What are the disadvantage of millipede?

Millipedes can be a nuisance in gardens and homes, as they often invade spaces in search of moisture and decaying organic matter. While they are generally harmless, some species can secrete toxic chemicals as a defense mechanism, which can cause skin irritation in humans. Additionally, their feeding habits can lead to damage to plants and crops, particularly in large numbers. Overall, their presence can disrupt local ecosystems and lead to unwanted infestations.
