Breeding in stagnant water, mosquitoes transmit diseases like malaria, dengue fever, Zika virus, and West Nile virus, making them significant vectors for human illnesses.


Bedbugs, often associated with unsanitary conditions, feed on blood and can cause itching and allergic reactions, posing health risks when infesting beds and furniture


Flies are attracted to decaying organic matter and feces, serving as vectors for diseases such as diarrhea and cholera by transferring pathogens from contaminated sources to food, water, and surfaces


Cockroaches, commonly found in dirty and damp places, carry pathogens on their bodies and can contaminate food and surfaces, contributing to disease spread


Rats thrive in unsanitary environments and are notorious carriers of diseases and parasites like fleas and ticks, potentially spreading illnesses like leptospirosis and salmonellosis


Pigeons, particularly in urban environments, can carry diseases and parasites due to their proximity to human waste and polluted areas
