Learn about the common pests, like weevils, that can infest stored dals. Discover how they get there and the best ways to prevent them.
1 Answer
Stored dals develop small black bugs, typically bean weevils or similar pests, because their eggs are often present in the dal from the field and hatch under favorable storage conditions. These bugs then feed on the dal, causing damage and multiplying.
Detailed Explanation:
The primary reason dals develop small black bugs during storage is due to the presence of insect eggs or larvae already within the dal grains when they are harvested and processed. These eggs are often laid by pests like bean weevils (also known as pulse beetles) in the field or during initial storage at the farm or processing facility. These eggs are very small and difficult to detect with the naked eye.Once the dal is stored in your pantry, the eggs hatch under favorable conditions such as warmth and humidity. The larvae then bore into the dal grains and feed on them, growing into adult beetles. These adult beetles then reproduce, laying more eggs and continuing the cycle. The small black bugs you see are typically the adult beetles or their larvae. The damage they cause not only reduces the nutritional value of the dal but also makes it unappetizing. The infestation can spread to other stored grains and pulses if not addressed promptly.
Pro Tip:
To prevent bug infestations in stored dals, consider freezing the dal for 3-4 days immediately after purchase. This will kill any existing eggs or larvae. After freezing, store the dal in airtight containers in a cool, dry place.
