Among the insects that infest food, we have some species of moths which belong to the Lepidoptera order.
The development of this pesti s generally associated with food of vegetable origin, such as corn, flour, pasta, biscuits, spices and dried fruit.

The damage is mainly caused by the activity of larvae.
Even more than the “direct” damage caused, the “indirect” harmfulness is to be taken in highly consideration. This parasite can contaminate food by means of saliva. Sometimes this type of contamination is macroscopic, affecting the taste of food that needs to be discarded.

DAMAGES COMING FROM FOOD MOTH INFESTATION
The consequences of infestation may be relevant, consisting in irritation or allergic reactions caused by contact, inhalation or ingestion. Workers in storage house as well as consumers can be the potential victims.
The larvae can also cause damage to the packaging by piercing it with the mouthparts in order to reach the food substrate.
HOW TO MEASURE THE INFESTATION
The inspection of the environments and the foodstuffs can reveal traces of food moths and should allow the identification of infestation at an early stage, so as to take appropriate measures to prevent their progress.
Some of the indicators are:
Burrs silky (similar to silk) on food
Larval droppings (they usually appear as solid small masses, almost spherical, often light-colored and grouped together)
Traces left by the larvae during their journeys may be evident on dusty surfaces or for the presence of flour. These tracks will appear as linear or irregular grooves.
The glueboards based pheromone can be a good test to check the presence of moths. ATTENTION! This method attracts moths with pheromones. A long lasting use may attract new moths from the outside as well. For this reason they must be used only for short periods.
