Inspection simply means to take a close look. Take a close look at any items that might be subject to insect infestations. Stored product insects can also infest nonfood products such as dried flowers. All such items should be inspected. A thorough inspection of the storage areas should also be completed because hidden infestations could be found in those areas.
Monitoring is the third way to prevent and locate outbreaks.
By the use of monitoring, one can find an infestation as it begins and can get control of it before it becomes a severe problem. The most effective method is to use both in combination. Pheromone traps are species specific and must be chosen according to the target insect. Blunder traps are good in that although they do not target a specific insect, they can give a sampling of all insects in the area. This is particularly useful for insects for which there is no pheromone trap.
