The use of monitoring traps is highly recommended for certain insects. These devices provide ongoing
coverage and are a must in spaces that are unseen or inaccessible. They include sticky traps and
pheromone traps among others.
Sticky Traps: Some insects are attracted to bright yellow, blue or other colors so they can be caught
on colored sheets of plastic or cardboard that is coated with glue. Sticky traps are commonly used as
a monitoring tool in greenhouses and orchards. By regularly checking the sticky traps, the initial
presence of a potentially damaging insect population can be detected.
