What should I pay attention to when using pest control nets?
Many pests start to move to the shed in autumn, especially some moths and butterfly pests, due to the large size of these pests, vegetable farmers can use relatively small number of mesh insect net,
such as 30-60 mesh insect net.
But for more weeds outside the shed, more whiteflies, according to the smaller size of whiteflies, to prevent them from entering through the eyes of the insect screen, it is recommended that farmers use a denser insect screen,
such as 40-60 purpose.
Color selection
For example, thrips have a strong tendency to blue, the use of blue insect screen is easy to attract thrips outside the shed to the shed around, once the insect screen is not covered tightly will make a large number of thrips into the shed to cause harm;
and the use of white insect screen, the shed will not occur this phenomenon,
and when used with shade net, to choose white is appropriate.
There is also a silver gray insect protection net has a better rejection of aphids, black insect protection net shade effect is significant, winter, continuous cloudy days are not suitable for use.
General spring and autumn compared to summer, the temperature is lower, the light is weaker, it is appropriate to choose white insect screen;
summer in order to take into account the shade, cooling, it is appropriate to choose black or silver gray insect screen;
in aphids and virus disease serious areas, in order to drive away aphids, prevent virus disease, it is appropriate to choose silver gray insect screen.
Insect netting is relatively easy to use, what should be noted in the process of use?

The two sides of the brick or soil pressure tightly.
Do not give pests the opportunity to invade, in order to achieve satisfactory insect control effect.
The general wind conditions can be used to press the net line.
In case of 5-6 grade wind, you need to pull on the pressure net line to prevent the net from being lifted by high wind.
②Choose the suitable specification
The specifications of insect-proof nets mainly include width, aperture, color and so on.
Especially the aperture, insect netting mesh is too small, the mesh is large, can not play the proper effect of insect control.
Too many mesh, small mesh, although insect-proof but will increase the cost of insect protection net.
