Which method is commonly used to control parasites in animals?

  1. Antibiotics

  2. Insecticides

  3. Vaccines

  4. Minerals

The correct answer is: Insecticides

Insecticides are specifically designed to target and control insect parasites that affect animals. These chemicals work by disrupting the lifecycle of the parasites, killing them or preventing their development. This makes them effective for managing infestations of external parasites such as fleas, ticks, and lice, which can cause health issues in animals if not controlled. Antibiotics are used to treat bacterial infections rather than parasites. Vaccines are preventive measures aimed at infectious diseases, not directly at parasites. Minerals, while important for overall animal health, do not have a role in parasite control. Therefore, insecticides stand out as the appropriate choice for managing parasitic problems in animals.
