    From Tropical Warehouse moth eggs to Tropical Warehouse moth adults

    The life cycle of the Tropical Warehouse Moth is a lengthy process, taking anywhere from 82 to 206 days at 21°C. A female moth lays approximately 260 eggs in her lifetime, often in groups and within various food products. This extended development period, from egg to imago, highlights the need for long-term monitoring and control strategies in affected environments.

    Infestation in commodities

    The Tropical Warehouse Moth primarily infests commodities like cocoa, grains, nuts, dried fruits, and flour. The larvae feed on these products, and mature larvae often leave the product to find a suitable place to pupate, such as cracks and crevices in storage areas. The damage caused by these moths is not limited to the consumption of food products but extends to contamination through feces, webs, dead moths, and fungi.

    Get rid of Tropical Warehouse moth

    Effective management of Tropical Warehouse Moth infestations involves both preventive and active control measures. Regular cleaning of vacant spaces and maintaining a low temperature in storage areas are key preventive strategies. Prioritizing the use of older stock first can also help mitigate infestation risks. When infestations occur, Controlled Atmosphere treatments are effective for infestations within products, while Heat Treatment is recommended for infestations in buildings.
