Species Status of Angoumois grain moth
It has a nearly global distribution today, including essentially all of Europe as well as such far-flung places.
Life Cycle of Angoumois grain moth
Egg The egg of angoumois grain moth is small, often ovular, and can range in color but is generally inconspicuous. Secured to a substrate, it is a dormant stage where initial development begins internally, leading to the formation of the larva.
Larva As larvae, angoumois grain moth exhibit worm-like bodies with distinct head capsules. They lack fully developed wings, often have chewing mouthparts for feeding, and their primary function is growth, which involves multiple molts and size increases.
Pupal The pupa of angoumois grain moth serves as a transitional stage enclosed in a chrysalis. Within, the larval form undergoes major transformations, reorganizing into an adult. This stage varies in color and may blend with the surroundings.
Adult Emerging from the pupa, the adult angoumois grain moth’s development is marked by the presence of wings and functional reproductive organs. The body is fully formed and hardened, and the adult is mobile, focusing on reproduction.
Adult Size of Angoumois grain moth
1.3 - 2 cm

How Can You Attract Angoumois grain moth
The use of pheromone traps or grain bait can be effective in attracting angoumois grain moth, considering their feeding preferences at various stages.
What is the Best Weather to Observe Angoumois grain moth
Adult angoumois grain moth prefer warm and dry conditions for flying and mating. Larval stages are less dependant on external weather conditions as they are often found indoors.
How and Where Can You Find Angoumois grain moth at Different Life Stages
Egg Eggs of angoumois grain moth are typically laid on grains. Inspect grains closely for small, whitish eggs that are often deposited in cracks or crevices.
Larva Larvae of angoumois grain moth bore into grains and feed from within. Look for larvae by examining stored grains for signs of damage, such as holes or frass (larval excrement).
Pupal Pupae of angoumois grain moth can be found within grains or in the debris at the bottom of the grain store. Sift through grain or debris to locate pupae, which are often in a cocoon-like structure.
Adult Adult angoumois grain moth can be attracted using light traps at night or by setting up pheromone traps in areas where they are suspected to be active.

Angoumois grain moth can bore into foods and damage them, especially various grains.
Are Angoumois grain moth harmful to humans?
No harm to health. Angoumois grain moths doesn't bite or transmit disease.
Grain-boring. The larvae can bore through grains, including wheat, barley, corn, rice, millet, and sorghum.
Contaminating food. Angoumois grain moth-contaminated corn emits a bad smell that hurts sales.
Where do Angoumois grain moth come from?
Usually, angoumois grain moths don't fly into indoor spaces, but they can be taken into human homes inadvertently in grains.
What is the most effective prevention against Angoumois grain moth?
Check for traces of angoumois grain moth activity. Examine grain packages for tiny holes. These traces indicate the possible presence of angoumois grain moths or other pests in the pantry.
Avoid buying products in comprised packaging, or anything with silk, web, or cocoons on the packaging.
Seal all solid foods. Keep all dried food in sealed containers to prevent pests from entering and infesting the food. Sealed containers also prevent those pests already in the food from spreading further.
Keep the food and the pantry dry. Storage pests breed much more under humid conditions. Moist food also emits a smell that attracts pests.

Stored Produce Pest
Angoumois grain moth poses a severe threat to dry storage, particularly to grains including wheat, maize, barley, rice, and sorghum. Both adults and larvae infest stored produce, with larvae causing the most damage by burrowing into grains, reducing their germination ability and nutritional value. Infestations often lead to significant economic losses and create a need for rigorous pest management in storage facilities.
Agricultural Pests
Larvae of angoumois grain moth are notorious for boring into the seeds of wheat, corn, and rice, causing mild to severe yield losses. Infestation signs include hollowed grains and visible frass. Severe infestations can lead to significant crop destruction, with direct financial impacts on the farming community and potential food supply disruptions.
