Cockroaches are a common pest found in tropical climates such as Indonesia, and their preference for warm and humid environments makes them a frequent nuisance in urban areas. Mosquitoes, on the other hand, are known for carrying deadly diseases such as dengue fever, malaria, and Zika, which have contributed to a high number of fatalities in Indonesia. Flies, meanwhile, are carriers of disease due to their breeding grounds and feeding habits, which often involve animal waste and garbage. To manage these pests, methods such as fogging, fly glue application, and baiting gel can be used.
