“It is completely explainable with aphid calamity. In Varna, I think there were so many aphids about 20 years ago, but it is not unusual. And because the biggest enemy and favorite prey for ladybugs are aphids, so their population has developed very quickly, “said Dr. Antoaneta Toncheva, head of the municipal enterprise” DDD “- Varna.
And in order to restore the biological balance, in this case no human intervention is needed.
“When they reduce the food or eat most of the aphids, they will scatter themselves because they will go looking for food elsewhere,” explained Dr. Toncheva.
According to experts, ladybugs are in no way dangerous to humans, and their large number can melt literally in a day.
