Is there a problem with the small beetle in the bird's droppings?
Where did the little beetle come from?
In fact, small beetles are one of the food of swiftlet. After being eaten by the swiftlet, part of the eggs are not destroyed, so they are excreted to form a large number of small beetles in the swiftlet's droppings.
After these small beetles come out, they will continue to swallow and decompose the feces that can be eaten.
At the same time, some will fly to the bird's nest, causing the bird's nest to be more or less dirty. After being decomposed, bird's dropping will lose its original smell and become less attractive to swiftlet. Therefore, everyone is encouraged to clean the bird manure regularly and do a good job of pest control.
