through a combination of techniques such as biological control, habitat manipulation, and modification of cultural practices. This not only helps to reduce the use of chemical pesticides, which can be harmful to both the plants and the environment, but also promotes a more sustainable form of agriculture.

One of the crucial components of an effective IPM strategy in greenhouses, is the use of insect netting. Insect netting acts as a physical barrier to prevent the entry of various pests like whiteflies, aphids, and thrips, thereby reducing the need for chemical interventions. These nets are usually made from materials that allow light and water to pass through, ensuring that the plants receive the essential elements they need for growth. Besides serving the immediate function of pest exclusion, insect netting also helps in the broader IPM strategy by enabling the introduction of biological controls, such as beneficial insects, that can naturally manage pest populations within the greenhouse. Insect netting, or at least the preparation for it, plays a critical role in creating a balanced, sustainable ecosystem inside the greenhouse.

FAQ

What is the difference between an integrated insect netting system and a cassette system?

Integrated insect netting systems are generally built into the structure of new greenhouses and offer minimal light interception, while cassette systems are more used to add-on during retrofitting, upgrade or simply as an afterthought.

Should I choose insect netting in my new greenhouse?

Yes, at least the provisions for a later install. To create a future-proof greenhouse, where you have your Integrated Pest Management under control, insect netting is a must.

What type of mesh opening do I need?

The mesh opening size greatly depends on the presence of pests in the area of the greenhouse. Your IPM strategy must also be considered when choosing the mesh opening. The below table contains the most common pests and mesh sizes applied in greenhouses:

0,15	x	0,35	mm	Thrips
0,4	x	0,45	mm	Small white fly
0,4	x	0,7	mm	White fly (mostly applied)
0,6	x	0,6	mm	Lice
0,8	x	0,8	mm	Mine Fly, Weevil
1,35	x	1,35	cm	Cabbage Root Fly
1,0	x	1,5	cm	Bees
