Insect covers provide an alternative pest control option for
growers. Insect covers come in different sizes and are suitable for control of
a whole host of insects such as carrot rust fly, cabbage maggot, and flea beetles.
Insect covers will create a physical barrier between the crop and flying
insects. It has to be applied tightly so insects are unable to get under the
netting.

Insect covers do not trap heat and therefore are used on
cole crops, carrots etc where extra heat might be undesirable. On the other
hand crops such as cucurbits, lettuce and peppers may benefit from extra heat, so floating
row covers are more beneficial.
