We chose to offer LS Insect Screens because they perform as advertised and are they are the creative fabric company of the industry worldwide. Our largest market is for greenhouse screens, LS Svensson greenhouse insect screens/fabrics. Insect screen is also known as thrip screen, insect fabric, white fly screen, and insect nets.

A new insect screen has been developed for whitefly exclusion and high airflow, called LS Econet 4045 Max. It has holes of .40 x .45 mm, allowing 96% direct light transmission and only 25% air reduction.

Some shade net fabrics can be used for large insects and bugs.

For whitefly insect control as well as aphids, insect fabric we must also consider reduced air flow. The thrip screen is the most dense insect protection product and very effective but reduces air flow more than any other screen or fabric.

Most insect screens are plastic/polyester and come in various light covers and can be cut, sewn and sized to your greenhouse and agricultural needs.

Minimum order is $350 to $500 depending upon quantity, type and dimensions. Large orders available from various international warehouses. Not appropriate fro retail use.

LS Econet Greenhouse and nursery screens carry a warranty against UV degradation: 3 years for outdoor use and 5 years for indoor use. Longevity in most climates is 5 to 8 years. Some greenhouse screens have lasted as long as 10 years.

Excluding pests from growing areas is the most effective control method. Some growers have reduced their pesticide use by 90% using LS ECONET in combination with insect-free stock and good sanitation. In addition to being the most effective, it is also the least expensive form of prevention.

Plan your greenhouse crop production and IPM program in advance. Using good sanitation and exclusion is the key to properly managing your growing environment. Design your ventilation system to handle the pressure loss form insect screens.

Here are some helpful tips for excluding insects from your greenhouse:

  • LS ECONET generally must have openings as small or smaller than the insects it excludes.
  • Any LS ECONET will reduce the number of insects migrating into crops.
  • LS ECONET must be sized appropriately to avoid hampering ventilation.
  • Use LS ECONET to screen vents and doorways.
  • Keep doors closed, except when entering or leaving the greenhouse.
  • Construct a screened vestibule at greenhouse entrances. Workers and equipment must pass through a plant-free space between
    two sets of doors before entering the growing area.
  • Create a positive pressure entrance by installing fans so that they blow into the space between the doors causing air to
    flow from inside to outside.
  • LS ECONET must be cleaned periodically. Use a stream of water to wash from inside to out.

LS ECONET screens are woven from UV stabilized acrylic and HDPE yarn. These materials are warranted for a long working life even when used outside. All LS ECONET screens are a translucent white in color. Various types of Econet have rectangular openings rather than square. The advantage is that rectangular openings have more open area than square openings and result in better ventilation. Warranties up to 5 years are available if the Econet is properly installed and maintained. Other widths, cutting and sewing available upon request.
We offer insect screens from other sources in Europe/Asia and other factories worldwide.
